Abstract

Aims: The abdominal aorta (AA) plays a crucial role in both invasive and non-invasive radiological procedures, particularly in hepatorenal and colorectal surgeries. In this study, the abdominal aorta was examined morphologically, and the presence of aneurysms and accompanying pathologies was discussed. Anatomical structures that can guide surgeons and radiologists were defined as landmarks, and a morphometric approach was made. Methods: This study examined the AA of 20 formalin-embalmed American cadavers (ages 50-96) donated to Albert Einstein College of Medicine’s C&DA Department. From supine cadavers, aortic bifurcation (BA) levels were examined for the vertebral column. Linear, longitudinal, and transverse distances were measured between the Left renal artery (LtRA) and branching points of BA, diameters of AA, tortuosity, and morphology were examined. Results: Four of the 20 cadavers included in the study had AA aneurysm (AAA). Cadaveric examinations showed aortic dilatation, abdominal aorta wall thickness, atherosclerosis, thrombus formation at the Superior Mesenteric Artery (SMA), an abdominal tortuous aorta, L3 vertebrae deviation, multiple AAA, hemivertebrae, L3 compression fractures, and osteodegenerative changes. The average AA transverse diameter is 22.93±2.69 mm. Upon assessment of the correlation between advancing age and the incidence of AAA in the male population, no statistically significant relationship was found (p=0.167). Conclusion: Although the exact role of atherosclerosis in the development of AAA remains unclear, it may contribute to their occurrence; studies with larger cohorts are needed to better understand their prevalence and associated anatomical changes.

Özet

Amaç: Abdominal aort ve abdominal bölgedeki cerrahiler, özellikle hepatorenal ve kolorektal bölgeleri ilgilendirenler, hem invaziv hem de noninvaziv radyolojik prosedürlerde kritik öneme sahiptir. Bu çalışmada abdominal aort morfolojik olarak incelendi ve anevrizma varlığı ve eşlik eden patolojiler tartışıldı. Cerrahlara ve radyologlara rehberlik edebilecek anatomik yapılar landmark olarak tanımlandı ve morfometrik bir yaklaşım yapıldı. Yöntem: Bu çalışmada Albert Einstein College of Medicine C&DA Bölümü'ne bağışlanan 20 formalinle fikse Amerikan kadavrasının (yaşları 50-96) abdominal aorta(AA) incelendi. Supin pozisyondaki kadavralardan, vertebral kolon için aort bifurkasyon (BA) seviyeleri columna vertebralis’e göre değerlendirildi. Sol renal arter (LtRA) ile BA'nın dallanma noktaları arasındaki doğrusal, uzunlamasına ve enine mesafeler ölçüldü, AA çapları, kıvrımlılık ve morfoloji incelendi. Bulgular: Çalışmaya alınan 20 kadavranın dördünde AAA saptandı. Kadavra incelemelerinde aort dılatasyonu, abdominal aort duvar kalınlığı artışı, ateroskleroz, Superior Mezenterik Arter'de (SMA) trombüs oluşumu, abdominal kıvrımlı aort, L3 vertebra deviasyonu, çoklu AAA, hemivertebra, L3 kompresyon kırıkları ve osteodejeneratif değişiklikler görüldü. Ortalama AA transvers çapı 22,93±2,69 mm'dir. Erkek popülasyonunda ilerleyen yaş ile AAA insidansı arasındaki korelasyon değerlendirildiğinde p=0,167 olarak belirlendi. Sonuç: Bulgularımız, aterosklerotik arter duvarı bozulmasının özellikle AA'da anevrizmalara neden olduğu fikrini desteklemektedir. Ateroskleroz, abdominal aort anevrizmalarının ana nedeni olmayabilir, ancak prevalansa katkıda bulunabilir. Daha büyük kohortları içeren araştırmalar, erkeklerde abdominal aort anevrizmalarının yaygınlığını ve ilişkili anatomik yapılarda meydana gelen değişiklikleri açıklığa kavuşturacaktır.
