经颅多普勒超声联合颈动脉超声对颈动脉狭窄支架治疗的临床价值分析

Analysis of Clinical Value of Transcranial Doppler Ultrasonography and Carotid Ultrasound in the Treatment of Carotid Artery Stenosis

目的分析颈动脉超声和经颅多普勒超声联合对颈动脉狭窄支架的临床应用效果。方法选择该院2016年1—12月共计100例实行颈动脉狭窄支架的患者,使用经颅多普勒超声联合颈动脉超声的检测方式等检测患者的颈动脉狭窄局部管径,狭窄段收缩期峰值流速,搏动指数等相关指标,观察其测量效果。结果颈动脉狭窄患者实行颈动脉支架植入术后原来狭窄部位的局部管径从(3.24±0.75)mm逐渐增加为手术之后1周左右的(5.14±1.15)mm,治疗前后差异有统计学意义(t=5.152,P<0.05)。其他指标治疗前后亦差异有统计学意义(P<0.05)。结论对于颈动脉支架术后的患者来说,使用经颅多普勒超声检测联合颈动脉超声检测的方式能够表明患者血管内径和脑部血流动力学的改善情况优异,颈动脉超声和经颅多普勒超声联合可以作为颈动脉支架植入术疗效评价的重要手段。

Objective To analyze the clinical effect of carotid artery ultrasound and transcranial Doppler ultrasound on carotid artery stenosis. Methods A total of 100 cases of carotid artery stenosis stent in our hospital from January to December 2016 year, and the local diameter of carotid artery stenosis, peak systolic peak velocity in narrow section and pulsatility index of patients was tested by the carotid artery ultrasound and transcranial Doppler ultrasound, and the measurement effect was observed. Results After the carotid artery stent implantation, the local diameter of carotid artery stenosis increased from（3.24±0.75）mm to（5.14±1.15）mm in 1 week after operation, and the difference before and after treatment was significant（t=5.152,P〈 0.05）. There were significant differences in other indexes before and after treatment（P〈 0.05） Conclusion For patients after carotid artery stenting, the transcranial Doppler detection combined with carotid artery ultrasonography can show the improvement of brain hemodynamics in patients with vascular diameter is excellent, and the carotid artery ultrasound and transcranial Doppler ultrasound can used as a major means in evaluating the curative effect of carotid artery stenting.
