title: The extended deep inferior epigastric pedicle flap for lower extremity reconstruction.
abstract: Large soft-tissue defects of the lower extremity can present a challenging reconstructive problem. The extended deep inferior epigastric pedicle flap is a versatile and reliable flap that can be used for the coverage of complex lower extremity soft-tissue defects as far distal as the knee. We reviewed our 5-year experience with 20 consecutive extended deep inferior epigastric pedicle flaps used to cover lower extremity defects. All wounds, including 4 soft-tissue defects of the knee, were successfully covered. Two minor complications occurred. Flap anatomy, surgical approach, and new refinements in flap design are presented. The indications for the flap and its role in ablative tumor surgery are discussed. This flap has proved to be versatile, easy to raise, and extremely hardy. The ample skin island with its large arc of rotation is well vascularized, healing well even in irradiated wounds, and the flap tolerates both postoperative pressure and radiation.
