摘要:

[目的]介绍弱碱性溶液泡洗后股后穿支皮瓣修复膝下截肢端慢性创面的手术技术及其临床疗效。[方法]2021 年 1 月—2024 年 1 月，针对膝下截肢患者小腿残端慢性感染创面，清创后应用本科自制弱碱性溶液 （pH 值 7.5~8.0） 浸泡残端创面，3 次/d，浸泡 1 周，感染控制、创面清洁后，二期行股后穿支皮瓣移植修复残端慢性创面。[结果]本组 7 例创面均顺利愈合，皮瓣成活良好，无皮瓣坏死、皮瓣下积液及感染复发等并发症。[结论]弱碱性溶液泡洗后股后穿支皮瓣移植修复在膝下截肢端慢性创面治疗中疗效显著。

Abstract:

[Objective] To introduce the surgical technique and primary clinical outcomes of the below knee amputation chronic wound repair by femoral posterior perforator flap after soaking with weak alkaline solution. [Methods] From January 2021 to January 2024, 7 patients received abovesaid treatment for chronic infected wound of below knee amputation. After debridement, the wound was soaked in a weakly alkaline solution (pH 7.5~8.0) made by our department three times a day for one week. As the infection controlled with a clear wound, the amputated stump was repaired with posterior femoral perforator flap transplantation in the second phase. [Results] All the 7 cases had the wound healed successfully with the skin flap survived well, without complications such as skin flap necrosis, fluid accumulation under the skin flap and infection recurrence. [Conclusion] The repair of femoral posterior perforator flap after intermittent soaking with weak alkaline solution is effective method in the treatment of chronic wound of below knee amputation.
