A Case of a Ruptured Aneurysm of the Anterior Inferior Pacreaticoduodenal Artery

Abstract

We report a case of a ruptured aneurysm of the anterior inferior pancreaticoduodenal artery. A 70-year-old man was referred to our hospital because of loss of consciousness. Plain computed tomography (CT) revealed no lesions in the head, and the patient returned home. Five hours later, he visited our hospital again complaining of increasing abdominal pain, and was admitted with a diagnosis of acute peritonitis. Enhanced abdominal CT showed a retroperitoneal hematoma, 15×12×5cm in size, with an extravasation around the head of the pancreas. As the patient had developed circulatory shock, emergency angiography was performed, revealing a ruptured aneurysm of the anterior inferior pancreaticoduodenal artery. He was successfully treated with transcatheter arterial embolization using platinum micro -coils.
