Résumé
Objective To summarize the clinical effect and experience of vacuum sealing drainage ( VSD) technology combined with sural neurovascular flap to repair chronic and infection soft tissue defects in the foot and ankle?Methods From 2010 to 2015, the clinical effect of 58 cases patients who were treated negative pressure drainage combined with sural nerve nutrient vessel flap for repairing foot and ankle chronically infected wounds in Zhongnan Hospital of Wuhan University were retrospective analyzed?All cases were treated by debridement,negative pressure suction 1, 2 times, cleaning the wound, Wound secretions were negative after culture,then cut and take the nutrient vessels of the nutrient vessels to repair the wound?Results All flaps survived completely in 58 cases,54 cases inⅠstage healing,postoperative 4 cases were suffered with distal skin flap necrosis,and healed after dressing?The outline and function were satisfactory during 1 to 3 years follow?up?Conclusion The effect of negative pressure drainage combined with sural nerve nutrient vessel flap for repairing chronic wound of foot and ankle is exact, skin flap transposition of the wound should be thoroughly debridement,edge scar tissue should be appropriate resection.
