OBJECTIVES: Major tissue loss caused by the critical limb ischemia requires improvement of distal perfusion and cover of large tissue defects. We propose a new method, the y-shaped subscapular artery flow-through (Y-SCAFT) muscle flap using the subscapular artery that yields an arterial graft and a free muscle flap sustained by a collateral branch of this artery. This prospective study evaluated the feasibility of this technique and analyzed wound healing, graft patency, and limb salvage.
METHODS: Between 2002 and 2007, 20 patients, mean age 64 years (range, 55-79 years), were treated with this technique. All presented with critical ischemia and major tissue loss, with exposure of the tendons, bones, or joint, and were candidates for major amputation. Revascularization and cover of tissue loss with the same Y-SCAFT anatomic unit was used for all patients. The distal anastomosis was performed between the distal branch of the Y-SCAFT and the pedal artery in 9, posterior tibial artery in 4, peroneal artery in 1, lateral tarsal artery in 3, and the plantar artery in 3. In four patients, the distal part of the arterial graft, including the anastomosis, was covered with the muscle flap because the tissue loss was nearby. The proximal anastomosis was performed between a leg artery and the arterial graft in 10 patients. A venous graft was necessary in 10 patients to extend the bypass proximally.
RESULTS: One patient died during the postoperative period. Duplex control evidenced patency all the Y-SCAFT muscle flaps. Healing was achieved in all patients. Mean follow-up was 31 months (range, 6-58 months). No patients died during follow-up. One patient presented occlusion of the Y-SCAFT muscle flap and underwent amputated. One patient had major amputation despite a patent graft. At 2 years, leg salvage was 85%, patency was 94%, and survival was 94%. At the end of the follow-up, 17 patients (1 death, 2 amputations) had a patent graft, a viable muscle flap, wound healing, and a functional leg.
CONCLUSION: We showed the clinical feasibility of the technique of Y-SCAFT muscle flap, which allows for revascularization and cover of major tissue loss with one anatomic unit. This method is particularly useful in selected cases with poor run-off and large ischemic lesions.
