Tętniak
Diagnostyka i diagnoza

Tętniak definiowany jest jako miejscowe uwypuklenie ściany tętnicy, najczęściej lokalizujące się w aorcie brzusznej (średnica ≥3 cm), aorcie piersiowej oraz tętnicach mózgowych. Diagnostyka opiera się na badaniach obrazowych: USG (czułość ~95%, specyficzność bliska 100% dla tętniaków aorty brzusznej), TK z angiografią (CTA) – złoty standard przedoperacyjny, MR/MRA jako alternatywa dla pacjentów z przeciwwskazaniami do CTA oraz angiografii cyfrowej (DSA) – złoty standard w diagnostyce tętniaków mózgowych. W przypadku podejrzenia pęknięcia tętniaka mózgu, gdy TK jest negatywne, wskazane jest nakłucie lędźwiowe w celu wykrycia krwawienia podpajęczynówkowego. Diagnostyka laboratoryjna obejmuje morfologię, badania układu krzepnięcia oraz biochemię, a także monitorowanie zmian w EKG po pęknięciu tętniaka mózgu. Badania przesiewowe USG aorty brzusznej rekomendowane są u mężczyzn 65-75 lat z historią palenia tytoniu lub innymi czynnikami ryzyka, a także u kobiet z historią palenia i krewnych pacjentów z tętniakiem.

Tętniak – Diagnostyka i Rozpoznanie

Tętniak to miejscowe uwypuklenie ściany tętnicy, które występuje na skutek jej osłabienia. Mogą formować się w dowolnych naczyniach krwionośnych w organizmie, jednak najczęściej spotykane są w aorcie brzusznej, aorcie piersiowej oraz w tętnicach mózgowych. Prawidłowa i wczesna diagnostyka tętniaków ma kluczowe znaczenie, ponieważ pęknięcie tętniaka może prowadzić do zagrażającego życiu krwawienia wewnętrznego.123

Przypadkowe Wykrycie Tętniaków

Większość tętniaków pozostaje bezobjawowa do momentu pęknięcia, co powoduje, że ich wczesne rozpoznanie bywa trudne. Często tętniaki są wykrywane przypadkowo podczas badań obrazowych wykonywanych z powodu innych schorzeń.123 Badania te mogą obejmować rutynowe prześwietlenia, badania ultrasonograficzne czy tomografię komputerową. W niektórych przypadkach tętniaki mogą zostać wykryte podczas zabiegu chirurgicznego.4

Badanie Fizykalne

W przypadku tętniaków aorty brzusznej lekarz może czasem wyczuć pulsującą masę w jamie brzusznej podczas badania palpacyjnego. Przy osłuchiwaniu jamy brzusznej stetoskopem może być słyszalny charakterystyczny szmer przepływu krwi. Należy jednak podkreślić, że tętniaki często nie mogą być wykryte wyłącznie na podstawie badania fizykalnego.123

Metody Diagnostyczne w Rozpoznawaniu Tętniaków

Badania Obrazowe

Diagnostyka obrazowa stanowi podstawę rozpoznawania tętniaków. Dostępne są różne metody, które różnią się czułością, specyficznością oraz szczegółowością uzyskiwanych obrazów:123

Badanie Ultrasonograficzne (USG)

USG jest najczęściej stosowanym badaniem w diagnostyce tętniaków aorty brzusznej. Jest to metoda nieinwazyjna, bezpieczna, stosunkowo tania i szeroko dostępna.12 Badanie to wykorzystuje fale dźwiękowe do utworzenia obrazów struktur wewnątrz ciała, umożliwiając:3

  • Wykrycie obecności tętniaka i określenie jego wielkości12
  • Monitorowanie wzrostu tętniaka w czasie3
  • Obserwację przepływu krwi przy użyciu ultrasonografii duplex4

Badanie USG ma czułość około 95% i specyficzność bliską 100% w wykrywaniu tętniaków aorty brzusznej, gdy jest wykonywane przez doświadczonego specjalistę.12

Tomografia Komputerowa (TK)

