彩色多普勒超声在动脉血管吻合术疗效评估中的应用

目的探讨彩色多普勒超声在评估动脉血管吻合术疗效中的应用价值。方法应用彩色多普勒超声仪对16条桡动脉2、条尺动脉吻合术后疗效进行观察,以动脉吻合术后2周、24周血管吻合口处血管内径和峰值血流速度、血流量作为疗效评估指标,同时以健侧桡、尺动脉相同部位的超声检测值作正常对照。结果术后2周,15条桡动脉吻合口处收缩期峰值血流速度升高,与正常对照组相比两组差异有显著性意义(P<0.05),血流量和血管内径缩小,但与正常对照组无显著性差异,余3条动脉吻合口处血流频谱呈单峰,收缩期峰值血流速度明显增高,吻合口远端血流频谱低平;术后24周吻合口处收缩期峰值血流速度较正常对照组增高,血流量降低,但均无显著性差异。结论彩色多普勒超声可作为评价动脉血管吻合术疗效的一种无创、简便及较为可靠的检查方法。

The role of color doppler ultrasonography in evaluating the arterial anastomosis

Objective To study the effects of arterial anastomosis by color doppler ultrasonography.Methods Anastomosis of affected sixteen radial arteries,two ulnar arteries and their counterparts were studied by color doppler ultrasonography for their diameters and hemodynamics.Results Two weeks after operation,the peak systolic velocity of the affected fifteen radial arteries increased by comparing with the normal(P<0.05).The blood flow volume and the diameters were decreased,however,there were no significant difference between the anastomosed vessels and the control side.The other anastomosed vessels showed decreased diameters.After 24 weeks,the peak systolic velocity increased,the blood flow volume decreased,however,there were no significant difference between the anastomosed vessels and the control side.Conclusion Color doppler ultrasonography can provide confident method for evaluating the therapeutic effect of artery anastomosis.
