A quantitative analysis was undertaken to investigate the width and area of survival of flow-through venous flaps in 20 ears of 10 rabbits. The 3.0- x 3.0-cm flap models, which included one flow-through vein, were prepared with additional circulation from the graft bed and surrounding tissue excluded, as far as possible. The flaps were divided as follows: Group A--composite grafts (n = 10), and Group B--flow-through venous flaps (n = 10). All flaps in Group A became necrotic and all those in Group B showed partial survival along the flow-through vein. The average survival width was 1.10 +/- 0.48 cm, and the survival rate was 44 +/- 19.3 percent. Microangiograms revealed patency of the flow-through vein in all flaps of Group B. Histologically, there tended to be progressively more fibrous tissue in the area further away from the flow-through vein. The model is useful to investigate the width and area of survival in flow-through venous flaps.
对10只家兔的20只耳朵进行了定量分析，以研究通血静脉皮瓣的存活宽度和面积。制备了3.0×3.0厘米的皮瓣模型，其中包括一条通血静脉，并尽可能排除来自移植床和周围组织的额外血液循环。皮瓣分为以下两组：A组——复合移植物（n = 10），B组——通血静脉皮瓣（n = 10）。A组所有皮瓣均发生坏死，B组所有皮瓣均沿通血静脉呈现部分存活。平均存活宽度为1.10±0.48厘米，存活率为44±19.3%。微血管造影显示B组所有皮瓣的通血静脉通畅。组织学检查显示，在远离通血静脉的区域，纤维组织逐渐增多。该模型有助于研究通血静脉皮瓣的存活宽度和面积。