Badanie TK dostarcza bardziej szczegółowych obrazów niż USG i jest szczególnie przydatne w ocenie tętniaków przed planowanym leczeniem zabiegowym.12 TK wykorzystuje promieniowanie rentgenowskie do utworzenia przekrojowych obrazów ciała. Angiografia TK (CTA) dodatkowo wykorzystuje kontrast podawany dożylnie, co pozwala uwidocznić naczynia krwionośne.12 CTA umożliwia:3

  • Dokładne określenie wielkości, kształtu i lokalizacji tętniaka12
  • Ocenę stosunku tętniaka do ważnych struktur anatomicznych (np. tętnic nerkowych)3
  • Planowanie leczenia zabiegowego4
  • Monitorowanie po leczeniu zabiegowym5

CTA jest uznawane za złoty standard w przedoperacyjnej ocenie tętniaków aorty brzusznej i jest metodą z wyboru, jeśli pozwala na to czynność nerek.12

Rezonans Magnetyczny (MR)

MR jest alternatywną metodą obrazowania tętniaków, która nie wykorzystuje promieniowania rentgenowskiego.12 Angiografia rezonansu magnetycznego (MRA) pozwala na uwidocznienie naczyń krwionośnych dzięki zastosowaniu pola magnetycznego i fal radiowych.1 MR/MRA umożliwiają:2

  • Dokładną ocenę wielkości, kształtu i lokalizacji tętniaka12
  • Obrazowanie bez narażenia na promieniowanie jonizujące1
  • Alternatywę dla pacjentów z przeciwwskazaniami do CTA (np. alergią na jod)2
Angiografia

Angiografia (arteriografia) jest inwazyjnym badaniem, które polega na wprowadzeniu cewnika do tętnicy (najczęściej przez tętnicę w pachwinie lub ramieniu) i podaniu kontrastu, który uwidacznia naczynia krwionośne w obrazie rentgenowskim.12 Jest to najbardziej precyzyjna metoda diagnostyczna, ale ze względu na inwazyjny charakter jest rzadziej stosowana jako pierwsze badanie diagnostyczne.1

Angiografia cyfrowa z odejmowaniem (DSA) jest uważana za złoty standard w diagnostyce tętniaków mózgowych.12 Pozwala ona na:3

  • Precyzyjną ocenę wielkości, kształtu i relacji tętniaka do naczyń macierzystych1
  • Planowanie i przeprowadzenie leczenia wewnątrznaczyniowego (embolizacji)2
  • Możliwość trójwymiarowej rekonstrukcji obrazu (angiografia rotacyjna 3D)3

Badania Dodatkowe w Diagnostyce Tętniaków

Nakłucie Lędźwiowe (Punkcja Lędźwiowa)

W przypadku podejrzenia pękniętego tętniaka mózgu, gdy badanie TK nie wykazuje krwawienia, może być konieczne wykonanie nakłucia lędźwiowego.12 Badanie to polega na pobraniu płynu mózgowo-rdzeniowego do analizy:34

  • Obecność krwi w płynie mózgowo-rdzeniowym świadczy o krwawieniu podpajęczynówkowym1
  • Ksantochromia (żółte zabarwienie) supernatantu jest charakterystyczna dla krwawienia podpajęczynówkowego z pękniętego tętniaka12
Badania Laboratoryjne

W diagnostyce tętniaków, szczególnie w przypadku podejrzenia pęknięcia, wykonuje się także badania laboratoryjne:1

  • Morfologia krwi z płytkami – monitorowanie stanu zapalnego, ocena niedokrwistości i ryzyka krwawienia1
  • Badania układu krzepnięcia (PT/APTT) – identyfikacja koagulopatii zwiększającej ryzyko krwawienia1
  • Badania biochemiczne krwi – ocena stanu pacjenta i przygotowanie do ewentualnego leczenia1
Elektrokardiogram (EKG)

W przypadku tętniaków, szczególnie po pęknięciu tętniaka mózgu, mogą wystąpić zmiany w EKG, takie jak:1

