False Aneurysm of the Peroneal Artery: An Unusual Complication of Femoro-Peroneal Bypass Grafting

Abstract

Non-traumatic false aneurysm formation involving the native crural vessels is rare. We present the case of a false aneurysm of the native peroneal artery, which complicated femoro-peroneal bypass grafting. It seemed most likely to be of an infective aetiology, arising as a consequence of contiguous methicillin resistant Staphylococcus aureus wound infection. This was previously unreported in the literature. Successful management was achieved by primary suture, local wound debridement, excision of the distal graft and replacement with an interposition vein graft through uninfected tissue planes.
