Visceral artery pseudoaneurysms following pancreatoduodenectomy

Abstract

Pancreatic and biliary fistulas and delayed gastric emptying are the most common complications after pancreatoduodenectomy. The development and bleeding of visceral arterial pseudoaneurysms are rare phenomena and pose diagnostic and treatment dilemmas. We describe 5 recent patients who developed bleeding from visceral artery pseudoaneurysms after pancreatoduodenectomy. These patients all had "herald" bleeding from their abdominal drains. Subsequent angiography and therapeutic embolizations were successfully performed.
