Resurfacing of the donor defect after wrap-around toe transfer using the Y-V vascular pedicle lengthening technique / 中华显微外科杂志

ABSTRACT

Objective To explore the methods of Y-V vascular pedicle lengthening technique for cover-age of the defect of great toe after wrap-around flap transfer, and decrease the morbidity of donor site in great toes. Methods Fifteen patients received three kinds of flap for immediate resurfacing of donor defect of the great toes during wrap-around flap transfer, all flaps were harvested with Y-V vascular pedicle lengthening technique. Among them, 9 cases received the free lateral tarsal flaps transplantation for coverage of defect in donor great toes, 5 cases was repaired by medial tarsal flaps, and only one was treated by the medial plantar flap. Results All the flaps survived postoperatively. The medial plantar flap encountered the venous crisis in postoperative 3 days, and regained the normal blood supply after continuous bleeding for 2 days. All patients were satisfied with cosmetic and functional outcome in average 10- month follow-up. The appearance and sensory function of donor toe repaired by medial tarsal flaps was best among three ones. Conclusion Depending on the Y-V vascular pedicle lengthening technique, the local pedical flaps of foots are enlarged scope for coverage of great toe after wrap-around flap harvest, which can decrease the complication of donor site at the most.
