Seventy femoral arterial avulsions with interpositional microvenous graft repairs were performed in rabbits and were divided into three groups. In Group A clamps were reapplied for 15 minutes with an overall patency rate of 97% after 3 weeks. The overall patency rate in Group B with 30 minutes reclamping was 93% three weeks later. Group C without clamping served as Controls and a 100% patency rate was achieved. The position of the microclamps, static blood in the region of the anastomoses and in the microvenous grafts as well as the time of reclamping up to 30 minutes did not influence the patency rate in damaged vessels after sufficient resection of injured vessel walls. The results of this experiment suggest that if necessary clamps can be reapplied safely in the clinical situation for up to 30 minutes after microvenous grafts have been completed to enable the microsurgeon to perform further dissection in a bloodless field.
在兔子身上进行了70例股动脉撕脱伤并采用静脉间置移植修复的手术,这些兔子被分为三组。A组再夹闭15分钟,3周后总体通畅率为97%。B组再夹闭30分钟,3周后总体通畅率为93%。C组不进行夹闭作为对照组,通畅率达到100%。微型夹的位置、吻合部位及静脉间置移植物中的静态血液,以及长达30分钟的再夹闭时间,在充分切除受损血管壁后,均不影响受损血管的通畅率。本实验结果表明,在临床情况下,必要时在完成静脉间置移植后可安全地再次夹闭长达30分钟,以使显微外科医生能够在无血视野中进行进一步的解剖。
