We present herein two cases of a ruptured aneurysm of the visceral artery.
The first case involved a 74-yeal-old man with abdominal pain who was admit
ted to our hospital with a tentative diagnosis of intra-abdominal bleeding
of unknown origin. Computed tomography revealed a hematoma in the greater c
urvature of the stomach. At surgery, a hematoma along the right gastroepipl
oic artery was found and totally removed. Histological examination showed a
pseudo-aneurysm of unknown etiology. The second case involved a 68-year-ol
d man with progressive anemia who presented with spontaneous intra-abdomina
l bleeding. A ruptured aneurysm of the accessory middle colic artery was di
agnosed by superior mesenteric angiography. The ruptured aneurysm was ligat
ed and totally resected without a colectomy. Histological examination showe
d a pseudoaneurysm of unknown etiology. The postoperative courses were unev
entful, and both patients were doing well at the time of writing.
