老年人颈动脉粥样硬化与脑梗死关系的临床分析

目的探讨老年人颈动脉粥样硬化与缺血性脑血管病的关系。方法彩超检测136例缺血性脑血管病患者的颈动脉,测量颈总动脉后壁IMT（内膜-中层）厚度,观察斑块的有无及形成情况;并检查非缺血性脑血管病患者102例作为对照组。结果136例缺血性脑血管病患者中,颈动脉有粥样硬化、斑块形成等血管异常者123例,异常检出率为90.44%;对照组中为35例,异常检出率为34.31%,两者比较差异有显著性（P〈0.01）。颈动脉粥样硬化斑块最常见于颈动脉分叉处,其次为颈内动脉起始段,但左右侧间差异无显著性（P〉0.05）。结论缺血性脑梗死患者的颈动脉粥样硬化程度明显重于非脑血管病患者,颈动脉粥样硬化的不稳定性斑块脱落是造成脑梗死的重要发病原因之一。

The elderly with carotid atherosclerosis and clinical analysis of the relationship between cerebral infarction

Objective To study the elderly carotid atherosclerosis and ischemic cerebrovascular disease. Methods 136 cases of color Doppler ultrasound detection of isehemic cerebrovascular disease in patients with carotid artery, carotid artery wall measuring IMT （intima - media thickness Ⅰ）, observation of plaque formation and whether or not; and check the non-ischemic cerebrovascular disease 102 cases of patients as a control group. Results 136 cases of isehemic cerebrovascular disease patients have carotid atherosclerosis, plaque formation of 123 cases of abnormal blood vessels, abnormal detection rate of 90.44%, the control group for 35 cases, abnormal detection rate of 34.31% The difference was significant （P 〈0.01）. Carotid atherosclerotic plaque in the carotid artery the most common forks, followed by internal carotid artery segment, between left and fight side but there was no significant difference （P〉 0.05）. Conclusions Patients with isehemic stroke of carotid atherosclerosis significantly more important than non-patients with cerebrovascular disease,carotid atherosclerosis plaque instability are caused by falling incidence of cerebral infarction in one of the reasons why essential.
