Triple arterial blood supply to the liver and double cystic arteries.
A rare combination of variations in the arterial supply of the liver and gallbladder was encountered in a male cadaver. The simultaneous occurrence of an accessory left hepatic artery and an accessory right hepatic artery from which double cystic arteries arose (one of which was low-lying). This combination has not yet been reported. The accessory left hepatic artery originated from the left gastric artery. The accessory right hepatic artery originated from the superior mesenteric artery. Such arterial variations are caused by differences in embryological development. This, however, may lead to complications related to diagnostic and therapeutic procedures in the upper abdomen.
