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：高频彩超检查30例脑梗死患者的颈动脉,测量其内径、内-中膜厚度（IMT）,血流速度等参数,观察斑块的有无及形成情况,并以28例健康自愿者作为对照组。结果：30例脑梗死患者中,颈动脉粥样硬化斑块形成,管腔狭窄等血管异常者26例,检出率占87%;对照组中有IMT增厚和斑块形成5例,占18%,二者比较有显著差异（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。

STUDY OF CORRELATION BETWEEN CAROTID ARETRY ATHEROSCLEROSIS AND CEREBRAL INFARCTION BY COLOR UITRASONOGRAPH

Objective：To evaluate the relationship between carotid artery atherosclerosis and cerebral infarction by ultrasonography.Methods：All 30 patients with cerebral infarction and 28 patients without cerebral infarction were observed using two-dimension and Doppler ultrasonic technique1 Intima-media thickness（IMT）,vascular diameter,bloodstream velocities and plaque integral,plaque total area were recorded.Results：Carotid arteries plaque detection rate was up to 87% among 30cases of cerebral infarction and the control group was 18 % 1 . There was significant difference between the both groups （ P 〈 0.01 ）. Conclusion：Cerebral infarction and carotid artery, atherosclerosis had close relationship between them. Carotid artery atherosclerosis can be diagnosed in early period by high resolution color uhrasonography, which is important to prevent the occurrence of cerebral infarction.
