A 26 year-old female presented with progressive intermittent right upper quadrant pain. Hepatic arteriovenous malformation with small intrahepatic bilomas were found. She underwent hepatic artery ligation for control of her abdominal pain. Though the abdominal pain subsided after the hepatic artery ligation, the intrahepatic bilomas progressed. It is possible that the hepatic arteriovenous malformation (AVM) might reduce blood flow to the bile duct and then induce ischemia in the peribiliary capillary plexus, thus leading to bile duct necrosis and formation of bilomas, which could be further aggravated by hepatic artery ligation.
