Anatomical variations in the arterial supply of liver

The knowledge about the anatomical variations in the arterial supply of liver is mandatory for surgeons. Presence of hepatic arterial variations may lead to surgical injuries in the liver which can be made inadvertently even by the most experienced surgeons. During the routine dissection of a 70-year-old male cadaver, the following variations were observed: Right hepatic artery taking origin as replaced right hepatic artery from superior mesenteric artery; in addition to normal left hepatic artery, an accessory left hepatic artery arising from left gastric artery; middle hepatic artery (artery to quadrate lobe) that usually arises from right or left hepatic artery, in the present case was found to arise from gastroduodenal artery. These aberrant arteries have embryological and clinical significance.
