Effect of the Layered Fasciocutaneous Flap in the Repair of Complex Wounds of the Lower Extremity

Abstract

Introduction. Repair of complex wounds of the lower extremity remains challenging for clinicians. When repairing complex wounds, it is necessary to customize the skin flap to simultaneously repair both the superficial soft tissue defect and the deep dead space wound. Objective. This case series describes the use of a layered fasciocutaneous flap with pedicled perforator to repair complex wounds of the lower extremity. Materials and Methods. Three cases with complex wounds of the lower extremity underwent repair using layered fasciocutaneous flap, and clinical efficacy was observed. Results. In cases 1 and 3, complete survival of the layered flaps was achieved. In case 2, congestion measuring 1 cm × 1 cm occurred at the distal end of the skin paddle, followed by superficial skin ulceration, which healed 2 weeks after a dressing change. Conclusion. These findings indicate that a layered fasciocutaneous flap with pedicled perforator can be used to repair complex wounds of the lower extremity.
