摘　　要：目的探讨颈动脉彩色多普勒超声对预防中老年脑梗死的应用价值。方法应用高频彩色多普勒超声对南京军区杭州疗养院康复科80例中老年脑栓塞患者颈动脉进行检查,观察颈动脉(包块颈内、外和颈总动脉)内有无斑块,斑块性质以及血流动力学指标,并与同一时期另78例非脑梗死患者进行对比分析。结果脑梗死组颈动脉粥样斑块发生率(78.8%)明显高于非梗塞组(33.3%)(P<0.01);同时脑梗死组的收缩期峰值流速(PSV)、平均流速(V mean)较非梗塞组均明显降低(P<0.01),阻力指数(RI)和搏动指数(PI)均明显升高(P<0.01)。结论颈动脉粥样硬化斑块与中老年脑梗死密切相关,及时准确的检测结果可提高病变治愈率,对防止脑梗死的发生有非常重要的意义,并可延缓脑梗死的发生。颈动脉彩色多普勒超声对颈动脉粥样硬化斑块的检出率高,为了实现早期诊断、早期预防,建议使用彩超定期对中老年人颈动脉粥样硬化进行筛查。Objective To study the carotid artery color Doppler ultrasound application value for prevention of senile cerebral infarction. Methods High frequency color Doppler ultrasound was applied to the rehabilitation department check 80 cases of senile cerebral embolism in Hangzhou Sanatorium of Nanjing Military District in patients with carotid artery,carotid（bag piece of internal,external and common carotid artery） in presence of plaque,plaque nature and hemodynamic index were observed,with the same period,the other 78 cases of patients with cerebral infarction were analyzed. Results Carotid atherosclerosis plaque incidence of cerebral infarction group of 78.8% was obviously higher than that of non infarction group of 33.3%（P 〈0.01）; peak systolic velocity（PSV）,mean glow velocity（Vmean） and cerebral infarction group were significantly lower in the non infarction group（P 0.01）,resistance index（RI） and pulsation index（PI） were significantly higher（P 0.01）. Conclusion Carotid atherosclerotic plaques are closely associated with senile cerebral infarction,timely and accurate test results can improve the cure rate of the pathological changes,and it has very important significance for preventing the occurrence of cerebral infarction,and can delay the onset of cerebral infarction. Carotid artery color Doppler ultrasound flow imaging in carotid atherosclerosis plaque detection rate is high,in order to achieve early diagnosis and early prevention,it is recommended to use color Doppler ultrasound to exceed regular screening for carotid atherosclerosis among the elderly individuals.
