The role of sartorius muscle flaps in the management of complex groin wounds.

A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was whether sartorius muscle flaps (SMF) can be effectively used in the setting of complex groin wounds with exposed prosthetic grafts for graft salvage and limb salvage. The literature review identified 33 articles reporting on the use of SMF for complex vascular wounds. Of these, 7 articles reporting on the use of 539 SMFs were considered the best evidence to answer the clinical question. Indications included surgical site infections with or without wound dehiscence, lymph leaks, graft infection and groin pseudoaneurysms, whereas in 98 of the included 539 cases, the flaps were performed prophylactically. Vacuum-assisted closure systems were used in 25 cases to promote healing. The use of an SMF is associated with low rates of muscle flap and graft complications, whereas outcomes seem to be independent of the presence of occlusive disease in the superficial femoral artery. They can be effectively combined with aggressive debridement strategies and vacuum-assisted closure devices to optimize outcomes. The published literature supports the use of SMF in the management of complex groin wounds following vascular reconstruction and is associated with encouraging flap, limb and graft salvage rates.
