Tętniak aorty
Epidemiologia
Tętniak aorty, obejmujący głównie tętniaki aorty brzusznej (TAB) i piersiowej (TAP), stanowi istotne wyzwanie zdrowotne o globalnym zasięgu, z roczną śmiertelnością sięgającą 150 000-200 000 przypadków. Częstość występowania TAB w populacji 30-79 lat wynosi około 0,92% (95% CI: 0,65-1,30), z wyraźną przewagą u mężczyzn i osób rasy kaukaskiej. Najwyższa częstość występuje w regionie Zachodniego Pacyfiku (1,31%), a najniższa w Afryce (0,33%). Główne czynniki ryzyka to wiek >65 lat (ryzyko wzrasta o 6% na dekadę), płeć męska (4-5-krotnie wyższe ryzyko), palenie tytoniu (odpowiedzialne za 75% przypadków TAB), wywiad rodzinny, nadciśnienie tętnicze oraz choroby sercowo-naczyniowe. Badania przesiewowe, szczególnie u mężczyzn w wieku 65-75 lat z historią palenia, wykazały istotne zmniejszenie śmiertelności, co potwierdzają rekomendacje USPSTF oraz programy takie jak brytyjski NHS, oferujące USG jako metodę pierwszego wyboru do monitorowania tętniaków o średnicy ≥3 cm z różnymi interwałami kontroli zależnymi od wielkości tętniaka.

