Tętniak aorty piersiowej
Zapobieganie i profilaktyka
Tętniak aorty piersiowej (TAA) wymaga kompleksowej profilaktyki obejmującej modyfikację stylu życia, kontrolę chorób współistniejących oraz regularne badania przesiewowe. Kluczowe jest zaprzestanie palenia tytoniu, co zmniejsza ryzyko pęknięcia tętniaka aż 4-krotnie, umiarkowana aktywność fizyczna (minimum 30 minut dziennie), zdrowa dieta niskosodowa oraz kontrola masy ciała i spożycia alkoholu. W leczeniu farmakologicznym zaleca się utrzymanie ciśnienia tętniczego poniżej 130/80 mmHg za pomocą beta-blokerów oraz inhibitorów ACE lub ARB, a także stosowanie statyn w dawkach atorwastatyny 40-80 mg/d lub rosuwastatyny 20-40 mg/d. Wczesne wykrycie tętniaka u pacjentów z grup ryzyka (m.in. z zespołami genetycznymi, rodzinnym występowaniem, dwupłatkową zastawką aortalną) odbywa się za pomocą echokardiografii, tomografii komputerowej lub rezonansu magnetycznego, a monitorowanie powinno być wykonywane co 6-12 miesięcy w zależności od wielkości i dynamiki wzrostu tętniaka.

