The distal part of the subdermal vascular network (SVN) random skin flap on the rabbit was radiated with He-Ne laser at an energy density of 3.15 J/cm2. The blood vessels of the flap were perfused with Chinese ink. Histological examinations and image analysis were applied to evaluate the effects of He-Ne laser radiation on the SVN skin flap. It was found that the revascularization and the survival 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, especially the veins, and anastomosis of the vessels between the flap and the recipient site.
以能量密度3.15 J/cm2的氦氖激光照射兔皮下血管网（SVN）随意皮瓣的远端部分。用中国墨汁灌注皮瓣血管。应用组织学检查和图像分析来评估氦氖激光照射对SVN皮瓣的影响。结果发现，在早期，SVN随意皮瓣的血管再生和成活率与皮瓣长宽比例密切相关。氦氖激光照射可改善皮瓣的微循环并提高其成活率，这主要是由于血管扩张，尤其是静脉扩张，以及皮瓣与受区之间血管的吻合所致。