Epidemiologia tętniaka aorty
Tętniak aorty stanowi poważny problem zdrowotny o znaczących konsekwencjach epidemiologicznych na całym świecie. Choroba ta charakteryzuje się miejscowym poszerzeniem aorty, które może prowadzić do zagrażającej życiu rupture, związanej z wysoką śmiertelnością. Według globalnych szacunków, tętniaki aorty prowadzą do około 150 000-200 000 zgonów rocznie na całym świecie.12 W samych tylko Stanach Zjednoczonych co roku diagnozuje się około 200 000 nowych przypadków tętniaka aorty brzusznej (TAB).3
Rozpowszechnienie tętniaka aorty brzusznej
Globalna częstość występowania tętniaka aorty brzusznej wśród osób w wieku 30-79 lat wynosi około 0,92% (95% CI: 0,65-1,30), co przekłada się na łączną liczbę 35,12 miliona przypadków TAB na świecie w 2019 roku.45 Badania przesiewowe wskazują, że częstość występowania TAB wynosi od 3 do 8% w populacji objętej badaniami, dotycząc głównie mężczyzn. Należy jednak zauważyć, że większość tętniaków wykrytych podczas badań przesiewowych jest małych rozmiarów; tętniaki o średnicy ≥5,5 cm stwierdza się jedynie u 0,4-0,6% osób poddanych badaniom.6
Występowanie TAB różni się znacząco między regionami świata. Region Zachodniego Pacyfiku charakteryzuje się najwyższą częstością występowania TAB, wynoszącą 1,31% (95% CI: 0,94-1,85), podczas gdy region afrykański ma najniższą częstość – 0,33% (95% CI: 0,23-0,48).78 W Stanach Zjednoczonych częstość występowania TAB szacuje się na 2-4% populacji dorosłych, co stanowi około 1,1 miliona osób w wieku 50-84 lat.910
Rozpowszechnienie tętniaka aorty piersiowej
Tętniaki aorty piersiowej (TAP) występują rzadziej niż tętniaki aorty brzusznej. Częstość występowania TAP szacuje się na około 5,3-6 przypadków na 100 000 osobolat, a chorobowość na poziomie 0,16%.1112 Tętniaki aorty piersiowej zazwyczaj diagnozowane są po 60-65 roku życia. Mężczyźni są dotknięci TAP 2-4 razy częściej niż kobiety, jednak u kobiet obserwuje się gorsze wyniki leczenia.1314
Czynniki ryzyka i trendy demograficzne
Główne czynniki ryzyka rozwoju tętniaka aorty obejmują:151617
- Wiek powyżej 65 lat (ryzyko wzrasta o 6% na każdą dekadę życia)18
- Płeć męska (występowanie 4-5 razy częstsze niż u kobiet)
- Palenie tytoniu (odpowiada za około 75% wszystkich przypadków TAB)
- Wywiad rodzinny (ryzyko podwaja się u osób mających krewnych pierwszego stopnia z TAB)
- Nadciśnienie tętnicze
- Choroby sercowo-naczyniowe
- Obniżony poziom cholesterolu HDL
Znaczące różnice demograficzne obejmują:1920
- Wyższą częstość występowania TAB u osób rasy kaukaskiej (3,5 razy częściej niż u Afroamerykanów)
- Znacznie wyższą częstość u palaczy w porównaniu z niepalącymi (8:1)
- Stosunek mężczyzn do kobiet wynoszący około 3,7:1 w skali globalnej
Trendy epidemiologiczne
W ostatnich dziesięcioleciach zaobserwowano interesujące trendy w epidemiologii tętniaka aorty:2122
- Spadek częstości występowania TAB w krajach takich jak Wielka Brytania, Nowa Zelandia, Szwecja i Dania
- Zmniejszenie częstości występowania z 5,0% w 1991 roku do 1,3% w 2015 roku w badaniach przesiewowych
- Spadek częstości przypisywany zmniejszeniu rozpowszechnienia palenia tytoniu
- Jednak obserwuje się możliwy wzrost zachorowalności i śmiertelności z powodu TAB w regionach Ameryki Łacińskiej, Azji i Pacyfiku oraz Afryki23
Nadzór i obserwacja tętniaka aorty
Systematyczny nadzór nad tętniakiem aorty jest kluczowym elementem opieki nad pacjentami z tym schorzeniem, umożliwiającym wczesne wykrycie powiększenia tętniaka i podjęcie odpowiednich działań terapeutycznych, zanim dojdzie do potencjalnie śmiertelnego pęknięcia.2425
Programy przesiewowe
Badania przesiewowe w kierunku tętniaka aorty brzusznej wykazały istotne korzyści pod względem zmniejszenia śmiertelności związanej z TAB.2627 Znaczące zalecenia dotyczące badań przesiewowych obejmują:
- Amerykańska Grupa Zadaniowa ds. Usług Profilaktycznych (USPSTF) zaleca jednorazowe badanie przesiewowe w kierunku TAB za pomocą USG u mężczyzn w wieku 65-75 lat, którzy kiedykolwiek palili tytoń2829
- Selektywne oferowanie badań przesiewowych mężczyznom w wieku 65-75 lat, którzy nigdy nie palili30
- Niewystarczające dowody dotyczące korzyści z badań przesiewowych u kobiet w wieku 65-75 lat, które kiedykolwiek paliły lub mają wywiad rodzinny w kierunku TAB31
- Zalecenie przeciwko rutynowym badaniom przesiewowym u kobiet, które nigdy nie paliły i nie mają wywiadu rodzinnego w kierunku TAB32
W Wielkiej Brytanii funkcjonuje Narodowy Program Badań Przesiewowych w kierunku TAB, który oferuje badanie USG wszystkim mężczyznom w roku, w którym kończą 65 lat. Wskaźnik uczestnictwa w tym programie wynosi około 80%, co jest wyższym wynikiem niż w większości programów badań przesiewowych dla dorosłych.33 Programy te przyczyniły się do stałego spadku liczby zgonów u mężczyzn z powodu pękniętego TAB w ciągu ostatniej dekady.34
Protokoły nadzoru
Nadzór nad tętniakiem aorty opiera się głównie na okresowej ocenie średnicy aorty, która jest najsilniejszym predyktorem ryzyka pęknięcia.3536 Zalecane interwały nadzoru różnią się w zależności od wielkości tętniaka:
| Średnica tętniaka aorty brzusznej | Zalecany odstęp między badaniami kontrolnymi |
|---|---|
| 3,0-3,9 cm | Co 2-3 lata |
| 4,0-4,9 cm | Co 12 miesięcy |
| 5,0-5,4 cm | Co 6 miesięcy |
Powyższe zalecenia są zgodne z wytycznymi Towarzystwa Chirurgii Naczyniowej oraz programem badań przesiewowych NHS.373839 Dla tętniaka aorty piersiowej zaleca się wyjściowe badanie po miesiącu od rozpoznania, a następnie coroczne kontrole, jeśli pomiary są stabilne.40
Specjalistyczny nadzór jest szczególnie zalecany dla pacjentów:4142
- Z rodzinnym wywiadem tętniaka aorty piersiowej
- Z chorobami tkanki łącznej (np. zespół Marfana, zespół Loeysa-Dietza)
- Po zabiegach naprawczych tętniaka (szczególnie po wewnątrznaczyniowej naprawie tętniaka – EVAR)
Metody obrazowania w nadzorze
W nadzorze nad tętniakiem aorty wykorzystuje się różne metody obrazowania:4344
- Ultrasonografia (USG) – metoda pierwszego wyboru do badań przesiewowych i nadzoru TAB ze względu na:
- Brak promieniowania jonizującego
- Niski koszt
- Wysoką czułość (94-100%) i swoistość (98-100%)45
- Łatwą dostępność
- Tomografia komputerowa (CT/CTA) – szczególnie przydatna do:
- Potwierdzenia diagnozy
- Oceny całej aorty
- Planowania leczenia
- Nadzoru po EVAR
- Rezonans magnetyczny (MRI/MRA) – alternatywa dla CT, zwłaszcza u pacjentów:
- Uczulonych na środki kontrastowe
- Z niewydolnością nerek
- Wymagających częstych kontroli obrazowych
Nowe podejścia w nadzorze obejmują analizę objętościową tętniaka, która może być bardziej czuła niż pomiary średnicy, szczególnie po zabiegach EVAR.4647 Badania sugerują, że zmiany objętości mogą wcześniej sygnalizować niepowodzenie leczenia, umożliwiając wcześniejszą interwencję.
Innowacje w nadzorze nad tętniakiem aorty
Ostatnie lata przyniosły znaczące innowacje w nadzorze nad tętniakiem aorty, które mogą poprawić wykrywanie, monitorowanie i zarządzanie tą chorobą.48
Sztuczna inteligencja i systemy nadzoru
Sztuczna inteligencja (AI) jest coraz częściej wykorzystywana do usprawnienia nadzoru nad tętniakiem aorty:4950
- UC Davis Health we współpracy z firmą Illuminate opracowali scentralizowany program nadzoru nad TAB wykorzystujący AI
- Program identyfikuje pacjentów z grupy ryzyka, którzy nie pojawili się na wizytach kontrolnych z powodu pandemii lub innych czynników
- W pierwszych ośmiu miesiącach program zidentyfikował ponad 11 600 pacjentów z TAB, którzy mogli skorzystać z monitorowania
- Spośród 10 600 przeanalizowanych pacjentów, 950 osób, które przerwały leczenie, zostało objętych aktywnym nadzorem
- Program doprowadził do 151 badań diagnostycznych i 13 ratujących życie zabiegów chirurgicznych
Zaawansowane techniki pomiarowe
Tradycyjny nadzór nad tętniakiem aorty opiera się głównie na pomiarach maksymalnej średnicy tętniaka, jednak pojawiają się nowe, obiecujące metody:5152
- Analiza objętościowa tętniaka – może dostarczyć dodatkowych informacji o ryzyku pęknięcia i dynamice wzrostu tętniaka:
- Modelowanie materiałowe i obliczeniowa dynamika płynów – te zaawansowane techniki mogą przewidywać:55
- Jak tętniaki będą się rozwijać
- Potencjalną lokalizację i czas pęknięcia
- Naprężenia ściany tętniaka
Programy obserwacji po leczeniu
Nadzór jest równie istotny po leczeniu tętniaka aorty, szczególnie po zabiegach wewnątrznaczyniowych (EVAR):5657
- Pacjenci po EVAR powinni być włączeni do programu obserwacji obrazowej ze względu na ryzyko:
- Przecieków wewnętrznych (endoleaks)
- Migracji stentu
- Powiększania się worka tętniaka
- Europejskie Towarzystwo Chirurgii Naczyniowej (ESVS) sugeruje, że pacjenci z niskim ryzykiem niepowodzenia EVAR, na podstawie pierwszego pooperacyjnego badania CTA, mogą być rozważani do rzadszych badań kontrolnych58
- Zintegrowane programy obserwacji tętniaka aorty oferują kompleksową opiekę, w tym:5960
- Regularne wizyty kontrolne
- Spersonalizowaną edukację na temat bezpiecznych aktywności
- Wsparcie dla pacjentów i rodzin
- Monitoring rodzinnych skupisk tętniaków aorty
Znaczenie epidemiologiczne i wyzwania w nadzorze
Wpływ na zdrowie publiczne
Tętniak aorty stanowi istotne wyzwanie dla zdrowia publicznego ze względu na:6162
- Wysoką śmiertelność związaną z pęknięciem (55-95%)
- Tętniak aorty brzusznej jest 15. wiodącą przyczyną zgonów w USA i 10. wiodącą przyczyną zgonów u mężczyzn powyżej 55. roku życia
- Pęknięty TAB wiąże się z 70-95% śmiertelnością63
- Globalne obciążenie chorobą wynosi około 170 000 zgonów i 3 miliony lat życia skorygowanych niepełnosprawnością (DALY) rocznie64
- Rosnącą częstość występowania tętniaka aorty o wczesnym początku (wiek 15-39 lat) w ostatnich trzech dekadach, szczególnie w krajach o niższym wskaźniku rozwoju społeczno-demograficznego6566
Wczesne wykrywanie i koszty
Wczesne wykrywanie i odpowiedni nadzór nad tętniakiem aorty mają znaczący wpływ na wyniki leczenia i koszty:6768
- Śmiertelność związana z planową naprawą tętniaka jest znacznie niższa niż w przypadku naprawy pękniętego TAB
- Zgony z powodu TAB można zapobiec poprzez wczesne wykrycie i odpowiednie, terminowe leczenie
- Programy badań przesiewowych pozostają efektywne kosztowo mimo spadającej częstości występowania TAB u 65-letnich mężczyzn69
- Większość TAB wykrytych w badaniach przesiewowych (90%) ma średnicę między 3,0 a 5,5 cm, poniżej progu kwalifikującego do zabiegu chirurgicznego70
Wyzwania w nadzorze
Pomimo postępów w nadzorze nad tętniakiem aorty, nadal istnieją znaczące wyzwania:7172
- Brak opartych na dowodach wytycznych dotyczących nadzoru nad tętniakami aorty piersiowej o średniej wielkości (≤5 cm)
- Potencjalne nadmierne obrazowanie u pacjentów z grupy niższego ryzyka, co wiąże się z niepotrzebnym narażeniem na promieniowanie
- Ograniczone dane epidemiologiczne dotyczące tętniaka aorty o wczesnym początku73
- Brak standardowego systemu nadzoru do oceny długoterminowych wyników stentgraftów aortalnych w praktyce klinicznej74
- Ograniczone dane dotyczące skuteczności nadzoru w różnych populacjach (np. u osób starszych, kobiet i różnych grup etnicznych)75
Przyszłość nadzoru nad tętniakiem aorty
Przyszłe kierunki w nadzorze nad tętniakiem aorty obejmują:7677
- Rozwój algorytmów predykcyjnych do identyfikacji pacjentów wymagających częstszego nadzoru
- Zastosowanie spersonalizowanych protokołów nadzoru w oparciu o indywidualne czynniki ryzyka
- Integrację danych z rejestrów i roszczeń ubezpieczeniowych w celu systematycznego nadzoru nad długoterminowymi wynikami78
- Badania identyfikujące małe tętniaki o dużej objętości z wysokim ryzykiem pęknięcia79
- Badania oceniające skuteczność nadzoru i leczenia w różnorodnych populacjach80
- Większy nacisk na nadzór nad tętniakiem aorty o wczesnym początku, szczególnie w regionach Azji i Afryki81
Warto zwrócić uwagę na toczące się badania kliniczne, takie jak TITAN SvS, które porównuje śmiertelność z wszystkich przyczyn i częstość występowania ostrych zdarzeń aortalnych między nadzorem a wczesną elektywną operacją aorty wstępującej u pacjentów z tętniakiem aorty wstępującej o średnicy 5,0-5,5 cm.8283 Wyniki tego badania mogą dostarczyć opartych na dowodach wytycznych dotyczących odpowiedniego postępowania z tętniakiem aorty wstępującej w oparciu o kryteria wielkości.
Podsumowanie epidemiologii i nadzoru tętniaka aorty
Tętniak aorty stanowi istotny problem zdrowia publicznego o globalnym znaczeniu, charakteryzujący się znacznymi różnicami regionalnymi i demograficznymi w częstości występowania. Skuteczny nadzór nad tętniakiem aorty jest kluczowy dla zmniejszenia śmiertelności i zapewnienia optymalnej opieki. Obejmuje on regularne monitorowanie za pomocą odpowiednich badań obrazowych, z częstotliwością dostosowaną do wielkości tętniaka i indywidualnych czynników ryzyka pacjenta.8485
Badania przesiewowe w kierunku TAB u osób z grupy wysokiego ryzyka, szczególnie u mężczyzn w wieku 65-75 lat z historią palenia tytoniu, wykazały znaczną redukcję śmiertelności związanej z tętniakiem. Innowacyjne podejścia, takie jak analiza objętościowa, modelowanie komputerowe i wykorzystanie sztucznej inteligencji, obiecują poprawę skuteczności nadzoru i personalizację opieki.8687
Przyszłe badania powinny skupić się na optymalizacji protokołów nadzoru, identyfikacji nowych biomarkerów prognostycznych i ocenie efektywności kosztowej różnych strategii nadzoru. Potrzebne są także badania epidemiologiczne w regionach o ograniczonych danych, aby lepiej zrozumieć globalne obciążenie chorobą i opracować ukierunkowane strategie zapobiegania i kontroli.8889

