彩超对颈动脉粥样硬化与脑梗死的相关性研究

目的通过对颈动脉粥样硬化的超声检测,探讨颈动脉粥样硬化与脑梗死的关系。方法应用二维和多普勒超声技术分别检测38例脑梗死患者和32例非脑梗死患者颈动脉内/中膜厚度(intima-media thickness,IMT)、血管内径、斑块总积分、斑块总面积及血流速度,观察斑块的有无及形成情况。结果38例脑梗死患者中,颈动脉斑块发生率为80%,对照组中有斑块形成者检出率21%。两组相比较有显著性差异(P<0.01)。结论颈动脉粥样硬化与脑梗死的发病关系;高分辨率彩超诊断技术能早期发现颈动脉粥样硬化,对有效预防脑梗死的发生有重要的意义。

Correlation Study of Carotid Artery Atherosclerosis and Cerebral Infarction by Color Ultrasonography

Objective To evaluate the relationship between carotid artery atherosclerosis and cerebral infarction by ultrasonography. Methods All 38 patients with cerebral infarction and 32 patients without cerebral infarction were observed using two - dimension and Doppler ultrasonic technique. Intima - media thickness （IMT）, vascular diameters, blood stream velocities and plaque integral, plaque total area were recorded. Results Carotid arteries plaque detection rate was up to 80% among 38 cases of cerebral infarction and the control group was 21%. There was significant difference between the both groups（ P 〈 0. 01 ）. Conclusion Cerebral infarction and carotid artery atherosclerosis has relationship closely. Carotid artery atherosclerosis can be diagnosed in early period by high resolution color uhrasonography, which is important to prevent the occurrence of cerebral infaretion.
