目的：研究高血压患者颈动脉硬化斑块形成与高血压脑卒中的相关关系。方法采用高频彩色多普勒超声检测85例高血压并颈动脉硬化斑块形成患者及40名健康人颈动脉的内膜-中膜厚度及斑块形成情况，分析单纯高血压患者与高血压脑卒中患者颈动脉内膜增厚及斑块形成情况。结果85例高血压患者动脉硬化斑块形成共166处，其中硬斑块64处，软斑块102处；管腔狭窄共计30例，其中轻度管腔狭窄11例，中度狭窄12例，重度狭窄7例。以动脉粥样斑块3处以上作为预测患者发生高血压脑卒中，其敏感性80％，特异性82％，阳性预测值83％。结论高频超声能有效检测高血压脑卒中患者的颈动脉斑块形成，为临床预测高血压脑卒中提供有价值的信息。%Objective To study the correlation of the carotid arteries plaque in patients with hypertension com-plicating acute cerebral accident. Methods To detect the carotid arteries plaque in 85 patients with hypertension and carotid arteries plaque and 40 normal subjects by using color Doppler high-frequency ultrasound. Results There were 166 carotid arteries plaque in 85 cases, included 64 hard plaque and 102 soft plaque , 30 cases had carotid ar-teries stenosis, including 11 cases of slight stenosis, 12 cases of midrange stenosis and 7 cases of severe stenosis. Over 3 carotid arteries plaque could be used to predict acute cerebral accident with higher sensitivity as 80%, speci-ficity as 82%, and positive predictive value as 83%. Conclusion Color Doppler high-frequency ultrasound can be used to measure the carotid arteries plaque in patients with hypertension, which can offer valuable information for pre-dicting the hypertension complicating acute cerebral accident.