Aortic aneurysm is a chronic disease characterized by localized expansion of the aorta, including the ascending aorta, arch, descending aorta, and abdominal aorta. […] Aortic aneurysms are estimated to lead to 150,000~200,000 deaths per year worldwide. […] Aortic aneurysm is a chronic aortic disease characterized by permanent localized dilatation of the aorta through adverse remodeling of the aortic wall, and it can subsequently progress to life-threatening consequences through aortic rupture, which has a mortality of over 80% and causes 150,000-200,000 deaths each year worldwide. […] Aortic aneurysms are generally classified as thoracic aortic aneurysms (TAAs), which form in the ascending aorta, the arch, or the aorta above the diaphragm, or abdominal aortic aneurysms (AAAs), which are localized in the aorta below the diaphragm in the supra- or infrarenal regions.
- #2 Aortic aneurysm – Wikipediahttps://en.wikipedia.org/wiki/Aortic_aneurysm
According to a review of global data through 2019, the prevalence of abdominal aortic aneurysm worldwide was about 0.9% in people under age 79 years, and is about four times higher in men than in women at any age. Death occurs in about 55-64% of people having rupture of the AAA. […] Screening with ultrasound is indicated in those at high risk. Prevention is by decreasing risk factors, such as smoking, and treatment is either by open or endovascular surgery. Aortic aneurysms resulted in about 152,000 deaths worldwide in 2013, up from 100,000 in 1990. […] Globally, aortic aneurysms resulted in about ~170,000 deaths in 2017. This figure represents an increase from approximately ~100,000 in 1990.
- #3 Patients with Abdominal Aortic Aneurysm (AAA) | Society for Vascular Surgeryhttps://vascular.org/node/87
Every year, 200,000 people in the U.S. are diagnosed with an abdominal aortic aneurysm (AAA), a dilation of the main artery within the abdomen. […] A ruptured AAA is the 15th leading cause of death in the country (~4,500 cases/yr) and the 10th leading cause of death in men older than 55. AAAs occur in up to 13 percent of men and 6 percent of women over the age of 65. […] Because the mortality associated with elective aneurysm repair is drastically lower than following repair of a ruptured AAA, the emphasis must be on early detection and repair prior to the occurrence of rupture. […] Death from AAA is preventable with early detection and appropriate, timely treatment. […] Screening for AAA in specific patient populations has been shown to improve disease mortality and can be done without any patient risk using duplex ultrasound.

