SUMMARY

The purpose of this study was to determine the different variants of celiac and superior mesenteric arteries identified at abdominal 64-slice CT scanner performed in 910 patients.

Results: 282 patients (30.9%) had arterial variants identified. The most common variant identified was a right hepatic artery originating from the superior mesenteric artery, which was seen in 77 (8.5%) patients. The second most common variant was a left hepatic artery originating from the left gastric artery, seen in 47 (5.2%) patients. Variations in the origin of the common hepatic artery were seen in 10 (1.1%) patients. The right hepatic artery originated from the celiac axis in 13 (1.4%) patients and from the aorta in 3 (0.3%) patient. The left hepatic artery originated from the celiac axis in 4 (0.4%) patient.
