A Case of Hemobilia due to a Pseudoaneurysm Caused by a Pancreatic Pseudocyst

Abstract

Pseudoaneurysm is a rare but critical complication of pancreatic pseudocyst. A man in his 40's with abdominal pain was admitted to our hospital. Abdominal CT shows hemobilia due to a pseudoaneurysm caused by a pancreatic pseudocyst. Emergency angiography was performed and pseudoaneurysm was demonstrated in the gastroduodenal artery region. Transcatheter arterial embolization therapy was successfully performed with coils.
