Abstract

Giriş:

Çalışmamızın amacı, abdominal çok kesitli bilgisayarlı tomografi (ÇKBT) incelemesi yapılan hasta popülasyonunda çölyak arter(ÇA), süperior mezenterik arter(SMA) ve renal arter (RA) anatomisindeki varyasyonları saptamaktır.

Gereç ve Yöntem:

Çeşitli nedenlerle abdominal ÇKBT incelemesi yapılan toplam 100 hasta geriye dönük olarak değerlendirilerek ÇA, SMA ve RA varyasyonlarının sıklığı araştırılmıştır.

Bulgular:

100 vakanın 80’inde (%80) normal ÇA anatomisi izlenmiştir. En sık rastlanan ÇA varyasyonu gastro-splenik trunkus (%12) olarak saptanmıştır. Normal SMA, 100 olgunun 83’ünde gözlendi. SMA'nın en sık varyasyonu 12 olgu (%12) ile SMA'dan orjin alan replase sağ hepatik arterdir. İki yüz böbrekten

177 böbrekte (%84) tek ana RA normal dallanma paterni varken, bunlardan 9 (%4.5) böbrekte erken dallanma gözlendi. Ekstrarenal RA ise 23 (%11.5) böbrekte gözlendi. Bu 21 böbrekte aksesuar (%10.5) hiler arter mevcutken, 2 tanesinde superior polar arter (%1) izlendi.

Sonuç:

ÇKBT anjiyografi abdominal vasküler anatomi ve varyasyonların değerlendirilmesinde kullanılacak oldukça güvenilir, invaziv olmayan ve günümüzde rahat ulaşılabilir bir görüntüleme metodudur.

Anatomic Variations of Abdominal Aorta

Abstract

Aim:

The aim of this study was to determine the ratio of variations observed in the anatomy of the celiac artery( CA), superior mesenteric artery(SMA), and renal artery (RA) by screening a patient population who underwent abdominal multi-detector computed tomography angiography.

Materials and Methods:

A total of 100 patients who underwent abdominal multi-detector computed tomography angiography

for various reasons were analyzed retrospectively and the prevalence of the variations observed in the CA, SMA, and RA were determined.

Results:

A normal anatomy of the celiac artery was determined in 80 of the 100 cases (80%).The most common CA variation was gastro-splenic trunk (12%). We determined normal SMA anatomy in 83 of the total 100 cases (83%). The most common variation of SMA was a replaced right hepatic artery originating from the SMA in 12 cases (12%). While a single RA with normal branching pattern was observed in 177 kidneys (% 84) in 200 kidneys, early branching of RA was observed in 9 (4.5%) kidneys. Extrarenal RA was observed in 23 (11.5%) kidney. Twenty-one of extrarenal RA (10.5%) were a hilar artery and 2(%1) of these were superior polar artery.

Conclusion:

Multi-detector computed tomography angiography is a highly reliable, noninvasive imaging method for the evaluation of abdominal vascular anatomy and its variations.