Profilaktyka tętniaka aorty piersiowej
Tętniak aorty piersiowej (TAA) stanowi poważne zagrożenie dla zdrowia i życia pacjentów z uwagi na ryzyko pęknięcia i rozwarstwiania aorty. Odpowiednia profilaktyka i wczesne wykrywanie tej choroby są kluczowe dla poprawy rokowania. Kompleksowe podejście do profilaktyki tętniaka aorty piersiowej obejmuje zarówno modyfikację stylu życia, jak i farmakoterapię, a także regularne badania przesiewowe u osób z podwyższonym ryzykiem wystąpienia tej choroby.12
Modyfikacja czynników ryzyka
Kluczowym elementem profilaktyki tętniaka aorty piersiowej jest modyfikacja czynników ryzyka poprzez prowadzenie zdrowego stylu życia. Odpowiednie działania prewencyjne mogą znacząco zmniejszyć ryzyko wystąpienia lub progresji tętniaka aorty piersiowej.12
- Zaprzestanie palenia tytoniu – palenie tytoniu jest głównym czynnikiem ryzyka rozwoju tętniaka aorty piersiowej. Pacjenci powinni być kierowani do programów rzucania palenia z użyciem terapii zastępczej nikotyny, warenikliny lub bupropionu. Zaprzestanie palenia może zmniejszyć ryzyko pęknięcia tętniaka aż 4-krotnie.12
- Regularna aktywność fizyczna – umiarkowana aktywność fizyczna minimum 30 minut dziennie, najlepiej przez większość dni w tygodniu, wspiera ogólne zdrowie układu sercowo-naczyniowego. Zalecane są ćwiczenia aerobowe, takie jak spacery, jazda na rowerze, pływanie czy lekki jogging. Pacjenci z rozpoznanym tętniakiem powinni jednak unikać intensywnego wysiłku fizycznego, podnoszenia ciężarów oraz aktywności, które wymagają napinania mięśni.12
- Zdrowa dieta – zaleca się dietę bogatą w owoce, warzywa, pełne ziarna, ryby i niskotłuszczowe produkty mleczne. Ograniczeniu powinno podlegać spożycie sodu, alkoholu i słodyczy. Dieta niskosolna pomaga obniżyć ciśnienie tętnicze, a ograniczenie tłuszczów nasyconych i cholesterolu może spowolnić rozwój miażdżycy, która jest częstym czynnikiem przyczyniającym się do powstawania tętniaków.12
- Utrzymanie prawidłowej masy ciała – nadwaga i otyłość zwiększają ryzyko nadciśnienia tętniczego i choroby wieńcowej, które z kolei mogą przyczyniać się do powstawania tętniaków aorty.1
- Ograniczenie spożycia alkoholu – nadmierne spożycie alkoholu prowadzi do nadciśnienia tętniczego i zwiększa ryzyko wystąpienia tętniaka aorty.1
- Zarządzanie stresem – zalecane są techniki redukcji stresu, takie jak joga, medytacja, mindfulness i poradnictwo psychologiczne. Stres przyczynia się do podwyższenia ciśnienia tętniczego, co może negatywnie wpływać na stan aorty.1
Kontrola chorób współistniejących
Odpowiednie leczenie chorób współistniejących ma kluczowe znaczenie w profilaktyce tętniaka aorty piersiowej:12
- Kontrola nadciśnienia tętniczego – nadciśnienie tętnicze jest głównym czynnikiem ryzyka rozwoju tętniaka aorty piersiowej i jego powikłań. Ciśnienie tętnicze u pacjentów z tętniakiem aorty piersiowej powinno być utrzymywane poniżej 130/80 mmHg. Zaleca się stosowanie beta-blokerów w połączeniu z inhibitorami konwertazy angiotensyny (ACE) lub blokerami receptora angiotensyny (ARB).12
- Leczenie dyslipidemii – u pacjentów z tętniakiem aorty piersiowej zaleca się stosowanie statyn w wysokich dawkach, takich jak atorwastatyna 40-80 mg dziennie lub rosuwastatyna 20-40 mg dziennie. Leczenie dyslipidemii pomaga zapobiegać progresji miażdżycy, która jest częstą przyczyną tętniaków aorty.1
- Kontrola cukrzycy – właściwe leczenie cukrzycy i utrzymywanie prawidłowego poziomu glukozy we krwi pomaga chronić naczynia krwionośne i zapobiegać rozwojowi miażdżycy.1
Badania przesiewowe i monitorowanie
Wczesne wykrycie tętniaka aorty piersiowej poprzez badania przesiewowe jest kluczowe dla skutecznej profilaktyki i leczenia. Regularne monitorowanie jest niezbędne zarówno u osób z podwyższonym ryzykiem, jak i u pacjentów z już zdiagnozowanym tętniakiem.12
Badania przesiewowe są szczególnie zalecane dla następujących grup pacjentów:12
- Osoby z rodzinnym występowaniem tętniaka aorty piersiowej
- Pacjenci z genetycznymi zespołami związanymi z tętniakami aorty piersiowej, takimi jak zespół Marfana, zespół Ehlersa-Danlosa czy zespół Loeysa-Dietza
- Pacjenci z dwupłatkową zastawką aortalną
- Krewni pierwszego stopnia pacjentów z tętniakiem aorty piersiowej (nawet do 20% pacjentów z tętniakiem może mieć pozytywny wywiad rodzinny)
- Kobiety z tętniakiem aorty piersiowej planujące ciążę
- Sportowcy podejmujący treningi siłowe z dużymi obciążeniami
Rekomendowane metody obrazowania w badaniach przesiewowych obejmują:12
- Echokardiografię przezklatkową (TTE)
- Tomografię komputerową (CT) lub angiografię CT (CTA)
- Rezonans magnetyczny (MRI) lub angiografię rezonansu magnetycznego (MRA)
Po zdiagnozowaniu tętniaka aorty piersiowej, częstotliwość badań kontrolnych powinna być dostosowana do wielkości tętniaka, szybkości jego wzrostu oraz czynników ryzyka pacjenta. Zazwyczaj zaleca się wykonywanie badań obrazowych co 6-12 miesięcy.12
Leczenie zapobiegawcze
Dla pacjentów z małym, bezobjawowym tętniakiem aorty piersiowej, leczenie zachowawcze opiera się na minimalizowaniu stresu na ścianie aorty i ograniczaniu dalszego powiększania się tętniaka.1
