目的：研究探讨乳癌术后皮瓣坏死的原因与防治．方法：总结我院490例乳癌根治术的手术经验．结果：1989年～1992年230例乳癌根治术皮瓣坏死率52％,1993年～1996年260例乳癌根治术皮瓣坏死率20％.两组有显著性差异（P＜0．01）．结论：乳腺癌术后皮瓣坏死的因素是多方面的，除手术因素外，我们认为术后管理也十分重要．
Objective: To study the causes and prevention of skin flap necrosis after breast cancer surgery. Methods: Summarize the surgical experience of 490 cases of radical mastectomy in our hospital. Results: From 1989 to 1992, the rate of flap necrosis was 230% in 230 cases of radical mastectomy. The rate of flap necrosis in 260 cases of breast carcinoma from 1993 to 1996 was 20%. There was a significant difference between the two groups (P<0.01). Conclusion: The factors of flap necrosis after breast cancer surgery are various. In addition to surgical factors, we believe postoperative management is also very important.
