title: Accessory right hepatic artery branched from gastroduodenal artery.
abstract: The right hepatic artery usually branches from the common hepatic artery, however, there are cases showing anatomic variations. We present 41-year-old female patient with gallbladder cancer. In this case, the accessory right hepatic artery branched from the gastroduodenal artery, passed in front of the common bile duct and fed into the anterior segment of the liver. Cholecystectomy and resection of the extrahepatic bile duct with hepaticoenterostomy were performed successfully, preserving the accessory right hepatic artery. There are few reports presenting such an extremely rare anomaly of hepatic arteries in the English literature. Additionally, we herein present a review of the English literature regarding anatomic variations of right hepatic artery.