Objective: To estimate the global and regional prevalence and cases of abdominal aortic aneurysms (AAAs) in 2019 and to evaluate major associated factors. […] Understanding the global prevalence of AAA is essential for optimizing health services and reducing mortality from reputed AAA. […] We retained 54 articles across 19 countries. The global prevalence of AAA among persons aged 30 to 79 years was 0.92% (95% CI, 0.65-1.30), translating to a total of 35.12 million (95% CI, 24.94-49.80) AAA cases in 2019. […] In 2019, the Western Pacific region had the highest AAA prevalence at 1.31% (95% CI, 0.94-1.85), whereas the African region had the lowest prevalence at 0.33% (95% CI, 0.23-0.48). […] A substantial proportion of people are affected by AAA. There is a need to optimize epidemiological studies to promptly respond to at-risk and identified cases to improve outcomes.

- #6 Epidemiology, risk factors, pathogenesis, and natural history of abdominal aortic aneurysm – UpToDatehttps://www.uptodate.com/contents/epidemiology-risk-factors-pathogenesis-and-natural-history-of-abdominal-aortic-aneurysm
Epidemiology, risk factors, pathogenesis, and natural history of abdominal aortic aneurysm […] The epidemiology, risk factors, pathogenesis, and natural history of AAA are reviewed here. The prevalence of abdominal aortic aneurysm (AAA) is 3 to 8 percent in screening studies, affecting predominantly males. However, AAAs found on screening are generally small; those measuring â¥5.5 cm or greater are found in only 0.4 to 0.6 percent of those screened. Because the incidence of AAA rises sharply in individuals over 60 years of age, the future prevalence of AAA could increase substantially in association with the aging population. On the other hand, some suggest that a reduction in the prevalence of smoking could have the opposite effect, with several studies citing a lower prevalence of AAA in 65- to 80-year-old White adults.

