目的 :通过本组病例对乳癌术后皮瓣坏死原因的分析 ,总结防止皮瓣坏死之对策。方法 :回顾性病例分析。结果 :改进对皮瓣处理的操作后 ,皮瓣坏死率较改进前明显下降 ,改进后为 12 % ,改进前为 48%。结论 :横切口、创面严密止血、皮内连续缝合、持续负压引流、废弃加压包扎能显著降低皮瓣坏死的发生。另切忌皮下注射肾上腺素盐水过浅 Objective : To analyze the causes of skin flap necrosis after breast cancer in this group of cases and summarize the countermeasures to prevent flap necrosis. Methods: Retrospective case analysis. RESULTS: After the manipulation of the flaps was improved, the necrosis rate of the flaps was significantly lower than that before the improvement. The improvement was 12%, and the improvement was 48%. Conclusion : Transverse incision, tight wound closure, continuous intradermal suture, continuous negative pressure drainage, and waste pressure banding can significantly reduce the occurrence of flap necrosis.
