A 31-year-old man underwent mitral valve replacement because of mitral regurgitation due to continued active infective endocarditis despite antibiotic therapy. Because cerebral mycotic aneurysm was suggested by preoperative IVDSA (Intravenous Digital Subtraction Angiography), cerebral angiography was performed on the first postoperative day. Cerebral mycotic aneurysm was detected in the middle cerebral artery and emergency aneurysm trapping was successfully performed. Although the patient had no neurologic deficit and postoperative cardiac function was stable, impending rupture of the mycotic aneurysm of the superior mesenteric artery occurred suddenly on the twelfth postoperative day. Endovascular treatment using the coil-embolization technique was immediately performed, and the postoperative course was uneventful.
