These paper is an analyses of 110 patients who received abdominal aortography and selective organ angiographyfrom July 1977 to Aug. 1979 at the Dept. of Radiology of Yonsei Medical Center. 1. The most frequent site ofbifurcation of the abdominal aorta was the 4th intervertebral disc level, occuring in 22 of 50 cases (42.3%). 2.The celiac trunk arose most frequently at the level of the 12th thoracic intervertebral disc, occuring in 11 of 52cases (21.2%). 3. The superior mesentric arterly arose most frequent at the level of the upper third of the 1stlumbar vertebra, occuring in 8 of 30 cases (26.7%). 4. The right renal artery most frequently arose at the levelof the middle third of the 1st lumbar vertebra, occuring in 17 of 70 cases (24.3%) and the left renal arteryoccured most frequently in 1st lumbar vertebral disc level, 14 of 70 cases (20%). 5. Both renal arteries mostcommonly arose symmetrically as seen in 37 of 70 cases (52.6%). Case in which the right side arose at a higherlevel than the left occured in 28 of 70 cases (40.6%). 6. Accessory renal arteries occured in 19 of 70cases(27.1%). 7. The most common form of the celiac trunk in which it divides into left gastric, splenic andcommon hepatic arteries was seen in 30 of 38 cases (78.9%). 8. The normal hepatic artery pattern in which itarises from the common hepatic artery and divides into right, middle and left hepatic artery occured in 23 of 38cases (60.5%). A replaced right hepatic artery was seen in 2 of 35 cases (5.3%), and an accessory right hepaticartery also in 2 of 38 cases(5.3%).