  • Spiczaste załamki P1
  • Wydłużenie odstępu QT1
  • Wysokie załamki T1

Diagnostyka Specyficznych Rodzajów Tętniaków

Tętniak Aorty Brzusznej (TAB)

Tętniak aorty brzusznej definiuje się jako poszerzenie aorty brzusznej o średnicy co najmniej 3 cm.12 Diagnostyka TAB obejmuje:34

  • Badanie USG jamy brzusznej – podstawowa metoda diagnostyczna, stosowana również w badaniach przesiewowych12
  • CTA – stosowana do dokładnej oceny wielkości, kształtu i stosunku tętniaka do innych struktur anatomicznych przed planowanym leczeniem1
  • MRA – alternatywa dla CTA, szczególnie u pacjentów z przeciwwskazaniami do badania TK1

Tętniak aorty brzusznej jest rozpoznawany, gdy średnica aorty brzusznej wynosi 3 cm lub więcej.12

Tętniak Mózgu (Tętniak Wewnątrzczaszkowy)

Tętniak mózgu to uwypuklenie ściany tętnicy mózgowej.12 Diagnostyka obejmuje:34

  • TK bez kontrastu – podstawowa metoda w przypadku podejrzenia pęknięcia tętniaka i krwawienia podpajęczynówkowego12
  • CTA lub MRA – nieinwazyjne metody diagnostyczne pozwalające na lokalizację tętniaka i ocenę jego cech morfologicznych12
  • Angiografia cyfrowa (DSA) – złoty standard diagnostyczny, pozwalający na precyzyjną ocenę tętniaka i planowanie leczenia12
  • Nakłucie lędźwiowe – w przypadku podejrzenia krwawienia podpajęczynówkowego przy negatywnym wyniku TK12

Nowsze technologie diagnostyczne w rozpoznawaniu tętniaków mózgu obejmują:12

  • NOVA (Noninvasive Optimal Vessel Analysis) MRA – zaawansowana technologia umożliwiająca lepsze obrazowanie naczyń mózgowych1
  • Sztuczna inteligencja – wspomaga wykrywanie i monitorowanie tętniaków mózgu12

Tętniak Trzewny

Tętniaki tętnic trzewnych (VAAs) są rzadkim, ale poważnym schorzeniem, gdyż ich pęknięcie wiąże się z wysoką śmiertelnością.1 W ich diagnostyce stosuje się:2

  • CTA – podstawowa metoda diagnostyczna12
  • Angiografia – złoty standard diagnostyczny1

Tętniak Rzekomy (Pseudotętniak)

Pseudotętniak to fałszywy tętniak, powstający na skutek uszkodzenia ściany naczynia krwionośnego, najczęściej w wyniku urazu lub zabiegu chirurgicznego.1 Diagnostyka obejmuje:1

  • Badanie USG z wykorzystaniem techniki duplex1
  • CTA lub MRA1
  • Angiografia – w przypadkach wątpliwych lub w celu jednoczesnego leczenia1

Badania Przesiewowe w Kierunku Tętniaków

Badania przesiewowe są zalecane dla osób z grup zwiększonego ryzyka, ponieważ wczesne wykrycie tętniaka może zapobiec jego pęknięciu.12

Badania Przesiewowe w Kierunku Tętniaka Aorty Brzusznej

U.S. Preventive Services Task Force zaleca jednorazowe badanie przesiewowe USG w kierunku tętniaka aorty brzusznej dla:123

  • Mężczyzn w wieku 65-75 lat, którzy kiedykolwiek palili tytoń (co najmniej 100 papierosów w ciągu życia)12
  • Mężczyzn w wieku 65-75 lat, którzy nigdy nie palili, ale mają inne czynniki ryzyka (np. wywiad rodzinny)1

Society for Vascular Surgery rozszerza te zalecenia również na:1

  • Kobiety w wieku 65-75 lat z historią palenia tytoniu1
  • Osoby powyżej 75 roku życia w dobrym stanie zdrowia z historią palenia tytoniu, które wcześniej nie były badane1
  • Krewnych pierwszego stopnia pacjentów z tętniakiem aorty brzusznej w wieku 65-75 lat lub starszych w dobrym stanie zdrowia1

