Abstract:
Liver transplantation is the only solution for end-stage liver diseases. The common hepatic artery (CHA) arises from the coeliac trunk (CT), and the right (RHA) and left hepatic (LHA) arteries are its terminal branches. An abnormal arterial pattern would influence the surgical outcome. The anterior layer of the lesser omentum of a female cadaver was cleaned to identify the CHA, which was traced backwards for its origin and toward the porta hepatis for its terminal branches. In this case, the replaced RHA originated from the CT and ran posterior to the portal vein and the common bile duct. The replaced LHA arose from the left gastric artery. The CHA originated from the CT and branched out as the middle hepatic and gastroduodenal arteries. The replaced RHA and LHA with alteration in relation to the neighbouring structures is a complex and rare variant. Knowledge of this uncommon arterial anomaly is beneficial for hepatobiliary surgeons.