- #9 Abdominal Aortic Aneurysm: Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/7153-abdominal-aortic-aneurysm
Abdominal aortic aneurysms are a common condition. […] They occur in about 1.4% of adults between the ages of 50 and 84 in the U.S. This is around 1.1 million people. […] They occur in between 1% and 2% of males over age 65. With each additional decade of life the risk of developing an AAA doubles. […] Theyre four times more common in males. […] They occur in about 1% of females over 70 with a history of smoking. […] Aneurysms can form anywhere along your aorta, but they usually form in your belly. Abdominal aortic aneurysms represent about 75% of all aortic aneurysms. […] AAAs are more common among white people compared to Black people and Asian people. […] AAAs most often affect people males. But when they form in females, they have a higher risk of rupturing at smaller sizes as well as occurring in family members.
- #10 Abdominal aortic aneurysm epidemiology and demographics – wikidochttps://www.wikidoc.org/index.php/Abdominal_aortic_aneurysm_epidemiology_and_demographics
Abdominal aortic aneurysm is the 13th leading cause of death in the US. Abdominal aortic aneurysms are more common in developed countries. Elderly, caucasian males who are smokers are at a higher risk for developing an abdominal aortic aneurysm. […] The incidence of abdominal aortic aneurysms increases after age 60 and peaks in the seventh and eighth decades of life. […] The prevalence among males over 60 years is 2000-6000/100,000. […] Abdominal aortic aneurysms (AAA) is a disease of the elderly, and is the 10th leading cause of death in older men in the United States. […] An individual’s risk of AAA increases by 6% per decade of life. […] Rupture of the AAA occurs in 1-3% of men aged 65 or more with an associated mortality rate of 70-95%. […] AAA tends to cluster in families, therefore affecting younger members of families in the absence of traditional acquired risk factors.
- #11 Incidence and Prevalence of Thoracic Aortic Aneurysms: A Systematic Review and Meta-analysis of Population-Based Studies – PubMedhttps://pubmed.ncbi.nlm.nih.gov/33705940/
Thoracic aortic aneurysms (TAA) may grow asymptomatically until they rupture, with a mortality over 90%. The true incidence and prevalence of this condition is uncertain and epidemiologic data is scarce, understudied and dispersed. Therefore, we aimed to conduct a systematic review and meta-analysis of the incidence and prevalence of TAAs in population-based studies. […] The pooled incidence and prevalence of TAAs was 5.3 per 100,000 individuals/year (95% confidence interval [CI]: 3.0; 8.3) and 0.16% (95% CI: 0.12; 0.20), respectively. The pooled incidence of ruptured aneurysms was 1.6 per 100,000 individuals/year (95% CI: 1.3; 2.1). […] The current epidemiologic information provided serve as a base for future public-health decisions. The lack of well-design population-base studies and the limitations encountered serve as calling for future research in this field.
- #12 Thoracic Aortic Aneurysm: Practice Essentials, Anatomy, Pathophysiologyhttps://emedicine.medscape.com/article/424904-overview
Although findings from autopsy series have varied widely, the prevalence of aortic aneurysms probably exceeds 3-4% in individuals older than 65 years. Aortic aneurysms are more common in men than in women and are more common in persons with COPD than in those without lung disease. […] The incidence of TAAs has been estimated to be about 6 cases per 100,000 person-years. In a systematic review and meta-analysis of the incidence and prevalence of TAAs in 22 population-based studies, Melo et al found a pooled incidence of 5.3 per 100,000 individuals per year and a prevalence of 0.16%. […] Death from aneurysmal rupture has been one of the 15 leading causes of death in most series. In addition, the overall prevalence of aortic aneurysms has increased significantly in the past 30 years. This is partly due to an increase in diagnosis based on the widespread use of imaging techniques. However, the prevalence of fatal and nonfatal rupture has also increased, suggesting a true increase in prevalence.

Thoracic aortic aneurysms are relatively uncommon (6 to 10 new ones per 100,000 person years) and are less prevalent than abdominal aortic aneurysm. Thoracic aortic aneurysms are generally diagnosed after the sixth and seventh decades of life. Although men are affected 2 to 4 times as often as women, women are at higher risk of rupture by a factor 6.8. […] TAAs are relatively uncommon with an estimated incidence between 6 and 10 new aneurysms per 100,000 person-years. According to a study by Beckerstaff et al., the incidence of thoracic aortic aneurysms was reported to be 5.3 per 100,000 per year. Another study done by Clouse et al. showed the incidence to be 10.4 per 100,000 per year. […] However, the incidence and prevalence of TAD has been increasing in the past years. The annual number of surgeries performed on the aorta have increased, along with improved post-surgical and long term survival. […] TAAs are usually diagnosed after the sixth and seventh decade of life. […] Males are affected approximately two to four times more often than females. […] Thoracic aortic aneurysm is more common in caucasians.
- #15 Abdominal Aortic Aneurysm | AAFPhttps://www.aafp.org/pubs/afp/issues/2015/0415/p538.html
Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. The natural history of AAA shows that as aneurysms increase in size, they expand at a greater rate and the risk of rupture increases. Therefore, in persons found to have aneurysms on initial screening, regular surveillance is needed every six months to three years, depending on aneurysm size. Current guidelines do not advocate rescreening persons with an aortic diameter smaller than 3.0 cm.
- #16 Recommendation: Abdominal Aortic Aneurysm: Screening | United States Preventive Services Taskforcehttps://www.uspreventiveservicestaskforce.org/uspstf/recommendation/abdominal-aortic-aneurysm-screening
Important risk factors for AAA include older age, male sex, smoking, and having a first-degree relative with an AAA. […] Epidemiologic literature commonly defines an ever smoker as someone who has smoked 100 or more cigarettes. […] Indirect evidence shows that smoking is the strongest predictor of AAA prevalence, growth, and rupture rates. […] Family history of AAA in a first-degree relative doubles the risk of developing AAA. […] The primary method of screening for AAA is conventional abdominal duplex ultrasonography. […] Evidence is adequate to support 1-time screening for men who have ever smoked. […] The majority of screen-detected AAAs (90%) are between 3.0 and 5.5 cm in diameter and thus below the usual threshold for surgery. […] The current standard of care for patients with stable smaller aneurysms is to maintain ultrasound surveillance at regular intervals because the risk of rupture is small.

Abdominal aortic aneurysms (AAAs) are found in up to 8% of men aged 65 years, yet usually remain asymptomatic until they rupture. […] Rupture of an AAA and its associated catastrophic physiological insult carries overall mortality in excess of 80%, and 2% of all deaths are AAA-related. […] Risk factors for AAAs include increasing age, male sex, smoking, and low HDL-cholesterol levels. […] Screening programs target men aged 65 years, as this group is at highest risk of developing an abdominal aortic aneurysm. […] Endovascular repair has substantially reduced perioperative morbidity and mortality of abdominal aortic aneurysms. […] Centralization of vascular surgical services has led to improved outcomes among patients with an abdominal aortic aneurysm.