Farmakoterapia
Podstawą farmakoterapii w profilaktyce tętniaka aorty piersiowej jest:12
- Beta-blokery – zmniejszają częstość akcji serca, obniżają ciśnienie tętnicze i redukują siłę skurczu mięśnia sercowego, co zmniejsza napięcie ściany aorty. Mogą pomóc zapobiec lub spowolnić powiększanie się tętniaka oraz zmniejszyć ryzyko rozwarstwienia aorty.
- Inhibitory ACE lub ARB – zalecane w połączeniu z beta-blokerami dla optymalnej kontroli ciśnienia tętniczego.
- Statyny – atorwastatyna 40-80 mg dziennie lub rosuwastatyna 20-40 mg dziennie, które nie tylko obniżają poziom cholesterolu, ale mają także właściwości przeciwzapalne i mogą stabilizować blaszkę miażdżycową.
- Leki przeciwpłytkowe – mogą być rozważane w indywidualnych przypadkach, zwłaszcza u pacjentów z współistniejącą chorobą wieńcową.
- Antykoagulanty – mogą być stosowane w przypadku skrzepliny przyściennej w tętniaku aorty piersiowej, choć ich zastosowanie pozostaje kontrowersyjne u pacjentów bezobjawowych.
Profilaktyczna interwencja chirurgiczna
Profilaktyczne leczenie chirurgiczne lub wewnątrznaczyniowe tętniaka aorty piersiowej jest zalecane w następujących przypadkach:123
- Tętniaki objawowe, niezależnie od rozmiaru
- Tętniaki bezobjawowe o średnicy ≥5,5 cm u pacjentów z sporadycznym tętniakiem aorty piersiowej
- Tętniaki bezobjawowe o średnicy ≥5,0 cm u pacjentów z dziedzicznym tętniakiem aorty piersiowej (HTAD)
- Tętniaki o szybkim tempie wzrostu (>0,5-1,0 cm/rok)
- Tętniaki bezobjawowe o średnicy 5,0-5,5 cm u kobiet (ze względu na wyższe ryzyko pęknięcia przy mniejszych średnicach niż u mężczyzn)
Wybór metody leczenia (operacja otwarta lub wewnątrznaczyniowa) zależy od lokalizacji tętniaka, anatomii pacjenta, chorób współistniejących oraz doświadczenia zespołu leczącego.1
Zapobieganie powikłaniom podczas leczenia chirurgicznego
W przypadku leczenia chirurgicznego tętniaka aorty piersiowej, szczególnie istotne jest zapobieganie deficytom neurologicznym związanym z niedokrwieniem rdzenia kręgowego. Metody zapobiegania tym powikłaniom obejmują:123
- Drenaż płynu mózgowo-rdzeniowego (CSFD) – obniża ciśnienie wewnątrzczaszkowe płynu mózgowo-rdzeniowego, co może zmniejszyć ryzyko deficytu neurologicznego o 80%
- Utrzymanie odpowiedniego ciśnienia perfuzji rdzenia kręgowego (SCPP) – powinno wynosić co najmniej 60 mmHg
- Krążenie pozaustrojowe z hipotermią (LHB) – może zmniejszyć ryzyko deficytu neurologicznego o 63%
- Reimplantacja tętnic międzyżebrowych i lędźwiowych – szczególnie w regionie T7/8 do L1/2
- Właściwe postępowanie pooperacyjne – utrzymywanie odpowiedniego średniego ciśnienia tętniczego, odpowiednia resuscytacja objętościowa, zarządzanie drenażem płynu mózgowo-rdzeniowego oraz optymalne progi hemoglobiny
Edukacja pacjenta i wsparcie psychospołeczne
Kluczowym aspektem profilaktyki tętniaka aorty piersiowej jest odpowiednia edukacja pacjenta i jego rodziny oraz zapewnienie wsparcia psychospołecznego.12
- Przekazanie pacjentowi szczegółowych informacji na temat choroby, czynników ryzyka i metod profilaktyki
- Edukacja w zakresie rozpoznawania objawów pęknięcia lub rozwarstwienia tętniaka wymagających natychmiastowej pomocy medycznej
- Szkolenie dotyczące bezpiecznej aktywności fizycznej i ograniczeń w podnoszeniu ciężarów
- Porady dietetyczne i związane z zarządzaniem stresem
- Informacje o grupach wsparcia dla pacjentów z tętniakiem aorty
- Zachęcanie do regularnych wizyt kontrolnych i wykonywania zalecanych badań obrazowych
- Poradnictwo genetyczne dla pacjentów z rodzinnym występowaniem tętniaka aorty piersiowej
Programy przesiewowe dla krewnych pierwszego stopnia
Osoby z tętniakiem aorty piersiowej powinny informować swoich krewnych pierwszego stopnia o konieczności badań przesiewowych. Programy badań przesiewowych dla krewnych pierwszego stopnia powinny obejmować:12
- Obrazowanie aorty (echokardiografia, CT lub MRI)
- Ocenę opuszki aorty i aorty wstępującej
- Długoterminowy nadzór nad osobami z potwierdzonym ryzykiem
- W przypadku podejrzenia genetycznego podłoża tętniaka, konsultację genetyczną i ewentualne badania genetyczne
Znaczenie wielodyscyplinarnego podejścia
Optymalne postępowanie profilaktyczne w tętniaku aorty piersiowej wymaga wielodyscyplinarnego podejścia z udziałem kardiologów, chirurgów naczyniowych, genetyków klinicznych i innych specjalistów.12
Zespół wielodyscyplinarny powinien:1
- Dokonać dokładnej oceny pacjenta, uwzględniając czynniki genetyczne, anatomiczne i kliniczne
- Opracować indywidualny plan profilaktyki i leczenia
- Określić optymalną częstotliwość badań kontrolnych
- Ustalić próg średnicy aorty dla interwencji chirurgicznej w oparciu o indywidualne czynniki ryzyka
- Zapewnić kompleksową opiekę nad pacjentem i jego rodziną
Profilaktyka tętniaka aorty piersiowej jest procesem kompleksowym, wymagającym zaangażowania zarówno pacjenta, jak i zespołu medycznego. Dzięki wczesnemu wykrywaniu, modyfikacji czynników ryzyka, regularnej obserwacji i odpowiedniemu leczeniu, można znacząco zmniejszyć ryzyko powikłań i poprawić jakość życia pacjentów z tętniakiem aorty piersiowej.12

