Abstract：Objective To compare the effects of four kinds of small vessel anastomosis methods in animal experiment. Methods 80 Wister rats were randomly divided into four groups,20 cases in each group.The end of the interrupted suture method,equidistant symmetrical lobulation,small vascular mattress suture and three-pin suture method and other anastomosis were used respectively.The time of anastomosis and the patency rate of blood vessel were observed.The histomorphological chan-ges of the anastomotic region were observed by light microscope at different time.Results The immediate patency rates of the four groups after operation all were 100%.The long-term patency rate was 94.05%in the interrupted suture group,97.5%in the equidistantly lobulated group,95%in the mattress suture group and 100%in the three-pin suture group.There was no sta-tistical difference (P>0.05).The average anastomosis time:anastomosis time of three-pin suture group was shorter than the other three methods of anastomosis,and there was a statistical difference(P<0.05).The morphological changes of the vascular tissue after the operation:in three-pin suture group,vascular intima injury was light,the wall of each layer was clear,and the inflammatory reaction was mild.Conclusion Three-pin suture method is a good choice for small vessel anastomosis,with short operation time,light vascular intima injury,mild inflammation and fast recovery.
