颈动脉彩色多普勒超声在老年缺血性脑卒中诊断中的应用价值

Application Value of Carotid Artery Color Doppler Ultrasound in the Diagnosis of Ischemic Stroke in the Elderly

目的:分析颈动脉彩色多普勒超声在老年人缺血性脑卒中诊断中的应用价值。方法:选取2019年1月至2020年12月期间福建医科大学附属第一医院收治住院的首发老年缺血性脑卒中患者32例(观察组)及同期门诊健康老年体检者32例(对照组)作为研究对象,两组研究对象均实施颈部血管彩色多普勒超声检查,比较两组颈部血管管腔狭窄、斑块、颈总动脉内–中膜厚度(IMT)值及颈动脉血流参数等。结果:观察组患者的颈动脉斑块检出率、管腔狭窄率、易损斑块检出率高于对照组,差异均具有统计学意义(P<0.05)。观察组患者的IMT、血流阻力指数(RI)均高于对照组,颈总动脉的峰值流速(PSV)、舒张末期流速(EDV)及管腔内径低于对照组,差异均具有统计学意义(P<0.05)。结论:颈动脉彩色多普勒超声不仅能全面观察颈动脉斑块形成及管腔狭窄情况,也能准确判断斑块的性质及血流动力学改变,对预测老年人缺血性脑卒中的发生有积极意义。

Objective To analyze the application value of carotid artery color doppler ultrasound in the diagnosis of elderly ischemic stroke.Methods A total of 32 first-onset ischemic stroke in senile patients admitted to the First Affiliated Hospital of Fujian Medical University from January 2019 to December 2020(observation group)and 32 healthy elderly people who underwent physical examination during the same period(control group)were selected as the research objects.Color doppler ultrasound examination of cervical vessels was performed in both groups.Cervical vascular lumen stenosis,plaque,common carotid intimamedia thickness(IMT)and carotid blood flow parameters were compared between the two groups of study subjects.Results The detection rate of carotid plaque,lumen stenosis and vulnerable plaque in observation group were higher than those in the control group,with statistical significances(P<0.05).The IMT and blood flow resistance index(RI)in observation group were higher than those in the control group,and the peak systolic velocity(PSV),end diastolic flow velocity(EDV)and lumen diameter of common carotid artery in the observation group were lower than those in the control group,with statistical significances(P<0.05).Conclusion Carotid artery color doppler ultrasound can not only comprehensively observe the carotid artery plaque formation and lumen stenosis,but also accurately determine the nature of the plaque and hemodynamic changes,which has positive significance for predicting the occurrence of ischemic stroke in the elderly.
