Abstract

Peripheral mycotic aneurysm is a rare complication of infective endocarditis. We herein report the case of a 61-year-old man with a mycotic aneurysm in the left brachial artery, that appeared during treatment with antibiotics against infective endocarditis caused by Streptococcus sanguinis. After confirming the collateral blood flow on arteriography, we resected the aneurysm and performed valvuloplasty, annuloplasty and coronary artery bypass grafting. The patient has been in good condition without complications, such as motor dysfunction or neuropathy.
