Large aneurysm of the superior mesenteric artery

This report describes a rare case involving a large aneurysm of the superior mesenteric artery (S.M.A.) in a 53-year-old female. Diagnosis was made by X-ray and echography and confirmed by CT-scan and arteriography showing the lesion to be atherosclerotic in origin with several thrombi on the wall of the artery. Resection of the aneurysm and venous reconstruction was performed. Recovery was uneventful. Angiography one month later demonstrated patency of the bypass. At six months the patient is presently asymptomatic.
