摘　　要：目的:观察激光血管吻合和缝线血管吻合术吻合血管后耐压强度的变化,探讨不同吻合方法对血管功能恢复的影响及其原因。材料和方法:家兔30只,右侧颈动脉采用缝合法,左侧颈动脉用激光法加以血管支撑物吻合血管。术后1d、3d、7d、14d、28d,分别观察血管通畅率和耐压强度变化。结果:激光吻合方法通畅率高于缝线吻合方法。激光吻合与缝线吻合的血管耐压强度无差异,趋势是激光法在术后前几天比缝线法低,从7d后耐压强度高于缝合组。结论:利用激光吻合血管有利于保持血管的长期畅通,但初始耐压强度低。应当研究激光吻合加强剂及合适的激光工作方式等提高激光组织吻合的初始耐压强度等力学参数。Objective: To study the difference of bursting pressure after laser and artificial suture vascular anastomosis. Methods: The left and right carotids were respectively anaslomosised with laser welding and artificial suturing methods for 30 rabbits. The changes of vascular palance rate and the bursting pressure were observed afler 1 d,3 d.7 d.14 d and 28 d. Results: Compared with the artificial suturing: anastomosis method, the palance rate of the laser welding one is higher for all groups,but the bursting pressure is complicated, It seems that,for the laser welding method,the strength of bursting pressure is lower in 7 days and become higher only after 7 days. Conclusion: The laser welding method is preferable to the artificial suturing one for the blood flow. In order to improve the primary bursting pressure it is necessary to find the more suitable binding agent and effective laser welding way.
