彩超对颈动脉粥样硬化与慢性脑供血不足相关性的研究

Study the pertinence of carotid atherosclerosis and CCCI with color Doppler ultrasonography

目的:研究颈动脉粥样硬化与慢性脑供血不足(chronic cerebral circulation insufficiency,CCCI)的关系。方法:应用彩色多普勒超声对86例确诊为CCCI患者的颈动脉进行血管内径测量,内膜-中膜厚度(intima-medial thickness,IMT)测量,观察有无斑块形成和血管狭窄情况。结果:86例CCCI患者中,有颈动脉硬化(IMT增厚和斑块形成)78例,检出率达90.7%,其中IMT增厚达29.1%,斑块形成达61.6%。结论:CCCI与颈动粥样硬化存在着线性关系,早期检测颈动脉粥样硬化可预CCCI的发病,提高早期诊治率,减少缺血性脑血管病的发生。

Objective：To study the relation of carotid atherosclerosis and chronic cerebral circulation insufficiency （CCCI）. Methods： Apply color Doppler ultrasonography to check 86 patients confirmed by the CCCI, measure inside path of carotid artery and intima-medial thickness（IMT）, observed plaque formation and artery stenosis.Results：In 86 CCCI, 78 cases was carotid atherosclerosis （the IMT increases with plaque formation） the checkout rate amounts to 90.7%, among them the IMT increase was 29.1%, the plaque formation was 61.6% .Conclusion：There was a linear relationsldp between the CCCI and the carotid atherosclerosis,earlier examination of carotid atherosclerosis can prevent the CCCI, increase the earlier diagnosis and cure rate, reduce the occurrence of ischemia cerebrovascluar disease.
