AbstractA 52-year-old woman with a 3-week history of fever and cough was diagnosed as having bacterial endocarditis with vegetation and severe mitral valve insufficiency by echocardiography. Blood culture revealed Streptococcus mitis. After antibiotic treatment for 3 weeks, the patient noticed swelling with pain in her left groin. Computed tomography revealed an occluded aneurysm in the left common femoral artery. Simultaneous surgical treatments of mitral valve replacement and bypass grafting using a saphenous vein following resection of the mycotic femoral arterial aneurysm were performed. Pathohistological examination of surgical specimens revealed acute inflammatory findings, but no microorganisms were found, probably because of the preoperative antibiotic therapy. Her postoperative course was uneventful, and there was no recurrence of mycotic aneurysms in a period of 10 months after the operation. Prompt recognition and urgent simultaneous surgical treatments for mycotic aneurysms complicated with infective endocarditis were effective.
