Rupture of a hepatic artery pseudoaneurysm (HAPA) can lead to life-threatening bleeding with a high mortality rate. The most common causes of hepatic artery pseudoaneurysms are trauma, pancreatitis, biliary and pancreatic surgery, and percutaneous biliary drainage. We reported a 77 year-old man with a HAPA rupture associated with a medical history of gastrotomy and pyloroplasty 15 years previously. He presented with severe upper abdomen pain and bloody ascites. Diagnosis was established by abdominal computed tomogrphy and celiac angiography. Transcatheter arterial embolization of HAPA was performed, via retrograde superselection of the common hepatic artery to stop bleeding.