- #1 Thoracic aortic aneurysm: Optimal surveillance and treatment | Cleveland Clinic Journal of Medicinehttps://www.ccjm.org/content/87/9/557
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. […] There are no effective preventive strategies for TAA to date; thus, early detection, surveillance, and treatment are critical to improving outcomes. Guidelines are available. […] The need for prophylactic intervention is based on aneurysm size, location, growth, and other associated conditions and risk factors in the individual patient. Management strategies include surgery, which is mandatory in the acute setting and in cases of challenging anatomy, and endovascular techniques. Regular imaging surveillance is critical after diagnosis and after aneurysm interventions. […] Patients with thoracic aortic aneurysm require multidisciplinary care, including a cardiologist and possibly a cardiovascular surgeon and genetic counselor. […] Medical care includes traditional cardiovascular risk factor management. Beta-blockers are often used to control blood pressure but should be used with caution in those with acute aortic valve regurgitation.

- #1 Thoracic Aortic Aneurysms – Cardiovascular Disorders – Merck Manual Professional Editionhttps://www.merckmanuals.com/professional/cardiovascular-disorders/diseases-of-the-aorta-and-its-branches/thoracic-aortic-aneurysms
Most thoracic aortic aneurysms result from atherosclerosis. […] Risk factors for both thoracic aortic aneurysms and aortic dissections include prolonged hypertension, dyslipidemia, and smoking. Additional risk factors for TAAs include presence of aneurysms elsewhere in the body, infection, aortitis, and older age (peak incidence at age 65 to 70 years). […] Immediate control of hypertension is essential. Medical management with optimal control of hypertension, dyslipidemia, diabetes, and respiratory disease is the appropriate treatment until surgery is indicated. […] Asymptomatic aneurysms that do not meet criteria for elective surgical or endovascular repair are treated with aggressive blood pressure control using a beta-blocker and other antihypertensives if necessary. Smoking cessation is essential. Dyslipidemia, diabetes, and respiratory diseases should all be treated. […] Patients require frequent follow-ups to check for symptoms and serial CT or ultrasound every 6 to 12 months. Imaging frequency depends on aneurysm size.
- #1 Management of thoracic aortic aneurysm in adults – UpToDatehttps://www.uptodate.com/contents/management-of-thoracic-aortic-aneurysm-in-adults
Management of thoracic aortic aneurysm in adults […] Conservative management of asymptomatic TAA aims to lessen stress on the aorta and limit further aortic expansion. Asymptomatic patients who do not meet the criteria for repair also require ongoing aneurysm surveillance. […] For patients who meet the criteria for repair, survival is improved for open surgery compared with medical therapy alone. This should also be the case for endovascular repair, given that endovascular repair compares favorably with open surgery. Asymptomatic patients with TAA who do not meet the criteria for repair are managed medically with routine surveillance.
- #1 Prophylactic Surgery for Thoracic Aortic Aneurysmhttps://pmc.ncbi.nlm.nih.gov/articles/PMC10106997/
A 68-year-old man presented for evaluation of a 5.0-cm asymptomatic ascending aortic aneurysm. […] Given the possibility that his TAD might be heritable, the patient was advised to have his first-degree relatives screened with TTE or CTA to examine both the aortic root and ascending aorta. […] The typical threshold for prophylactic surgical replacement in cases of heritable TAD is an aortic diameter of 5.0 cm, as opposed to 5.5 cm for sporadic TAD. […] The optimal timing of prophylactic surgery to prevent potential aortic dissection or rupture depends heavily on the genetic context in which the aneurysm occurs, as heritable aneurysms tend to grow faster and dissect earlier. […] Because of the increased likelihood of these events among patients with HTAD compared to those with non-HTAD, they should be referred for prophylactic surgery at a maximal aortic diameter 5.0 cm.
- #1 Thoracic Aortic Aneurysms: At What Size Should We Intervene? – Endovascular Todayhttps://evtoday.com/articles/2017-nov/thoracic-aortic-aneurysms-at-what-size-should-we-intervene
Symptomatic aneurysms and aneurysms associated with a rapid growth rate of 1 cm per year should also be repaired because of an increased risk for rupture. […] Current guidelines for repair suggest the threshold for prophylactic surgical aortic repair to be within the range of 5.5 to 6 cm, but the decision regarding which individual will benefit from repair remains challenging. […] At present, it seems that there is no one-size-fits-all treatment, and therefore, patient selection should be performed on an individual basis according to morphological complexities, comorbidities, and anticipated overall survival and durability of any repair.
- #1 Current approaches to spinal cord protection during open thoracoabdominal aortic aneurysm repair – Coselli- Annals of Cardiothoracic Surgeryhttps://www.annalscts.com/article/view/17014/html
Spinal cord deficit (SCD) is a feared complication after thoracoabdominal aortic aneurysm repair. Vigilant management throughout the perioperative period is necessary to reduce the risk of SCD. Measures for preventing SCD during the intraoperative period include preoperative optimization and recognizing patients at a higher risk of SCD. […] If SCD is recognized early, therapeutic intervention may be implemented to mitigate injury. […] CSFD is a vital component of spinal cord protection that works by lowering intrathecal CSF pressure. Our group has shown in a randomized trial that the use of CSFD in extent I and II TAAA repairs resulted in an 80% relative risk reduction in the development of SCD. […] Currently, our CSFD use rates are as follows: extent I, 97%; extent II, 98%; extent III, 77%; extent IV, 36%.

