Abstract

Aneurysms of the superior mesenteric artery are rare, accounting for 8% of visceral artery aneurysms. About 60% of all superior mesenteric artery aneurysms have a mycotic origin. The only helpful clinical manifestations are episodes of previous abdominal pain and a history of valvular heart disease. In this case, a 66-year-old female patient with mitral regurgitation and aortic regurgitation presented with pain in the upper abdominal area. A superior mesenteric artery aneurysm was diagnosed at the time of impending rupture. Since excellent collateral circulation was present, an aneurysmectomy without revascularization was performed, and no ischemic symptom occurred. The patient presented no major complications during the postoperative course.
