Septic Embolic Occlusion of the Superior Mesenteric Artery Induced by Mitral Valve Endocarditis

抄録

A 75-year-old woman, who had been treated for rheumatic arthritis, was transferred to our hospital because of acute abdomen and continuous fever for several weeks. She had peritonitis, and abdominal computed tomography detected a thrombus occluding the proximal superior mesenteric artery and infarctions of the kidneys and spleen. Echocardiography showed a large vegetation on the anterior leaflet of the mitral valve. The necrotic small bowel and ascending colon were resected, and mitral valve replacement was performed 5 days later. She suffered from hyperbilirubinemia and pneumonia for several weeks after the operation but recovered successfully thereafter.
