Superior mesenteric artery aneurysm secondary to infectious endocarditis.

A case of superior mesenteric artery aneurysm secondary to infectious endocarditis is presented. Although selective angiography was necessary to detect the shape and precise location of the aneurysm, non-invasive diagnostic techniques including ultrasonography and computed tomography were also useful in detecting the aneurysm and planning the management of this unusual condition. Mitral valve replacement and aneurysmorrhaphy with bypass grafting of the superior mesenteric artery were successfully performed.
