[Obstructive jaundice due to compression of the common bile duct by right hepatic artery originated from gastroduodenal artery].

Obstructive jaundice by vascular compression is rare. The causative arteries were identified as the right hepatic artery, gastroduodenal artery, cystic artery, proper hepatic artery, and an unspecified branch of the common hepatic artery. Also the venous system, such as enlarging collateral veins in cases of portal hypertension was a causative vessel. Herein, we describe a case of a proximal choledocholithiasis due to compression of the common bile duct by right hepatic artery originated from gastroduodenal artery. Final diagnosis and treatment were achieved through an operation.