Badania Przesiewowe w Kierunku Tętniaka Mózgu

Badania przesiewowe w kierunku tętniaka mózgu są zalecane dla osób z wysokim ryzykiem:12

  • Osoby z wielotorbielowatością nerek12
  • Osoby z silnym wywiadem rodzinnym (co najmniej 2 krewnych pierwszego stopnia) tętniaków wewnątrzczaszkowych lub krwawienia podpajęczynówkowego12

American Heart Association i American Stroke Association zalecają badania przesiewowe z wykorzystaniem CTA lub MRA u osób z co najmniej dwoma krewnymi pierwszego stopnia, którzy przebyli krwawienie podpajęczynówkowe lub mieli niepęknięte tętniaki wewnątrzczaszkowe.1

Ocena Ryzyka Pęknięcia Tętniaka

Jednym z najważniejszych celów diagnostyki tętniaków jest ocena ryzyka ich pęknięcia, które porównuje się z ryzykiem związanym z leczeniem zabiegowym.1 Czynniki ryzyka pęknięcia obejmują:23

Tętniak Aorty Brzusznej – Ryzyko Pęknięcia

Czynniki wpływające na ryzyko pęknięcia tętniaka aorty brzusznej to:12

  • Wielkość tętniaka – główny czynnik prognostyczny; ryzyko pęknięcia wzrasta wraz ze wzrostem średnicy12
  • Tempo wzrostu tętniaka – szybki wzrost (>0,5-1 cm/rok) zwiększa ryzyko pęknięcia12
  • Nadciśnienie tętnicze – zwiększa nacisk na ścianę tętniaka1
  • Palenie tytoniu – przyspiesza wzrost tętniaka o około 0,4 mm/rok1
  • Obecność objawów – ból brzucha lub pleców może wskazywać na niestabilność tętniaka1

Powszechnie przyjmuje się, że leczenie zabiegowe tętniaka aorty brzusznej jest wskazane, gdy jego średnica osiąga 5,5 cm lub więcej u mężczyzn i 5,0 cm lub więcej u kobiet.1

Tętniak Mózgu – Ryzyko Pęknięcia

Czynniki wpływające na ryzyko pęknięcia tętniaka mózgu obejmują:12

  • Wielkość tętniaka – większe tętniaki mają wyższe ryzyko pęknięcia1
  • Lokalizacja tętniaka – niektóre lokalizacje wiążą się z wyższym ryzykiem pęknięcia1
  • Kształt tętniaka – nieregularny kształt lub obecność wypukleń zwiększa ryzyko1
  • Obecność objawów – bóle głowy, deficyty neurologiczne1
  • Wywiad poprzedniego krwawienia podpajęczynówkowego1

Monitorowanie Tętniaków

Tętniaki, które nie kwalifikują się do natychmiastowego leczenia zabiegowego, wymagają regularnego monitorowania w celu oceny tempa wzrostu i ewentualnych zmian morfologicznych.12

Tętniak Aorty Brzusznej – Monitorowanie

Zalecenia dotyczące częstości wykonywania badań kontrolnych:12

  • Tętniaki o średnicy 3,0-3,9 cm: badanie USG co 2-3 lata1
  • Tętniaki o średnicy 4,0-4,9 cm: badanie USG co 6-12 miesięcy1
  • Tętniaki o średnicy 5,0-5,4 cm: badanie USG co 3-6 miesięcy lub rozważenie leczenia zabiegowego1
  • Tętniaki szybko rosnące (>0,5-1 cm/rok) lub o średnicy ≥5,5 cm: rozważenie leczenia zabiegowego12

Tętniak Mózgu – Monitorowanie

Niepęknięte tętniaki mózgu, które nie wymagają natychmiastowego leczenia, są monitorowane przy użyciu badań obrazowych:12

  • MRA lub CTA w regularnych odstępach czasu (najczęściej co 6-12 miesięcy)1
  • Ocena wielkości, kształtu i ewentualnych zmian morfologicznych tętniaka1

