title: Ruptured aneurysm of the visceral artery: report of two cases.
abstract: We present herein two cases of a ruptured aneurysm of the visceral artery. The first case involved a 74-year-old man with abdominal pain who was admitted to our hospital with a tentative diagnosis of intra-abdominal bleeding of unknown origin. Computed tomography revealed a hematoma in the greater curvature of the stomach. At surgery, a hematoma along the right gastroepiploic artery was found and totally removed. Histological examination showed a pseudo-aneurysm of unknown etiology. The second case involved a 68-year-old man with progressive anemia who presented with spontaneous intra-abdominal bleeding. A ruptured aneurysm of the accessory middle colic artery was diagnosed by superior mesenteric angiography. The ruptured aneurysm was ligated and totally resected without a colectomy. Histological examination showed a pseudoaneurysm of unknown etiology. The postoperative courses were uneventful, and both patients were doing well at the time of writing.