[…] Our cardiology department embraces a holistic approach focused on and tailored to each patient, and the team is committed to high-quality care and patient safety, using leading-edge research to offer patients the latest treatments and clinical advice. […] If a patient is diagnosed with an aortic aneurism, it is important for them to notify family to potentially be screened for an aortic aneurysm as well. The First-Degree Relative program provides screening, imaging and long-term surveillance for those individuals who have a relative diagnosed with a thoracic aneurysm. […] Every patient in the Integrated Aortic Program receives an individualized treatment plan that includes managing risk factors such as high blood pressure and high cholesterol. Patients also receive personalized education on safe activities and lifting with an aneurysm. For most patients, regular surveillance combined with risk factor management is enough treatment to safely manage their aneurysm.
- #1 Thoracic Aortic Aneurysm & Aortic Dissection | Marfan Foundationhttps://marfan.org/conditions/familial-aortic-aneurysm/
Medications (drugs) that reduce the stress on the aorta can be helpful. Beta-blockers help lower blood pressure and reduce the force of the heartbeat. They also may help prevent or slow aortic enlargement and reduce the risk of aortic dissection. […] People with familial thoracic aortic aneurysm and dissection must have routine tests to monitor their aortic health and identify problems before there is an emergency. These are the same imaging tests that doctors use to diagnose the condition: echocardiogram, MRI, CT scan, or TEE. […] Surgery is most effective if it is done before an aortic dissection or other life-threatening situation. Surgery is considered when: The rate of enlargement of the ascending aorta approaches 0.5 cm per year; The diameter of the ascending aorta is between 4.2 and 5.0 cm (depending on the underlying mutation or family history). […] Regardless of which type of surgery is performed, patients must continue to take their blood pressure medicine and have their aorta monitored at least once a year to safeguard against additional enlargements or tears in other parts of the aorta.
- #1 Largest-ever study of thoracic aortic aneurysm supports treatment guidelines – Kaiser Permanente Division of Researchhttps://divisionofresearch.kaiserpermanente.org/taa-study-supports-guidelines/
A diagnosis of a thoracic aortic aneurysm a bulge in the part of the main artery that runs through the chest can be frightening. […] But a large, new Kaiser Permanente study provides high-quality evidence that most of the 33,000 patients diagnosed each year in the U.S. with a thoracic aortic aneurysm are not likely to experience a tear or rupture an aortic dissection and may not need open-heart surgery. […] The study, published October 5 in JAMA Cardiology, is the largest to date to support the current consensus guidelines that recommend surgery for most patients with a thoracic aneurysm that is 5.5 centimeters or larger. […] Our study shows that regular monitoring, coupled with aggressive blood pressure control and lifestyle changes, is a safe strategy for most patients until the aneurysm reaches the 5.5 centimeter mark, when surgery becomes necessary, said Solomon, who is the founder and director of the KPNC Center for Thoracic Aortic Disease. […] Patients absolutely need this surgery when surgical risk is less than the risk of dissection.