Podsumowanie Diagnostyki Tętniaków

Prawidłowa diagnostyka tętniaków jest kluczowa dla podjęcia właściwych decyzji terapeutycznych i zapobiegania powikłaniom. Wybór metody diagnostycznej zależy od lokalizacji podejrzewanego tętniaka, dostępności badań oraz indywidualnych cech pacjenta.12

Standardowy algorytm diagnostyczny obejmuje:1

  • Badanie podmiotowe i przedmiotowe12
  • Badania obrazowe: USG, TK/CTA, MR/MRA, angiografia – dobierane indywidualnie12
  • Ocenę ryzyka pęknięcia tętniaka na podstawie jego cech morfologicznych i czynników klinicznych1
  • Ustalenie planu leczenia lub monitorowania12

Właściwe rozpoznanie i ocena tętniaka pozwalają na podjęcie odpowiednich działań terapeutycznych, które mogą obejmować obserwację, leczenie farmakologiczne lub zabiegowe, w zależności od indywidualnej sytuacji klinicznej pacjenta.12

  • #1 Aneurysm: What It Is, Types, Symptoms, Diagnosis & Treatment
    https://my.clevelandclinic.org/health/diseases/22769-aneurysm
    An aneurysm is a bulge in the wall of an artery. Aneurysms form when theres a weak area in the artery wall. Untreated aneurysms can burst open, leading to internal bleeding. They can also cause blood clots that block the flow of blood in your artery. Depending on the location of the aneurysm, a rupture or clot can be life-threatening. […] If you have symptoms that may indicate an aneurysm, your provider will do imaging tests. Imaging tests that can find and help diagnose an aneurysm include: CT scan, CT or MRI angiography, Ultrasound. […] If your provider discovers that you have an unruptured aneurysm, they’ll monitor your condition closely. The goal of treatment is to prevent the aneurysm from bursting. […] Healthcare providers usually can help you manage smaller, unruptured aneurysms. Your provider will monitor your condition closely. Medication or surgery can minimize the risk of rupture. […] An aneurysm can occur in any of the arteries in your body. Your provider can monitor and treat an aneurysm to reduce the risk of it bursting. If an aneurysm does rupture, its a medical emergency. You need to seek medical attention immediately.

    https://www.healthinaging.org/a-z-topic/aneurysms/tests
    There are a number of tests that can help diagnose an aneurysm. […] When the healthcare provider presses on the abdomen during a physical examination, they may be able to feel an abdominal aortic aneurysm. They may also hear a telltale rushing sound in the abdomen with a stethoscope. However, aneurysms often cant be found during a physical exam. Depending on symptoms, the healthcare provider may recommend other tests. […] Health care providers sometimes discover silent aneurysms (without symptoms) during surgery. They may also find one during a test, such as an x-ray, ultrasound, scan, that happens for another reason. […] This test uses sound waves to create a picture of the inside of the body. It can show an aneurysm and its size. […] This test uses x-rays to take pictures of internal organs. The technician will inject dye into a vein that will show up on the x-ray images. This shows the aneurysms size and shape. A CT scan gives a more detailed image than an ultrasound.

    https://www.mayoclinic.org/diseases-conditions/brain-aneurysm/diagnosis-treatment/drc-20361595
    Screening tests and procedures used to detect and diagnose brain aneurysms include: […] A CT angiogram can create detailed images of the arteries providing blood flow in the brain. The test involves injecting dye into the vein that makes it easier to observe blood flow. It also can detect the presence of an aneurysm. […] If you have symptoms of a ruptured aneurysm but a CT scan doesn’t show evidence of bleeding, a test of your cerebrospinal fluid can help make a diagnosis. […] A type of MRI that captures images of the arteries in detail is called MR angiography. This type of MRI can detect the size, shape and location of an aneurysm. […] A cerebral angiogram also called a cerebral arteriogram is usually used when other diagnostic tests don’t provide enough information. […] Screening for unruptured brain aneurysms is typically only used if you are at high risk.

