目的　评价直径为0.7 ～ 2 mm的血管用连续端端吻合法的价值。方法　对45只成年兔及30只成年鼠，随机分成外径为0.8 mm(,下同)、1.5 mm、1.9 mm的动脉组和外径为2.1 mm、1.1 mm的静脉组，共5组。每组动物一侧用端端连续吻合,另一侧用间断吻合。术后1、2、4周，各组选5只实验动物，行勒血试验、血管造影和组织学检查。结果　与血管间断吻合相比，血管连续吻合的时间能降低47 % ～ 22 %( P < 0.01）。血管吻合口的通畅率、血栓形成、以及血管内膜的修复，两者差异无显著性意义（P > 0.05）。结论　与间断吻合技术相比，连续端端吻合外径为0.7 mm ～ 2.2 mm的血管，能明显节省吻合时间。

Objective　To evaluate the merits of the continuous suture technique (CST)in end - to - end anastomosis of vessels with external diameter (ED) less than 2.0 mm. Methods　A total of 45 adult rabbits and 30 adult rats were used. The experiment was composed of five groups (n=15 for each)，group Ⅰ: rabbit carotid artery (1.8～2.0 mm ED), group Ⅱ: rabbit femoral artery (1.4～1.6 mm ED), group Ⅲ: rat femoral artery (0.7～0.9 mm ED), group Ⅳ: rabbit femoral vein (2.0～2.2 mm ED), and group Ⅴ: rat femoral vein (1.0～1.2 mm ED). In each animal, one side of the vessel was repaired using the CST, and the contralateral vessel with the interrupted suture technique (IST), Milk test, angiography and histological study of the anastomosed vessels were carried out to 5 animals from each group at 1, 2, and 4 weeks postoperatively. Results　There was no significant difference in patency rate, thrombus formation, and healing of vascular intima between the two suture techniques in vessels of any size. However, when compared to the IST, the CST could significantly (P＜0.01) reduce anastomosis time by 22 % to 47 %.Conclusions　The CST is a reliable and time - saving procedure in the end - to - end anastomosis of vessels with external diameter ranging from 0.7 mm to 2.2 mm.
