Clinical application of dorsal digital nerve fasciocutaneous flap with superficial vein anastomosis for repair of fingertip defects

Abstract

Objective To investigate the clinical efficacy of dorsal digital nerves fasciocutaneous flap with superficial vein anastomosis in the treatment of fingertip defects. Methods From January 2016 to February 2017, 25 cases (25 fingers) of fingertip defects were treated with proximal dorsal digital nerve fasciocutaneous flap. After the flap was transferred to cover the wound, the stump of a superficial vein retained at the proximal end of the flap was anastomosed to the stump of fingertip subcutaneous vein for reconstruction of flap venous circulation. Results All the flaps survived uneventfully. The appearance of flaps was good without blisters and purple skin 2 weeks after operation. The postoperative follow-up time ranged from 6 to 8 months with an average of 6.5 months. The flap had good appearance, no obvious bulky shape and soft texture. Some flaps had pigmentation. The skin pain and temperature sensation were restored. The joints of the fingers were in good motion. All the skin grafts survived. Conclusion The dorsal digital nerve fasciocutaneous flap with superficial vein anastomosis for repair of fingertip defects overcomes the shortcomings of the traditional flap with poor backflow, and the survival of the flap is effectively guaranteed.
