摘　　要：目的探讨彩色多普勒超声检测在颈动脉狭窄患者治疗效果评估中的应用价值。方法选取2017年6月至2020年5月本院收治的80例颈动脉狭窄患者作为研究对象。比较治疗前后颈动脉狭窄程度,并采用彩色多普勒超声检测患者治疗前后颈动脉斑块厚度变化及周边血流动力学指标,采用二元Logistic回归分析彩色多普勒超声指标对颈动脉狭窄程度的影响因素。结果治疗后,患者颈动脉狭窄程度明显低于治疗前,差异有统计学意义(P<0.05)。治疗后,轻度颈动脉狭窄患者斑块厚度低于中度颈动脉狭窄患者,差异有统计学意义(P<0.05)。治疗后,轻度颈动脉狭窄患者舒张末期血流速度(EDV)、收缩期最大流速(PSV)及血管阻力指数(RI)均低于中度颈动脉狭窄患者,差异有统计学意义(P<0.05)。二元Logistic回归分析显示,患者斑块厚度、EDV、PSV、RI均为颈动脉狭窄程度的影响因素(OR>1,P<0.05)。结论颈动脉狭窄患者经常规治疗后颈动脉狭窄程度明显改善,采用彩色多普勒超声检测斑块厚度情况及周边血流动力学指标可反映颈动脉狭窄程度,进而为临床治疗效果评估提供重要的参考依据。Objective To explore the application value of color Doppler ultrasound in the evaluation of therapeutic effect of patients with carotid artery stenosis.Methods 80 patients with carotid artery stenosis who were admitted to our hospital from June 2017 to May 2020 were selected as the research subjects.carotid artery stenosis degree before and after treatment in patients were compared,the changes of carotid plaque thickness and peripheral hemodynamic indexes before and after treatment were detected by color Doppler ultrasound.binary Logistic regression was used to analyze the influencing factors of color Doppler ultrasound indexes on the degree of carotid artery stenosis.Results After treatment,the degree of carotid artery stenosis in patients was significantly lower than before treatment,and the difference was statistically significant(P<0.05).After treatment,the plaque thickness of patients with mild carotid stenosis was lower than that of patients with moderate carotid stenosis,and the difference was statistically significant(P<0.05).After treatment,the end diastolic velocity(EDV),peak systolic velocity(PSV)and resistance index(RI)of patients with mild carotid artery stenosis were lower than those of patients with moderate carotid artery stenosis,and the difference was statistically significant(P<0.05).Binary logistic regression analysis showed that plaque thickness and EDV,PSV,RI of carotid artery were all influencing factors of carotid artery stenosis(OR>1,P<0.05).Conclusions The degree of carotid artery stenosis in patients with carotid artery stenosis is obviously improved after routine treatment.Using color Doppler ultrasound to detect plaque thickness and peripheral hemodynamic indexes can reflect the degree of carotid artery stenosis,and then provide an important reference for clinical treatment effect evaluation.
