Successful implantations of PTFE microvenous prostheses with 3M precise anastomosis systems were presented. Twelve PTFE prostheses (Gore-Tex;I.D.1.0 mm) were implanted into rat femoral veins by means of 3M precise technique to evaluated the patency rate. In the control group, PTFE prostheses (n = 12) were implanted by means of end-to-end technique. In the experimental group, patency of the PTFE prostheses was evaluated at 3 (n = 6) and 6 (n = 6) weeks after implantation by means of macroscopic inspection and scanning electron microscopy. All prostheses except one were patent at the time of removal (patency rate 91.7 percent). All the microvenous prostheses were completely covered by an endothelial layer at 3 and 6 weeks after implantation, and no stenosis was observed at the anastomotic sites. In the control group, all prostheses except one were found to be occluded 3 weeks after implantation. These results demonstrate the value of the 3M precise technique when implanting PTFE microvenous prostheses.
介绍了使用3M精确吻合系统成功植入聚四氟乙烯(PTFE)微血管假体的情况。采用3M精确技术将12个PTFE假体(戈尔特斯;内径1.0毫米)植入大鼠股静脉,以评估通畅率。在对照组中,通过端端技术植入PTFE假体(n = 12)。在实验组中,通过宏观检查和扫描电子显微镜在植入后3周(n = 6)和6周(n = 6)评估PTFE假体的通畅情况。除一个假体外,所有假体在取出时均通畅(通畅率91.7%)。所有微血管假体在植入后3周和6周均完全被内皮细胞层覆盖,吻合部位未观察到狭窄。在对照组中,除一个假体外,所有假体在植入后3周被发现闭塞。这些结果证明了3M精确技术在植入PTFE微血管假体时的价值。