  • #1 Abdominal Aortic Aneurysm | AAFP
    https://www.aafp.org/pubs/afp/issues/2015/0415/p538.html
    A ruptured AAA is a medical emergency associated with high mortality rates. The classic syndrome is characterized by hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. This triad may be incomplete or absent, and misdiagnosis can occur in up to 60% of cases. Therefore, physicians must be mindful of atypical presentations and attentive to new-onset, nonspecific back or abdominal pain in patients at risk of AAA. […] Because AAA is most often clinically silent, screening can improve detection. Ultrasonography has a high sensitivity and specificity (95% and nearly 100%, respectively) for detecting AAA when performed in a setting experienced in the use of ultrasonography. […] The main benefit of screening is decreased AAA-related mortality. […] The USPSTF continues to recommend one-time screening with ultrasonography for men 65 to 75 years of age with a history of smoking (level B recommendation).
  • #1 Abdominal Aortic Aneurysm (AAA) – Diagnosis and Treatment
    https://www.radiologyinfo.org/en/info/abdoaneurysm
    Abdominal aortic aneurysm (AAA) occurs when atherosclerosis or plaque buildup causes the walls of the abdominal aorta to become weak and bulge outward like a balloon. […] Your doctor can confirm the presence of an AAA with an abdominal ultrasound, abdominal and pelvic CT or angiography. […] Many abdominal aortic aneurysms are incidentally found on ultrasound examinations, x-rays or CT scans. […] To confirm the presence of an abdominal aortic aneurysm, a physician may order imaging tests including: Abdominal Ultrasound (US): Ultrasound is a highly accurate way to measure the size of an aneurysm. […] Abdominal and pelvic computed tomography (CT): This exam is highly accurate in determining the size and extent of an aneurysm. […] Angiography: This exam, which uses x-rays, CT or MRI and a contrast material to produce pictures of major blood vessels throughout the body, is used to help identify abnormalities such as abdominal aortic aneurysms.

    https://www.escardio.org/Journals/E-Journal-of-Cardiology-Practice/Volume-18/non-invasive-techniques-in-diagnosis-and-treatment-of-patients-with-abdominal-ao
    CT and MRI have emerged as the current gold standards in the preoperative and postoperative evaluation of AAA. […] Operator proficiency and availability of equipment may determine the preferred modality. […] CTA plays a key role in assessing the extent of disease because it provides a complete data set of the entire aorta (including the thoracic aorta) and access vessels. […] The preoperative assessment of AAA includes the measurement of the maximal transverse perpendicular diameter of the aneurysm and its relationship to the renal arteries. […] Although there is no randomised study on the best imaging modality, the consensus is that CTA, including multiplanar and curved 3D vascular reconstructions, is the preferred preoperative imaging modality, if permitted by renal function. […] In patients with AAA, the European Society for Vascular Surgery (ESVS) 2019 Clinical Practice Guidelines recommended a CTA for therapeutic decision making and treatment planning, and for the diagnosis of rupture.
  • #1 Diagnosis and Screening – Brain Aneurysm Foundation
    https://www.bafound.org/understanding-brain-aneurysms/warning-signs-symptoms/diagnosis-and-screening/
    For aneurysm screening, magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA) are preferred, using radio waves and a magnetic field without exposing patients to X-rays. […] CTA, MRA, or angiograms are also employed for diagnosing unruptured aneurysms. […] Misdiagnosis of brain aneurysms occur in up to one quarter of patients when initially seeking medical attention.
  • #1 Aortic Aneurysm – Diagnosis | NHLBI, NIH
    https://www.nhlbi.nih.gov/health/aortic-aneurysm/diagnosis
    To diagnose an aortic aneurysm, your healthcare provider will do a physical exam and an imaging test. An abdominal aortic aneurysm is diagnosed when your abdominal aorta is three centimeters or greater in diameter. […] Screening for aortic aneurysm is usually done using ultrasound. This test shows if the diameter of your aorta is bigger than it should be. If it is larger than normal, your provider may recommend another screening later to check for growth. […] To make the diagnosis your provider may order some tests. […] Ultrasound provides information about the size of the abdominal aortic aneurysm and monitors the aorta over time. […] MRI provides information about the size, shape, and location of the aneurysm.

