彩超对颈动脉粥样硬化与缺血性脑血管疾病的研究

目的 :研究颈动脉粥样硬化与缺血性脑血管疾病的关系。方法 :彩超检查 1 4 0例缺血性脑血管疾病患者的颈动脉 ,测量血管的直径、内 -中膜的厚度 (intima- media thickness,IMT) ,血流的速度等参数 ,观察斑块的有无及形成情况 ,并检查 1 0 0例健康志愿者作为对照组。结果 :1 4 0例缺血性脑血管疾病患者中 ,颈动脉有粥样硬化、血管重构、IMT增厚、斑块形成、管腔狭窄等血管异常者占 1 2 0例 ,检出率达 85.7% ;对照组中有 IMT增厚和软斑形成 1 7例 ,检出率为 1 7.0 % ,二者比较有显著差异 (P<0 .0 1 )。结论 :缺血性脑血管疾病和颈动脉粥样硬化存在着线性关系 ;高分辨率彩超诊断技术 ,对颈动脉粥样硬化检出预报和疗效的观察、评价有重要意义

Color Ultrasonographic Research on the Relationship Between Common Carotid Artery Atherosclerosis and Ischemic Cerebrovascular Disease

Objective:To analyze and discuss the relationship between common carotid artery atherosclerosis and ischemic cerebrovascular disease.Methods:All carotid arteries of 140 patients with ischemic cerebrovascular diseases were examined with color ultrasonography and vascular diameters,intima media thickness(IMT),plaques and blood stream velocities were measured and compared with 100 controls.Results:The abnormal signs of carotid arteries such as atherosclerosis,vessel reconstruction,intima media thickening,plaque formation and vascular constriction were found in 120 cases of 140 patients with ischemic cerebrovascular disease and total lesion detection rate was up to 85 7%.Seventeen cases with intima media thickening and soft plaque formation were checked out in the control group and the lesion detection rate was up to 17%.There was significant difference between the two groups( P <0 01).Conclusions:The linear relation is obviously existed between ischemic cerebrovascular disease and common carotid artery atherosclerosis.It is significantly important that the diagnostic technique using high frequency body surface color ultrasonography can inspect common carotid artery atherosclerosis and predict the occurrance of ischemic cerebral disease and evaluate the therapeutic effect for the disease.
