傍轴型血管型与随意型的SVN薄皮瓣成活对比研究

A COMPARATIVE STUDY ON SURVIVAL OF SVN THIN FLAP BY AXLAL VESSEL WITH THAT OF RANDOM PATTERN SVNTF

目的：探讨不同类型真皮下血管网薄皮瓣成活的差别。方法：以5只小型猪为实验动物，分别于胸腰背部形成随意型、于骼腹部形成倍轴型血管型的真皮下血管网薄皮瓣，所有皮瓣长、宽、蒂宽、形状、手术操作均相同。术后第7天观察。结果：两种皮瓣坏死面积不同（P＜0．05）。结论：傍轴型血管型真皮下血管网薄皮瓣成活情况明显优于随意型者。

To investigate the survival difference between two types of subdermal vascular network SVN thin flap. Methods:Five pigs were utilized. A random flap was raised on thoracolumbodorsal region, another one of the same sizewith its pedicle closed to deep iliac circumflex vessel was on iliogastric area. Results: The necrosis areas were observed 7 days postoperatively and had a sig nificant difference between two flaps(P<0. 05). Conclusion: The SVN thin flap by axial vessel survived much better than that of random pattern.