Management of thoracic aortic aneurysm in adults […] Conservative management of asymptomatic TAA aims to lessen stress on the aorta and limit further aortic expansion. Asymptomatic patients who do not meet the criteria for repair also require ongoing aneurysm surveillance. […] For patients who meet the criteria for repair, survival is improved for open surgery compared with medical therapy alone. This should also be the case for endovascular repair, given that endovascular repair compares favorably with open surgery. Asymptomatic patients with TAA who do not meet the criteria for repair are managed medically with routine surveillance.

Most thoracic aortic aneurysms result from atherosclerosis. […] Risk factors for both thoracic aortic aneurysms and aortic dissections include prolonged hypertension, dyslipidemia, and smoking. Additional risk factors for TAAs include presence of aneurysms elsewhere in the body, infection, aortitis, and older age (peak incidence at age 65 to 70 years). […] Immediate control of hypertension is essential. Medical management with optimal control of hypertension, dyslipidemia, diabetes, and respiratory disease is the appropriate treatment until surgery is indicated. […] Asymptomatic aneurysms that do not meet criteria for elective surgical or endovascular repair are treated with aggressive blood pressure control using a beta-blocker and other antihypertensives if necessary. Smoking cessation is essential. Dyslipidemia, diabetes, and respiratory diseases should all be treated. […] Patients require frequent follow-ups to check for symptoms and serial CT or ultrasound every 6 to 12 months. Imaging frequency depends on aneurysm size.

A 68-year-old man presented for evaluation of a 5.0-cm asymptomatic ascending aortic aneurysm. […] Given the possibility that his TAD might be heritable, the patient was advised to have his first-degree relatives screened with TTE or CTA to examine both the aortic root and ascending aorta. […] The typical threshold for prophylactic surgical replacement in cases of heritable TAD is an aortic diameter of 5.0 cm, as opposed to 5.5 cm for sporadic TAD. […] The optimal timing of prophylactic surgery to prevent potential aortic dissection or rupture depends heavily on the genetic context in which the aneurysm occurs, as heritable aneurysms tend to grow faster and dissect earlier. […] Because of the increased likelihood of these events among patients with HTAD compared to those with non-HTAD, they should be referred for prophylactic surgery at a maximal aortic diameter 5.0 cm.

Medications (drugs) that reduce the stress on the aorta can be helpful. Beta-blockers help lower blood pressure and reduce the force of the heartbeat. They also may help prevent or slow aortic enlargement and reduce the risk of aortic dissection. […] People with familial thoracic aortic aneurysm and dissection must have routine tests to monitor their aortic health and identify problems before there is an emergency. These are the same imaging tests that doctors use to diagnose the condition: echocardiogram, MRI, CT scan, or TEE. […] Surgery is most effective if it is done before an aortic dissection or other life-threatening situation. Surgery is considered when: The rate of enlargement of the ascending aorta approaches 0.5 cm per year; The diameter of the ascending aorta is between 4.2 and 5.0 cm (depending on the underlying mutation or family history). […] Regardless of which type of surgery is performed, patients must continue to take their blood pressure medicine and have their aorta monitored at least once a year to safeguard against additional enlargements or tears in other parts of the aorta.

Thoracic aortic aneurysm (TAA) is a potentially life-threatening disorder that without intervention carries a poor prognosis. […] Maximum aortic diameter is the key parameter used to predict rupture risk and is therefore central in directing clinicians whether to offer surveillance or surgical repair. […] Based on these findings, the authors suggested the threshold of 5.5 to 6 cm for prophylactic surgical aortic repair. […] The 2017 European Society for Vascular and Endovascular Surgery (ESVS) guidelines on descending thoracic aortic disease suggested that endovascular repair should be considered for descending TAAs 60 mm diameter, as this is the diameter where risk of rupture sharply escalates (classification IIa, level B evidence). […] The latest ESVS guidelines suggest that based on the size differential between men and women at baseline, the threshold can be reduced to 50 to 55 mm for women.

