Pseudoaneurysm of cystic artery with upper gastrointestinal hemorrhage.

Pseudoaneurysms of the pancreaticoduodenal arteries commonly occur in pancreatitis. Pseudoaneurysms of the hepatic artery and its branches usually occur due to trauma. I report a pseudoaneurysm of the cystic artery resulting from cholecystitis and successful surgical treatment of the pseudoaneurysm.
