摘　　要：目的 :探讨颈动脉粥样硬化与脑梗死的关系。方法 :对 132例经CT、MRI证实的脑梗死患者和 10 4例非脑梗死患者行颈动脉彩超检查 ,测量血管的内径、内膜—中层厚度 (IMT) ,血流的速度等参数 ,观察斑块的有无及其形成情况。结果 :132例脑梗死患者中 ,颈动脉有IMT增厚、斑块形成、管腔狭窄等血管异常者占 114例 ,检出率为 86 .3% ,对照组中有IMT增厚和斑块形成 19例 ,检出率为 18.2 % ,二者比较有显著性差异 (P <0 .0 1)。结论 :脑梗死和颈动脉粥样硬化有密切的相关性 ;高分辨率彩超诊断技术能早期发现颈动脉粥样硬化 ,对预防脑梗死的发生有重要的意义。Objective:To evaluate the relationship between carotid artery atheroslierosis and cerebral infarction.Methods:All 132 patients with cerebral infarction and 104 patients without cerebral infarction diagnosed by CT and MRI were examined in vascular diameters, intima-media thickness (IMT), blood stream velocities and plaques with color ultrasosography.Results:The abnormal signs of carotid arteries such as intima-media thickening,plaque formation and vascular constriction were found in 114 cases of 132 patients with cerebral infarction and total lesion detection rate was up to 86.3%;19 cases with intima-media thickening and plaque formation were cheeked out in the control group and the lesion detection rate was up to 18.2%.There was significant difference between the two groups (P<0.01).Conclusion:Cerebral infarction and carotid artery atherosclerosis are closely related.Carotid artery atherosclerosis can be diagnosed in early period by high frequency body surface color ultrasonography, which is important to prevent the onset of cerebral infarction.