A critical element of preventing SCD is maintaining an adequate spinal cord perfusion pressure (SCPP), which is equal to the spinal arterial pressure minus the venous pressure. […] The goal is to maintain an SCPP that is at least 60 mmHg because values below that are associated with a higher SCD risk. […] The role of LHB was established in a retrospective study that showed an associated 63% relative risk reduction in SCD for patients undergoing extent II repair. […] In a recent series of patients from our center, LHB was used in 45% of TAAA repairs with a mean duration of 25 minutes. […] Typically, the intercostal and lumbar arteries are aggressively reimplanted in the T7/8 to L1/2 region and revascularized. […] RILA has been shown to be an independent predictor of reduced persistent and delayed SCD, cutting the SCD risk by about half.

Certain high-risk features of HTAD may prompt the consideration of an earlier intervention. […] In cases of sporadic TAD, first-degree relatives should undergo screening aortic imaging, as up to 20% of patients with root or ascending aortic aneurysms may have a positive family history of TAD. […] The management of thoracic aortic aneurysm and the appropriate timing of prophylactic surgical aortic replacement to prevent potential dissection or rupture require careful characterization of the genetic risk factors for each patient.

A thoracic aortic aneurysm is an enlargement of the aorta (the main blood vessel that carries blood away from the heart to the rest of the body) in the thoracic cavity or the chest area. This condition is fairly common in the general population, but about 20 percent of the cases are caused by a genetic condition. […] Early detection, frequent imaging, and treatment are critical because both aortic aneurysms and dissections increase the risk that the aorta will suddenly burst (rupture), causing massive internal bleeding. Without surgery to prevent aortic rupture, these blood vessel abnormalities can be life-threatening. […] The management of familial thoracic aortic aneurysm and/or dissection requires the coordinated input from a multidisciplinary team of specialists familiar with this condition, including a medical geneticist, cardiologist, and cardiovascular surgeon.

Quit smoking. According to the Centers for Disease Control and Prevention (CDC), a history of smoking accounts for about 75% of all abdominal aortic aneurysms. […] Stay active. Exercise, even simply walking, can improve the health of your arteries and heart. […] Maintain a healthy blood pressure. High blood pressure increases your risk of worsening aortic aneurysm. […] Control your cholesterol intake. Eat a heart-healthy diet by avoiding foods with high cholesterol, like beef, whole milk, baked goods, and fried foods. […] Medication can help improve your symptoms and prevent your aneurysm from getting worse. […] While there are possible risks to aortic aneurysm repair, your doctor may recommend surgery depending on the size of your aneurysm and how quickly it’s growing. […] Types of surgery for aortic aneurysm are: […] If you have an aortic aneurysm, it’s important to know the signs of a rupture. Getting treatment as quickly as possible may save your life. […] While all aneurysms are potentially serious, following your treatment plan can help you manage your symptoms and keep the condition from getting worse.

Symptomatic aneurysms and aneurysms associated with a rapid growth rate of 1 cm per year should also be repaired because of an increased risk for rupture. […] Current guidelines for repair suggest the threshold for prophylactic surgical aortic repair to be within the range of 5.5 to 6 cm, but the decision regarding which individual will benefit from repair remains challenging. […] At present, it seems that there is no one-size-fits-all treatment, and therefore, patient selection should be performed on an individual basis according to morphological complexities, comorbidities, and anticipated overall survival and durability of any repair.

Postoperative management after TAAA repair must complement the operative procedure. General guiding principles include maintaining a satisfactory MAP with adequate volume resuscitation and cardiac index, CSFD management, optimal hemoglobin thresholds, adequate oxygenation in the early postoperative period to ensure adequate spinal cord oxygen delivery, and careful multidisciplinary critical care. […] Delayed paraplegia is defined as SCD that develops later in the postoperative period after the patient has awakened from anesthesia appearing neurologically intact after TAAA repair. […] Our current approach to delayed paraplegia is outlined in Figure 3. […] TAAA repair is associated with a significant risk of SCD. Over the course of several decades, multiple surgical adjuncts and strategies have been developed that have reduced the risk of SCD substantially when performed by experienced surgeons and teams.
