Vascular variations in and around the porta hepatis are common. A sound knowledge of possible variations at these sites is vital for surgeons during laparoscopic cholecystectomy and surgical resection of the liver lobes. We report the case of several variations of the hepatic and cystic arteries in which, the common hepatic artery trifurcated into the gastroduodenal, right hepatic, and left hepatic arteries. The right gastric artery arose from the left hepatic artery and divided into a left and a right branch. The left branch entered the liver through the porta hepatis, while the right branch passed behind the common hepatic duct into the Calot's triangle, provided 2 branches to the gallbladder, and continued to supply the right hepatic lobe. Ligation of the right branch of the right hepatic artery in Calot's triangle during cholecystectomy could cause avascular necrosis of the liver segments it supplies.