Abdominal aortic aneurysm is the 13th leading cause of death in the US. Abdominal aortic aneurysms are more common in developed countries. Elderly, caucasian males who are smokers are at a higher risk for developing an abdominal aortic aneurysm. […] The incidence of abdominal aortic aneurysms increases after age 60 and peaks in the seventh and eighth decades of life. […] The prevalence among males over 60 years is 2000-6000/100,000. […] Abdominal aortic aneurysms (AAA) is a disease of the elderly, and is the 10th leading cause of death in older men in the United States. […] An individual’s risk of AAA increases by 6% per decade of life. […] Rupture of the AAA occurs in 1-3% of men aged 65 or more with an associated mortality rate of 70-95%. […] AAA tends to cluster in families, therefore affecting younger members of families in the absence of traditional acquired risk factors.

In 2019, the prevalence of AAA in people aged 30 to 79 years globally was 0.92% (95% CI, 0.651.30). […] It was 3.7-times greater in males than in females. […] After applying the demographic profile in 2019, these translated to a total of 35.12 million (95% CI, 24.9449.80) people aged 30 to 79 years that were living with AAA in 2019. […] Among the affected cases, around 79% were males. […] The age-specific and sex-specific prevalence rates of AAA at the global level are listed in Table 1. […] Advanced age, male sex, hypertension, hypercholesterolemia, obesity, smoking (ever, former or current), family history of AAA, CVD, cerebrovascular disease, claudication, peripheral artery disease, pulmonary disease, and renal disease were all revealed to be significantly associated with a higher odds of AAA.

The annual incidence of new AAA diagnoses is approximately 0.4 to 0.67 percent in Western populations. This equates to 2.5 to 6.5 aneurysms per 1000 person-years. Age significantly impacts the incidence. As an example, in one study, among males aged 65 to 74 years, the incidence was 55 per 100,000 person-years, increasing to 112 per 100,000 person-years for males aged 75 to 85 years, and further increasing to 298 per 100,000 person-years for those older than 85. […] The incidence of AAA discovery may be decreasing, however. In a screening study that included 81,150 men, the overall prevalence of screen-detected AAA (diameter >3.0 cm) was 3.4 percent, decreasing from 5.0 percent in 1991 to 1.3 percent in 2015. AAA expansion rates were unchanged. Among males who initially had a subaneurysmal aorta (2.6 to 2.9 cm), 57.6 percent were estimated to develop an AAA of â¥3.0 cm within 5 years of the initial scan, and 28.0 percent to develop a large AAA (>5.5 cm) within 15 years.

The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for AAA with ultrasonography in women aged 65 to 75 years who have ever smoked or have a family history of AAA. […] An AAA is typically defined as aortic enlargement with a diameter of 3.0 cm or larger. […] The prevalence of AAA has declined over the past 2 decades among screened men 65 years or older in various countries such as the United Kingdom, New Zealand, Sweden, and Denmark. […] Population-based studies in men older than 60 years have found an AAA prevalence ranging from 1.2% to 3.3%. […] The reduction in prevalence is attributed to the decrease in smoking prevalence over time. […] The current prevalence of AAA in the United States is unclear because of the low uptake of screening.

A substantial proportion of people are affected by AAA. There is a need to optimize epidemiological studies to promptly respond to at-risk and identified cases to improve outcomes. […] Epidemiological reports on AAA vary across age, sex, and locations worldwide. […] Most studies have identified advanced age, male sex, ever smoking, high blood pressure, and family history of AAA as the most important risk factors driving the burden of AAA. […] In 2017, the Global Burden of Disease (GBD) collaborators reported that AAA accounted for ~170,000 deaths and 3 million disability-adjusted life years worldwide. […] Despite these figures, the true global burden of AAA remains vague. […] Some authors noted that, despite a seemingly decreasing trend in AAA, prevalence and mortality in settings across Latin America, Asia Pacific, and Africa may be increasing.

Aneurysm of the thoracic aorta is less common than in the abdominal aorta, but it is clinically important because of the risk of rupture and death. […] Surveillance with various imaging tests is critical before and after intervention to guide treatment. […] Guidelines from several professional societies are available regarding surveillance and indications for intervention. […] Regular imaging surveillance is critical after diagnosis and after aneurysm interventions. […] There are no effective preventive strategies for TAA to date; thus, early detection, surveillance, and treatment are critical to improving outcomes. Guidelines are available.

On the basis of evidence showing substantial benefit, the US Preventive Services Task Force (USPSTF) recommends one-time ultrasonography screening for men aged 65-75 years who have ever smoked. […] The justification for screening programs has been further revisited by the publication of a 2017 meta-analysis of all reported trials, which concluded that screening reduces AAA-related deaths (odds ratio [OR] 0.66, 95% CI: 0.47, 0.93, P 0.02). […] While aortic aneurysm surveillance is generally recommended on the basis of maximal aortic diameter, it is recognised that this is merely a crude surrogate marker for rupture risk.

Every year, 200,000 people in the U.S. are diagnosed with an abdominal aortic aneurysm (AAA), a dilation of the main artery within the abdomen. […] A ruptured AAA is the 15th leading cause of death in the country (~4,500 cases/yr) and the 10th leading cause of death in men older than 55. AAAs occur in up to 13 percent of men and 6 percent of women over the age of 65. […] Because the mortality associated with elective aneurysm repair is drastically lower than following repair of a ruptured AAA, the emphasis must be on early detection and repair prior to the occurrence of rupture. […] Death from AAA is preventable with early detection and appropriate, timely treatment. […] Screening for AAA in specific patient populations has been shown to improve disease mortality and can be done without any patient risk using duplex ultrasound.

