Abstract

The aim of this study was to evaluate the variation which based on Celiac axis and SMA using by CT volume rendering images. 613 patients underwent abdominal CTA, there were 552 patients (99.05%, TypeI, II) with normal anatomical form and 61 (9.95%, Type III~XII) with variation. TypeI was 339(55.31%), Type II was 213 (34.74%), Type III was 18 (2.93%), Type IV was 12 patients (1.95%), Type V was 11 patient (1.79%), Type VI was 9 patients (1.46%), Type VII was 6 patients (0.97%), Type VIII was 1 patient (0.16%), Type IX was 1 patient (0.16%), Type X was 1 patient (0.16%), Type XI was 1 patient (0.16%), and Type XII was 1 patient (0.16%) into totally new types of variation. In conclusion, we could found 9 new types of variation by classifying based on celiac axis and superior mesenteric artery. These results were considered to be an important opportunity for a new vessel map.

복부 전산화단층촬영 후 3차원 볼륨렌더링으로 재구성한 영상을 분석하여 복부대동맥에서 분지하는 복강축과 위창자간막동맥을 기준으로 해부학적 변위를 분류하여 평가하고자 하였다. 복부 전산화단층혈관촬영을 시행한 613명 환자의 3차원 볼륨렌더링 영상을 이용하여 해부학적 변위를 형태별로 분류한 결과 552명(Type I, II)은 정상 구조에 속하였고, 61명(Type III~XII)은 변위로 분류하였다. Type I이 339명 (55.31%), Type II가 213명(34.74%)으로 나타났으며 변위로 분류된 경우는 Type III은 18명(2.93%), Type IV는 12명 (1.95%), Type V는 11명 (1.79%), Type VI는 9명 (1.46%), Type VII는 6명 (0.97%)으로 나타났으며, Type VIII~XII는 각각 1명 (0.16%)으로 전혀 새로운 변위형태로 분류되었다. 결론적으로 복강축과 위창자간막동맥을 기준으로 변위를 분류한 결과 그동안 간동맥 중심의 해부학적 변위 분류에서는 관찰되지 않았던 9가지의 새로운 변위형태를 파악할 수 있었다. 이는 새로운 혈류지도를 만드는 중요한 자료로 이용될 수 있을 것으로 사료된다.
