Considerations in the management of aneurysms of the superior mesenteric artery

Aneurysms of the superior mesenteric artery (SMA) are rare, accounting for 5.5% of all splanchnic aneurysms and <0.5% of all intraabdominal aneurysms. Previous reports have characterized these aneurysms among splanchnic arter y aneurysms. However, these aneurysms are quite different in terms of etiol ogy, presentation, and treatment, and their independent consideration is wa rranted. We report a patient with a traumatic SMA aneurysms who was success fully treated with surgical resection and distal revascularization. We also present an alternative technique of retrograde aorto-SMA bypass using auto logous vein that prevents kinking. Also included is a review of the recent literature as it pertains specifically to SMA aneurysms. DOI:10.1007/s10016 9910074.
