摘　　要：目的探讨带浅静脉干的逆行皮瓣早期微血管构筑变化的特点以供临床实践参考。方法应用生物体视学技术测量带浅静脉干皮瓣微血管体积密度,结合组织学观察,与不带静脉干皮瓣作对照比较。结果带浅静脉干皮瓣组微血管密度整体水平高于不带静脉干皮瓣组(P<0.05)。结论浅静脉干的存在有利于皮瓣的血管化进程,保留浅静脉干对皮瓣成活有利。Objective To study the effects of the superficial venous trunk （SVT）and its nourishing vessels on early revascularization of the reverse-flow random flap in order to provide theoretical evidences for clinical applications. Methods The morphologic changes of micrangium of the reverse-flow random flap with SVT and without SVT were observed at different phases and compared by optical microscopy and stereological methods. Results The micrangium density of the flaps with SVT and without SVT showed a tendency of increasing at 3 days after the operation. At 5 to 10 days, the micrangium density of the flap with SVT was much higher than the flap without SVT. There was significant difference between the two groups, which was proved by the optical microscopy observation. Conclusions This study suggests that SVT and its nourishing vessels could promote early revaseularization of the flap after transplantation. The SVT can be of benefit to the survival of the reverse-flow random flap.