    https://www.ohsu.edu/brain-institute/brain-aneurysm-diagnosis-and-treatment
    The OHSU Brain Institute is a national leader in diagnosing and treating brain aneurysms. […] Tests to check for a brain aneurysm include: […] Angiograms are used to find aneurysms and to see their size and shape. […] Cerebral angiogram: This uses advanced X-ray imaging to guide a catheter (thin plastic tube) through a leg artery to the brain. […] This is the definitive way to diagnose aneurysms. […] Your care team will customize your treatment based on factors such as: […] For small aneurysms without symptoms, your care team may recommend lifestyle changes. […] For larger aneurysms or those with symptoms, clipping or coiling may be recommended. […] A neurosurgeon temporarily removes a small section of skull (craniotomy) to reach the aneurysm. […] In this minimally invasive procedure, a doctor fills the aneurysm with tiny platinum coils, sealing it off from the artery. […] OHSU neurointerventionalists were the first on the West Coast to use a pipeline embolization device, or PED, to treat wide-neck aneurysms.
  • #1 Cerebral Aneurysm Workup: Laboratory Studies, Imaging Studies, Other Tests
    https://emedicine.medscape.com/article/1161518-workup
    Guidelines from the American Heart Association and American Stroke Association recommend screening with CTA or MRA in individuals with two or more first-degree relatives who had SAH or unruptured intracranial aneurysms. […] Aneurysmal SAH may be detected in 90-95% of cases. If CT scan result is negative and SAH is suspected, perform lumbar puncture (LP). […] CTA may detect aneurysms greater than 3 mm, providing detailed evaluation of morphology such as relationship to the parent vessel and neck width. […] Conventional angiography is the definitive procedure for the detection and characterization of cerebral aneurysms. Aneurysm location, size, and morphology may be evaluated in the acute or chronic setting with this modality. […] Further refinements in the characterization of cerebral aneurysms are expected following the recent introduction of 3-dimensional rotational angiography. Recent work has demonstrated that this technique may offer superior resolution and increased sensitivity for detection of small aneurysms.

    https://emedicine.medscape.com/article/1161518-workup
    Other tests that may be helpful for diagnosis include the following: ECG: Cardiac arrhythmias and myocardial ischemia may be evident. Aneurysmal SAH may be associated with several ECG changes, including peaked P waves, prolonged QT interval, and tall T waves. […] LP may help to establish the diagnosis of SAH in the absence of focal signs of mass effects. Aneurysmal SAH demonstrates hemorrhagic CSF with a xanthochromic supernatant, although these findings may be absent within the first few hours following aneurysmal rupture. […] Gross pathologic examination may reveal brownish pigmentation and fibrous adhesions of surrounding brain parenchyma. Aneurysm size may be diminished on postmortem examination, although a multilobular shape may be appreciated. A ruptured fundus may be visualized with calcifications of the aneurysm wall and intraluminal thrombus. […] Microscopic examination reveals defects in the normal architecture of the vessel wall. The tunica media and internal elastic lamina may be absent or degenerated, with hemosiderin-laden phagocytes and lymphocytic infiltration.
  • #1 Cerebral Aneurysm Workup: Laboratory Studies, Imaging Studies, Other Tests
    https://emedicine.medscape.com/article/1161518-workup
    Laboratory Studies: Lab studies that may be helpful for diagnosis include the following: CBC with platelets: Monitor for infection, evaluate anemia, and identify bleeding risk. Prothrombin time (PT)/activated partial thromboplastin time (aPTT): Identify a coagulopathy that increases bleeding risk. Serum chemistries, including electrolytes and osmolarity: Obtain baseline studies to monitor hyponatremia, address arrhythmogenic abnormalities, assess blood glucose, and monitor hyperosmolar therapy for elevated intracranial pressure. Liver function tests: Identify hepatic dysfunction that may complicate clinical course. Arterial blood gases: Assess blood oxygenation. […] Advances in neuroimaging techniques have altered the diagnosis of cerebral aneurysms dramatically. Noninvasive angiographic methods, such as computed tomographic angiography (CTA) and magnetic resonance angiography (MRA), allow for detection and characterization of aneurysms, further enhanced by postprocessing techniques that enable 3-dimensional evaluation of aneurysm morphology.

