Extracorporeal bypass preserved composite anterior thigh free flap (periosteo-musculo-fascio-cutaneous) for hemipelvectomy reconstruction: utilizing the periosteal component for abdominal wall fascial reconstruction.

Abstract

We present a case of a right external hemipelvectomy for chondroblastic osteosarcoma originating from the right ilium and reconstruction with salvage parts; cardiopulmonary bypass preserved anterior thigh free flap. The resection required sacrifice of the right common iliac artery and vein and the entire right gluteus maximus muscle. The first stage of the procedure was a high above-knee amputation on the ipsilateral leg. The amputated extremity was placed on extracorporeal bypass utilizing the common femoral artery and vein. This technique, previously unreported, supported the successful utilization of the anterior thigh free flap for both soft tissue and abdominal wall facial reconstruction.
