A Pseudoaneurysm of Superior Mesenteric Artery: Successfully Treated by Aorto-Mesenteric Bypass: A case report

ABSTRACT

Aneurysms of superior mesenteric artery (SMA) represent an uncommon but important vascular disease. High mortality rates from rupture of aneurysm and thrombosis of SMA are reported. These lesions are most often infectious in etiology. In the case of relatively abundant collaterals, aneurysm exclusion or SMA ligation is a safe surgical method to prevent serious complications. But in insufficient collaterals, stent-grafting of aneurysm or reconstruction of mesenteric blood flow is unavoidable. Recently we treated a 49-year-old man with SMA pseudoaneurysm and its large orifice located at near the enlarged jejunal branch which is a main collateral of mesenteric blood flow.
