A branch of the common hepatic artery--the gastroduodenal artery gives off the small supraduodenal artery to the duodenal bulb . Then the right gastric artery comes off and runs to the left along the lesser curvature of the stomach to meet the left gastric artery, which is a branch of the celiac trunk . It subsequently bifurcates into the right and left hepatic arteries . Of note, the right and left hepatic arteries may demonstrate variant anatomy . A misplaced right hepatic artery may arise from the superior mesenteric artery (SMA) and a misplaced left hepatic artery may arise from the left gastric artery . The cystic artery generally comes from the right hepatic artery . </P>

When does the common hepatic artery become the proper hepatic artery
