Vacuum-assisted closure therapy for salvaging a methicillin-resistant Staphylococcus aureus-infected prosthetic graft

Abstract

Infection of a vascular prosthesis after a bypass surgery is relatively rare. However, once developed, serious complications can occur, such as bleeding, sepsis, and organ ischemia, occasionally resulting in leg amputation or even death in some cases. The treatment of a vascular prosthesis infection involves the necessary removal of the infected graft; subsequently, an extra-anatomical bypass surgery is often considered. We herein report a case in which postoperative methicillin-resistant Staphylococcus aureus infection caused dehiscence of the femoral vessels and exposure of the graft vessel and anastomosed area. The infected tissue was surgically removed (debridement), and the patient's condition was successfully treated by the application of a nonadherent dressing and vacuum-assisted closure therapy combined with the bridging technique.
