摘　　要：为了探明激光对真皮下血管皮瓣血管重建有无影响,使用能量密度为3.15J/cm^2的 He-Ne激光照射兔随意型真皮下血管网皮瓣远1/3段。皮瓣血管内灌注墨汁,用组织切片、图像分析等方法对此型皮瓣的成活及血管重建状况进行观察。结果表明,随意型真皮下血管网皮瓣早期血供范围受皮瓣长宽比例的限制。He-Ne 激光照射可改善皮瓣的微循环,提高皮瓣成活率,主要原因是扩张了血管,尤其以静脉为著;并能促进与创缘和基底部血管的吻合生长。The distal part of the subdermal vascular network (SVN) random skin flap on the rab- bit was radiated with He-Ne laser at an energy density of 3.15J/cm^2.The blood vessels of the flap were perfused with Chinese ink.Histological examinations and image analysis were applied to evaluate the ef- fects of He-Ne laser radiation on the SVN skin flap.It was found that the revascularization and the sur- vival rate of the SVN random skin flap were highly related with the proportion of the length to width of the flap in the early stage.The radiation of the He-Ne laser could improve the microcirculation of the flap and increase its survival rate,which was mainly resulted from dilation of the blood vessels,especial- ly the veins,and anastomosis of the vessels between the flap and the recipient site.
