BACKGROUND/AIM: Venous insufficiency after replantation or revascularization is one of the most common causes of limb loss in either the short or the long term. The aim of this study was to evaluate the results of a new technique to overcome venous insufficiency.
A crush-avulsion type of injury was formed in the femoral veins of rats of 3 separate groups. In the control group, primary repair was applied to the damaged veins and the remaining 2 groups were repaired with either an arterial graft or a vein graft. The success rates of anastomosis were then compared.
In the control group the patency rate was 25% in the 2nd hour, 12.5% on the 2nd day, and 12.5% on the 10th day. The patency rate in the vein group was 87.5% in the 2nd hour, 50% on the 2nd day, and 37.5% on the 10th day, whereas the patency rates in the artery group were 100% in the 2nd hour, 87.5% on the 2nd day, and 75% on the 10th day.
Microsurgery requires experience and patience. It can be considered that the use of arterial grafts for venous repair in replantation after crush-avulsion type amputations can increase the success rate of replantation.
背景/目的：静脉功能不全是再植或血运重建后肢体丧失的最常见原因之一，无论是短期还是长期。本研究旨在评估一种克服静脉功能不全的新技术的效果。
在 3 组大鼠中形成挤压-撕脱型股静脉损伤。在对照组中，对受损静脉进行一期修复，其余 2 组分别用动脉移植物或静脉移植物修复。然后比较吻合口的成功率。
在对照组中，第 2 小时吻合通畅率为 25%，第 2 天为 12.5%，第 10 天为 12.5%。静脉组第 2 小时吻合通畅率为 87.5%，第 2 天为 50%，第 10 天为 37.5%，而动脉组第 2 小时吻合通畅率为 100%，第 2 天为 87.5%，第 10 天为 75%。
显微外科需要经验和耐心。可以认为，在挤压-撕脱型断肢再植中，使用动脉移植物修复静脉，可以提高再植的成功率。
