A 75-year-old man with chronic cholangitis and a common bile duct stone that was not previously identified was admitted for right upper quadrant pain. Acute cholecystitis with cholangitis was suspected on abdominal computed tomography (CT); therefore, endoscopic retrograde cholangiopancreatography with endonasal biliary drainage was performed. On admission day 5, hemobilia with rupture of two intrahepatic artery pseudoaneurysms was observed on follow-up abdominal CT. Coil embolization of the pseudoaneurysms was conducted using percutaneous transhepatic biliary drainage. After several days, intrahepatic artery pseudoaneurysm rupture recurred and coil embolization through a percutaneous transhepatic biliary drainage tract was conducted after failure of embolization via the hepatic artery due to previous coiling. After the second coil embolization, a common bile duct stone was removed, and the patient presented no complications during 4 months of follow-up. We report a case of intrahepatic artery pseudoaneurysm rupture without prior history of intervention involving the hepatobiliary system that was successfully managed using coil embolization through percutaneous transhepatic biliary drainage.
