Abstract
A 60-year-old woman developed an infective endocarditis (IE) which involved the mitral valve. Treatment with antibiotics was effective. However, one month later, the patient presented with pain in the epigastric area. A superior mesenteric artery (SMA) aneurysm was diagnosed based on ultrasound and CT images. Since the patient had an excellent collateral circulation, direct suture of the SMA and a resection of the aneurysm were performed. The patient had no major complications postoperatively. Aneurysm of the SMA associated with infection is rarely seen. Patients with IE require careful follow-up.
