Abstract

Anatomical variations of the hepatic artery have been described as responsible for the onset of jaundice or stone formation. We present three cases of intrahepatic stones secondary to a compression of the proximal common bile duct (CBD) by the right hepatic artery (RHA). Three consecutive patients (males, mean age 65 years) with symptoms of cholangitis and intra-hepatic stones admitted between October 2017 and June 2018 with a final diagnosis of CBD compression from the RHA. The three patients underwent ERCP and biliary sphincterotomy with extraction of intra-hepatic stones; after stone removal cholangiograhy showed CBD compression just below the main hepatic confluence which was confirmed to be secondary to RHA compression on subsequent MRI. The patients remained asymptomatic after 12 months mean follow-up. Compression of the CBD by the RHA might be responsible for intra-hepatic stone formation. Endoscopic treatment is feasible and effective on short-term follow-up.
