本研究确定了袖带技术在大鼠模型中用于小口径血管移植的可行性。在12只大鼠的腹主动脉中，采用袖套技术或缝合技术将移植物植入1cm段。袖带技术的平均主动脉夹闭时间为29分钟，缝合技术为44分钟;袖带技术明显更短。植入后1周的腹部血管造影显示9只大鼠无明显狭窄，每种技术各1只大鼠移植物中部局灶性狭窄，缝合技术1只大鼠移植物完全闭塞。我们在动物模型中成功地将袖套技术用于小口径血管移植物的吻合。
This study determined the feasibility of the cuff technique for small-caliber vascular grafts in a rat model. A graft was implanted with the cuff technique or suture technique in a 1-cm segment of the abdominal aorta in 12 rats. The mean aortic clamp time was 29 minutes with the cuff technique and 44 minutes with the suture technique; the cuff technique was significantly shorter. Abdominal angiography at 1 week after implantation showed no significant stenosis in 9 rats, focal stenosis of the mid-portion of the graft in 1 rat with each technique, and total occlusion of the graft in 1 rat with the suture technique. We have successfully used the cuff technique for anastomosis for small-caliber vascular grafts in an animal model.
