真皮下血管网皮瓣蒂部的作用

Experimental study on the role of the pedicle of the subdermal vascular network skin flap

目的考察真皮下血管网皮瓣的蒂部作用。方法用健康、白色家猪的实验,按自身相互对照原则在动物躯干两侧分别设计真皮下血管网皮瓣、传统皮瓣动物模型。通过两组皮瓣成活过程的大体观察,及皮瓣 ECT 检查核素分布情况的比较方法进行研究。结果真皮下血管网皮瓣成活长度、面积均值较传统皮瓣有显著差异(P<0.05)。ECT 检测示实验组与对照组核素分布均相似局限于近蒂端,长宽比为(1～1.5)∶1。结论真皮下血管网皮瓣蒂的作用与传统皮瓣相似,对其超长成活部分作了可能的解释。

Objective The experiment was to investigate the role of the pedicle of the subdermal vascular network skin flap.Methods Ten healthy white pigs,weighting from 20 to 25kg were used. The subdermal vascular network skin flap and the traditional skin flap were designed and created on each side of the animal's flank.The traditional skin flap on the contralateral side of the flank was used as control.Flap survival was studied by gross observation and ECT examination of isotope distribution. Results There were significant differences between the two groups in mean survival length and area (P <0.05).In both groups the radioactive isotope gathering is restricted proximally with a ratio of length to width of (1—1.5):1.Conclusion The presence of the pedicle of the subdermal vascular network skin flap makes no difference compared the traditional skin flap.
