Of the various techniques known, simple interrupted sutures remain the gold standard in the microanastomosis of vessels. Tying many knots, however, is time consuming. This may be of more significance with tissue such as the jejunum, which is significantly effected by ischemia time, or when several vessels are to be anastomosed. In this study, 60 femoral arteries of rabbits were divided into three equal groups. The arteries were then divided and repaired using simple interrupted, simple continuous, and continuous locked sutures. Application of the Bonferroni t-test revealed that both groups of arteries repaired using continuous sutures exhibited a statistically significant (p < 0.02) reduction in anastomosis time (50%) compared with interrupted suture techniques. However, there also was a 45% incidence of reduction in flow (9 of 21 anastomoses) when the simple running suture technique was utilized, giving the running locked suture unquestionable superiority.
在已知的各种技术中，单纯间断缝合仍然是血管显微吻合的金标准。然而，打许多结很耗时。对于像空肠这样受缺血时间影响显著的组织，或者当要吻合多条血管时，这可能更具重要性。在本研究中，将60只兔的股动脉分成三组，每组数量相等。然后分别用单纯间断缝合、单纯连续缝合和连续锁边缝合法对动脉进行离断和修复。应用Bonferroni t检验显示，与间断缝合技术相比，采用连续缝合法修复的两组动脉吻合时间均有统计学意义的显著缩短（50%，p < 0.02）。然而，当采用单纯连续缝合法时，血流量减少的发生率为45%（21例吻合中有9例），这使得连续锁边缝合法具有无可争议的优势。
