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.
