ABSTRACT

The liver has a highly variable vascular anatomy. In the classic vascularization pattern of the liver, the common hepatic artery, a branch of celiac trunk, divides into a right and left hepatic arteries to supply the respective lobes of the liver. The present article reports the origin of the right hepatic artery from the superior mesenteric artery that supply the gallbladder, common bile duct, the caudate and the right lobe of the liver during the routine anatomical dissection in an adult female cadaver. The artery had a close relation with pancreas, common bile duct and gall bladder in its course. The knowledge of the variation is essential for the surgeons and interventional radiologists while doing various procedures on liver, gall bladder and pancreas. The ignorance of the same can lead to intraoperative and postoperative complications including hepatic ischemia.

Keywords: Superior mesenteric artery, bile duct, right hepatic artery, liver, pancreas.
