The web artery perforator pedicled propeller flap for covering donor site defect of reverse digital artery island flap

Abstract

Objective To introduce the surgical techniques and clinical efficacy of repairing donor site defect of reverse digital artery island flap by the web artery perforator pedicled propeller flap. Methods Twelve cases with skin defects of the fingertips were treated with reverse digital artery island flaps transfer. Defects at the donor site were repaired with the web artery perforator pedicled propeller flap. The size of the digital artery island flaps ranged from 1.5 cm×2.0 cm to 2.0 cm×3.5 cm. The web artery perforator pedicled propeller flaps measured from 1.5 cm×2.0 cm to 2.0 cm×3.5 cm. Results All 24 flaps survived with primary wound healing. The patients were follow-up for 1 to 18 months. The appearance and texture of the perforator flaps were good. The width and depth of the web space were not affected. The abduction angle of the injured finger was close to normal. There were no complications such as scar contracture, tenderness, and nerve conduction abnormalities. Conclusion The web artery perforator pedicled propeller flap for covering donor site defect of reverse digital artery island flap is a safe and effective surgical technique. Its advantages include constant blood supply, simple operation, and fewer complications. Key words: Surgical flaps; Microsurgery; Web artery; Perforator pedicled propeller flap
