目的为了解脑梗塞患者颈动脉粥样硬化的发生率及其与高血压等主要危险因素的关系。方法对115例36～81岁患者的颈总动脉、颈总动脉分叉部及颈内动脉起始段做了颈动脉B型超声检查，观察指标为颈动脉内-中膜厚度（IMT）、斑块发生情况、直径狭窄百分率。结果发现脑梗塞患者颈动脉斑块的发生率为69．6％，随年龄增加，斑块的发生率逐渐增高，但粥样硬化病变致管腔严重狭窄（＞70％）的发生率很低。结论颈动脉粥样硬化病变与脑梗塞有很好的相关性。
Objective To understand the incidence of carotid atherosclerosis in patients with cerebral infarction and its relationship with the major risk factors such as hypertension. Methods B-mode carotid artery ultrasound was performed in 115 cases of 36- to 81-year-old patients with carotid artery, bifurcation of common carotid artery and the beginning of internal carotid artery. The indexes of carotid artery intima-media thickness (IMT) Plaque incidence, the percentage of diameter stenosis. The results showed that the incidence of carotid plaque in patients with cerebral infarction was 69.6%. The incidence of plaque was gradually increased with age, but the incidence of severe stenosis (> 70%) in atherosclerotic lesions was very low . Conclusion There is a good correlation between carotid atherosclerosis and cerebral infarction.
