title: [Rupture of a pancreaticoduodenal artery aneurysm into the common bile duct secondary to chronic pancreatitis: a case report].
abstract: A 57-year-old man with a history of excessive drinking presented to our emergency department complaining of chest discomfort. He had been attending a clinic for diabetes mellitus and hypertension, at which he had been informed that he had anemia that was worsening. Computed tomography (CT) of the abdomen revealed hemobilia and chronic pancreatitis. Due to complicated cholangitis, endoscopic nasobiliary drainage was performed, and a contrast-enhanced abdominal CT scan showed a pancreaticoduodenal aneurysm close to the common bile duct. We diagnosed a ruptured pancreaticoduodenal artery aneurysm causing hemobilia, and performed selective transcatheter arterial embolization with intravascular microcoils. Complete occlusion of the aneurysm was confirmed on follow-up CT.
