目的 探讨如何降低乳腺癌根治术后皮瓣坏死的发生率。方法 对45例采用预防皮瓣坏死新方法的乳腺癌根治术病例与过去实施的1210例乳腺癌根治术病例进行了分组对比研究。结果 乳腺癌根治术后的皮瓣坏死率由原来的45%下降到目前的2%，经统计学处理，二者有极显著差异。结论 预防乳腺癌根治术后皮瓣坏死的关键是：防止腋下淋巴管瘘，腋下肋下置双管引流，合适的胸带包扎力，合理的皮瓣厚度及皮瓣缝合不能有张力。

Prevention of skin flapnecrosis following eradicative operation of breast cancer

Objective To study how to reduce the incidence rate of skin flap necrosis after the eradicative resection of breast cancer.Methods 45 patients with breast cancer underwent eradicative operation with new methods to prevent the necrosis of skin flap,and they were studied and compared with 1210 cases treated by traditional ways.Results With the new methods adopted,the necrosis rate of skin flap following eradicative operation of breast cancer was reduced from 45%(original)to 2%(present).Statistic analysis showed that there was outstanding difference between them.Conclusion In the eradicative operation of breast cancer,the key to prevent the necrosis rate of skin flap is:prevention of subaxillary lymphatic fistula,two tubular drainage set individually in subcostalis and subaxillaris,appropriate force of chest bandaging,proper thickness of skin flap and perfect suture without tension.n subcostalis and subaxillaris,appropriate force of chest bandaging,proper thickness of skin flap and perfect suture without tension.
