Imaging Procedures and Findings
Aortogram and selective SMA arteriogram depict right hepatic artery originating from SMA.
The common hepatic artery arises from the celiac trunk. The gastroduodenal artery (GDA) is its first major branch, with the artery continuing as the proper hepatic artery. Branch arteries parallel the portal veins and supply the liver segments. In approximately 55% of people, the right, left, and middle hepatic arteries arise from the common hepatic artery. The cystic artery often arises from the right posterior branch. The middle hepatic artery may arise from either the left or right hepatic artery. It supplies liver segments IVa and IVb. In approximately 2.5% of people the common hepatic artery arises from the superior mesenteric artery. An aberrant right hepatic artery exists in up to 26% of people. The most common variations are either a replaced right hepatic artery or an accessory artery arising from the superior mesenteric artery (SMA). An aberrant left hepatic artery exists in up to 25% of people. The left hepatic artery may arise from the left gastric artery (15%) or from the gastroduodenol artery, splenic artery, or aorta in 4% of cases.
