Abstract

Aneurysmal disease of visceral arteries is found in only 0.2% of the general population. Aneurysms that involve the splenic artery account for more than 60% of all visceral aneurysms8,10). The hepatic artery is involved in 20%, whereas the celiac trunk is involved in 4.5% and the superior mesenteric artery in 5.5%. The remaining 10% include those of the branches of the superior mesenteric artery, the gastroduodenal, the pancreaticoduodenal arteries and the inferior mesenteric artery(5,13)). The etiology of visceral aneurysms include atherosclerosis, medial degeneration, infection, fibromuscular dysplasia, dissection and congenital anomalies(2,12,13)). The size and anatomic location of the aneurysm should be considered to determine the correct surgical treatment. The authors report a case of aneurysmal dissection of the superior mesenteric artery in a 56-year-old male patient who had acute abdominal pain and massive melena. Resection of dissecting aneurysm and PTFE interposition was performed, and post-operative course was uneventful.