The main finding of this review is the steady decline in deaths in men from rAAA during the decade of study. […] The screening programme itself has been shown to be effective. Almost 3.5 million men have been invited for screening, with an uptake of around 80% – higher than almost all the adult national screening programmes. […] The question is, how much of the reduction in death from rAAA is due to screening and how much is due to changes in disease prevalence and other improvements in healthcare? […] The best evidence comes from the NVR, where the reduction in the number of rAAA was by approximately two thirds in the screened cohort and only a half in the non-screened cohort.

The aim of this report was to assess the effectiveness of population screening for AAA in men aged 65, by reviewing the AAA screening programmes across the UK between 2013 and 2023. […] The aim was to review the data collected by the 4 UK programmes in England, Scotland, Wales and Northern Ireland. Additionally, national statistics were obtained from the 4 nations on admissions to hospital for rAAA and deaths recorded with an underlying cause of rAAA. […] The AAA screening programmes in the UK aim to reduce AAA-related deaths in men by identifying aneurysms at a stage before rupture is likely to have occurred. Surveillance and treatment can then be offered at the appropriate stage to reduce the risk of AAA rupture, emergency hospital treatment, and death. […] It can be concluded that the AAA screening programmes in the UK are effective and contribute substantially to ongoing reductions in AAA-related mortality (deaths).

Abdominal aortic aneurysm is a pathologic condition with progressive abdominal aortic dilatation of 3.0 cm or more that predisposes the abdominal aorta to rupture. […] The risk factors for abdominal aortic aneurysm include hypertension, coronary artery disease, tobacco use, male sex, a family history of abdominal aortic aneurysm, age older than 65 years, and peripheral artery disease. […] Surveillance of abdominal aortic aneurysm depends on the size and growth rate of the aneurysm. […] Although definitive recommendations and evidence for AAA surveillance are lacking, the American College of Cardiology/American Heart Association and the Society for Vascular Surgery provide guidance based on the size of the aneurysm. […] The risk of growth increases with aneurysm size. […] Therefore, it is reasonable to repeat ultrasonography for aneurysms with a diameter of 3.0 cm to 3.9 cm every two to three years, and every six to 12 months for aneurysms 4.0 cm to 4.9 cm.

[…] The NHS offers an ultrasound scan to men during the screening year (1 April to 31 March) in which they turn 65. […] The purpose of the programme is to identify any swelling in the aorta at an early stage to reduce deaths from AAAs. […] Men are placed under surveillance if they are found to have a small or medium aneurysm, to see if the aneurysm increases in size. […] Surveillance requirements relate to the process of scanning men with aneurysms between 3cm to 5.4cm to check if their AAAs are getting bigger.

Experts at the Smidt Heart Institute’s new Aortic Surveillance Clinic will monitor patients with aortic aneurysms or enlarged aortas. The Smidt Heart Institute at Cedars-Sinai has opened an Aortic Surveillance Clinic for the evaluation and long-term monitoring of patients with enlarged aortas, or aortic aneurysms, for whom surgery may not be necessary. Through the Aortic Surveillance Clinic, we offer reassurance that they are being carefully and closely monitored and that proper therapy, including surgery, will be offered if needed. Aortic surgeons know that over time, they will accumulate hundreds of patients with aneurysms that they are following and not operating on. Careful monitoring of a significantly enlarged aorta, or aortic aneurysm, can help prevent the possibility of a life-threatening condition, such as aortic dissection. The Aortic Surveillance Clinic also provides expert care for patients with certain genetic syndromes, such as connective tissue disorders like Marfan syndrome and Loeys-Dietz syndrome, as well as other genetic disorders affecting the aorta and aortic valve. We are pleased to have the ability to focus on a subset of patients when they don’t need surgery and educate them on how to prevent acute aortic events, which can be fatal.

The estimated prevalence of AAA in women is reportedly less than that in men. […] Operative mortality associated with AAA is higher in women than in men. […] Evidence is insufficient to accurately characterize current practice patterns related to screening for AAA in women. […] This recommendation incorporates new evidence and replaces the 2014 USPSTF recommendation. […] The USPSTF examined evidence regarding the effectiveness of 1-time and repeated screening for AAA, the associated harms of screening, and the benefits and harms of available treatments for small AAAs (3.0-5.4 cm in diameter) identified through screening. […] Ultrasonography is the primary method used to screen for AAA in primary care because of its high sensitivity (94%-100%) and specificity (98%-100%). […] Each of the 4 older screening trials and a more recent population-based screening RCT showed an increase in elective operations in the intervention vs control group.

[…] A ruptured AAA is the 15th leading cause of death in the country (~4,500 cases/yr) and the 10th leading cause of death in men older than 55. AAAs occur in up to 13 percent of men and 6 percent of women over the age of 65. […] Because the mortality associated with elective aneurysm repair is drastically lower than following repair of a ruptured AAA, the emphasis must be on early detection and repair prior to the occurrence of rupture.

Aortic aneurysms are a common finding in elderly patients. Rupture of an aortic aneurysm is a catastrophic event associated with a very high mortality. […] Screening of men aged 65 years and over has been shown to reduce aneurysm related mortality, however, no formal screening guidelines exist in Australia. In addition to the risk of aneurysm expansion and rupture, patients are at increased risk of cardiovascular morbidity and mortality. Small aneurysms should be managed with surveillance and cardiovascular risk factor modification. Large aneurysms should be referred promptly to a vascular surgeon for assessment and repair.

The main finding of this review is the steady decline in deaths in men from rAAA during the decade of study. […] The screening programme itself has been shown to be effective. Almost 3.5 million men have been invited for screening, with an uptake of around 80% – higher than almost all the adult national screening programmes. […] The question is, how much of the reduction in death from rAAA is due to screening and how much is due to changes in disease prevalence and other improvements in healthcare? […] The best evidence comes from the NVR, where the reduction in the number of rAAA was by approximately two thirds in the screened cohort and only a half in the non-screened cohort.

