Objective To explore the feasibility and clinical effect of autologous fat concentrate combined with split-thickness skin grafts in the repair of venous ulcer. Methods From January 2015 to December 2018, a total of 16 patients diagnosed with venous ulcer were admitted to our department, and all patients received symptomatic and supportive treatment such as local debridement and dressing change. After the granulation tissue grew well, all patients received autologous adipose concentrate combined with spilit-thickness skin graft for repair. Results All the grafted skin survived well, and the survival rate of grafted skin at 2 weeks after surgery was 86% to 99%. All patients were followed up to 6 months after surgery. The wounds of all patients were healed during the follow-up period. One patient suffered local ulcer recurrence due to repeated friction after healing and the ulcer recovered after dressing changing treatment. All the other patients had no recurrence during the follow-up period. The scar hyperplasia in the skin transplantation area was not obvious and the healing quality was good. No significant surgical complications occurred. Conclusions Autologous lipoconcentrate combined with split-thickness skin grafts is an effective and safe method in the repair of venous ulcer, and the application of autologous lipoconcentrate can effectively improve the survival rate and healing quality of skin grafts.
