Abstract

This paper discusses the value and surgical techniques of applying nano-silver combined skin flaps to repair large-area soft tissue defects in the calves and ankles. From January 2016 to December 2020, combined skin flap transplantation was used to treat 36 patients with large-area soft tissue defects in the calf and ankle, and nano-silver was used for wound wet compress. The study found 3 cases of vascular crisis in this group, and vascular exploration was carried out. After the arterial crisis was relieved, 1 case of free flap survived, 1 case of free flap edge necrosis, wound healing after dressing change, and 1 case of vein Partial necrosis of the free skin flap after embolization exploration. The remaining 33 patients with transplanted tissues all survived, and the wounds were repaired in one stage. The total success rate was 97.2% (35/36). The postoperative follow-up was 4 to 36 months, with an average of 16 months. The flap was soft and good in appearance, and the function of the affected limb and ankle was recovered satisfactorily. For this reason, we can conclude that the use of different forms of combined skin flap transplantation provides a feasible and effective technical method for the repair of large-area soft tissue defects in the calf and ankle. The nano-silver coating on the wound can effectively reduce the disability rate. Restore limb function.