Important risk factors for AAA include older age, male sex, smoking, and having a first-degree relative with an AAA. […] Epidemiologic literature commonly defines an ever smoker as someone who has smoked 100 or more cigarettes. […] Indirect evidence shows that smoking is the strongest predictor of AAA prevalence, growth, and rupture rates. […] Family history of AAA in a first-degree relative doubles the risk of developing AAA. […] The primary method of screening for AAA is conventional abdominal duplex ultrasonography. […] Evidence is adequate to support 1-time screening for men who have ever smoked. […] The majority of screen-detected AAAs (90%) are between 3.0 and 5.5 cm in diameter and thus below the usual threshold for surgery. […] The current standard of care for patients with stable smaller aneurysms is to maintain ultrasound surveillance at regular intervals because the risk of rupture is small.

[…] This is a prospective, multi-centre randomized control trial that compares the all-cause mortality, aneurysm-related aortic events, rate of stroke, and quality of life for those patients undergoing early elective ascending aortic surgery to those patients undergoing surveillance. […] The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. […] The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations.

The TITAN SvS trial compares the chance of dying or suffering tearing or rupture of the aorta between patients with an ascending aorta between 5.0 to 5.5 cm assigned to early surgery or surveillance. […] The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. […] The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations. […] Patients with ascending aortic aneurysm with a diameter of 4.5 cm – 4.9 cm will be observed with serial CT, and will be considered for enrollment into the trial once the aneurysm reaches 5.0 cm.

Aneurysm of the thoracic aorta is less common than in the abdominal aorta, but it is clinically important because of the risk of rupture and death. […] Surveillance with various imaging tests is critical before and after intervention to guide treatment. […] Guidelines from several professional societies are available regarding surveillance and indications for intervention. […] Regular imaging surveillance is critical after diagnosis and after aneurysm interventions. […] There are no effective preventive strategies for TAA to date; thus, early detection, surveillance, and treatment are critical to improving outcomes. Guidelines are available. […] Most cases of TAA are asymptomatic and are discovered either incidentally on imaging or as part of dedicated screening for those at risk.
- #85 Aortic aneurysms Screening, surveillance and referralhttps://www.racgp.org.au/afp/2013/june/aortic-aneurysms
Aortic aneurysms are a common finding in elderly patients. Rupture of an aortic aneurysm is a catastrophic event associated with a very high mortality. […] Screening of men aged 65 years and over has been shown to reduce aneurysm related mortality, however, no formal screening guidelines exist in Australia. In addition to the risk of aneurysm expansion and rupture, patients are at increased risk of cardiovascular morbidity and mortality. Small aneurysms should be managed with surveillance and cardiovascular risk factor modification. Large aneurysms should be referred promptly to a vascular surgeon for assessment and repair. […] Currently no formal AAA screening guidelines or programs exist in Australia, unlike Sweden, the United Kingdom and the United States. Screening with ultrasound in men over the age of 65 years has been demonstrated to reduce aneurysm related mortality in four large trials, including one performed in Western Australia.

On the basis of evidence showing substantial benefit, the US Preventive Services Task Force (USPSTF) recommends one-time ultrasonography screening for men aged 65-75 years who have ever smoked. […] The justification for screening programs has been further revisited by the publication of a 2017 meta-analysis of all reported trials, which concluded that screening reduces AAA-related deaths (odds ratio [OR] 0.66, 95% CI: 0.47, 0.93, P 0.02). […] While aortic aneurysm surveillance is generally recommended on the basis of maximal aortic diameter, it is recognised that this is merely a crude surrogate marker for rupture risk. […] Current research explores materials modelling, computational fluid dynamics and finite element analysis in order to predict how aneurysms will grow and the potential location and timing of rupture.

Yale Department of Surgerys Edouard Aboian, MD, evaluated abdominal aortic aneurysm surveillance in postoperative settings. […] We compared the standard for postoperative abdominal aortic aneurysm surveillance, maximum aortic diameter, to volumetric analysis of abdominal aortic aneurysm. […] The change of volume was more sensitive compared to diameter change, especially after endovascular abdominal aortic aneurysm repair. […] Our volumetric aneurysm analysis confers that you can detect that and potentially intervene early on. […] Volumetric evaluation has less interobserver variability compared to maximum diameter because diameter can be measured in different planes, oftentimes not orthogonal to the centerline of flow, and that may introduce some false findings in aortic aneurysm behavior. […] We are developing predictive clinical tools for a more sensitive analysis of aneurysm post intervention.

In 2019, WPR had the largest number of AAA cases, whereas AFR had the least. […] Similarly, the prevalence of AAA was the highest in the WPR, but the lowest in the AFR. […] Importantly, the relatively large number of AAA cases in AFR and EMR in the young-age to middle-age groups makes the 2 regions an important target for response. […] We also reaffirm the importance of smoking, male sex, and family history as leading risks of AAA globally, with the WPR the most affected region globally. […] We note a need to optimize epidemiological studies and existing structures for research in LMICs and resource-limited populations to promptly respond to at-risk and identified cases to improve outcomes.

The global ASDR increased from 0.12 (95% confidence interval 0.11, 0.14) in 1990 to 0.13 (0.11, 0.14) in 2021. […] The ASDR and ASDALYR for early-onset aortic aneurysm can be attributed to seven risk factors, categorized into four main groups: tobacco risks (smoking), dietary risks (low vegetable intake, low fruit intake, and high sodium intake), metabolic risks (high systolic blood pressure and high body-mass index), and environmental risks (lead exposure). Overall, smoking is the primary attributable risk factor for aortic aneurysm across all regions, time periods, and genders. […] The proportion of early-onset aortic aneurysm deaths attributable to smoking globally decreased from 41 to 39%. […] The burden of early-onset aortic aneurysm will continue to rise in the next 20 years, particularly in Asian and African regions. It is necessary to strengthen vascular health prevention strategies and aortic aneurysm management in these regions.