    An abdominal aortic aneurysm (AAA) is at least 3 cm in diameter. There is general agreement that AAAs with a diameter of 5.5 cm or greater in males and 5.0 cm or greater in females should undergo prophylactic repair. […] In the United States, 15,000 deaths per year are attributed to abdominal aortic aneurysms. AAAs occur most commonly in individuals between 65 and 75 years of age. […] Ruptured aneurysms are associated with a very high mortality, ranging from 50 to 95%, and mortality increases by 1% with each subsequent minute, necessitating prompt diagnosis and intervention. […] Abdominal aortic aneurysm repair is undertaken in men with an aneurysm of 5.5 cm or more and in women with an aneurysm of 5.0 cm or more.

    Aneurysmal subarachnoid haemorrhage (aSAH) presents a challenge to clinicians because of its multisystem effects. […] The critical care of aSAH prioritises cerebral perfusion, early aneurysm securement, and the prevention of secondary brain injury and systemic complications. […] Standardised neurological assessments, transcranial doppler (TCD), and advanced imaging, along with hypertensive and invasive therapies, are vital in reducing delayed cerebral ischemia and poor outcomes. […] Early interventions to mitigate cardiopulmonary complications, dyselectrolytemia and treatment of culprit aneurysm require a multidisciplinary approach. […] A non-contrast CT scan of the head (CTH), usually modern third-generation CTH, is 100% specific and highly sensitive for aSAH if scanned in the first 6h of headache onset.

    Through imaging screening techniques, individuals at high risk of harboring a brain aneurysm can be identified easily with non-invasive imaging tests. An aneurysm is often diagnosed using a variety of imaging equipment. Some methods include CT Scan, CTA, MRI and MRA. […] When a ruptured aneurysm is suspected, a head CT scan is performed to detect brain bleeding, using non-invasive X-ray technology. However, this scan typically does not reveal the aneurysm’s cause. […] To pinpoint aneurysms, doctors may employ computerized tomography angiography (CTA), injecting contrast dye to highlight brain blood vessels for specialized imaging. Alternatively, an angiogram may be necessary for clearer views, involving a catheter inserted into the groin artery to inject contrast dye and capture X-ray images.

    Brain aneurysms are focal dilations in the cerebral arteries. […] Diagnosis of aneurysms requires angiography, CT angiography, or magnetic resonance angiography. Catheter-based digital subtraction angiography (DSA) is the gold standard for diagnosing aneurysms. […] Before rupture, aneurysms occasionally cause sentinel (warning) headaches; actual rupture causes a sudden severe headache (thunderclap headache). […] Diagnose using angiography, CT angiography, or magnetic resonance angiography. […] If the aneurysm has ruptured, use digital subtraction angiography to locate the aneurysm, then proceed with endovascular therapy or open surgery.

    The aim of postoperative imaging is to predict or detect complications. […] Early (within 30 days) postoperative follow-up imaging after endovascular aortic repair is required to assess the success of the intervention, and reliable aneurysm exclusion, to detect presence of an endoleak, and component overlaps, and to assess the sealing zone length. […] An endoleak signifies the presence of flow in the aneurysm sac outside the graft after EVAR. […] There are five types of endoleak depending on the origin of the leak. […] Current recommendations regarding regular follow-up suggest up to five CT examinations during the first postoperative year. […] Current recommendations regarding screening, planning treatment and follow-up of patients with AAA are summarised in Figure 2. […] Ultrasonography has rapidly evolved into a cost-effective approach for aneurysm screening while computed tomography is the method of choice when considering a potential therapeutic intervention and for follow-up after AAA repair.
