筋膜皮瓣再血管化动态变化的实验研究

目的：为探讨筋膜皮瓣移植术后，其愈合过程中血管形态的动态变化及其临床意义。方法：在猪的两后肢外侧，分别设计筋膜皮瓣或普通皮瓣。应用微血管灌注、组织切片、计算机图像分析等方法，于术后定时地观察皮瓣愈合过程中血管形态的动态变化。结果：①在再血管化过程中，筋膜皮瓣血管增生的速度及幅度，均优于普通皮瓣；②筋膜皮瓣近、中、远各部再血管化明显同步，普通皮瓣远端则未见明显再血管化。结论：筋膜皮瓣血供与其深筋膜血供变化同步

Experimental study of dynamic vascular changes during fasciocutaneous flap revascularization

Objective: Dynamic vascular changes during fasciocutaneous flap revascularization and its clinical significance were studied postoperatively.Methods: Fasciocutaneous flap or ordinary flap was desigened at the lateral side of either hindlimb of the pig.Dynamic vascular changes were investigated by microangiography,microscopy and computerized image analysis system at regular intervals after operation.Results:The blood vessels of fasciocutaneous flap grew faster than those of ordinary flap during revascularization.Marked revascularization could be noticed at proximal,mid or distal portion of fasciocutaneous flap,but no visible revascularization could be viewed at distal portion of ordinary flap. Conclusions:Vascular changes of fasciocutaneous flap were synchronous with that of its deep fascia.
