目的研究彩色多普勒超声检查 颈动脉IMT及斑块与缺血性脑卒中的相关 性，为今后临床实践提供参考和借鉴。 方法 选取2013年5月-2014年9月期间我 院收治的98例缺血性脑卒中患者为研究 对象，另外再选择84例非心脑血管疾病 的患者为对照组进行研究，探讨颈动脉 IMT及斑块与缺血性脑卒中的相关性，研 究彩色多普勒超声检查的诊断价值。结 果 卒中组患者IMT增厚、斑块形成的发 生率明显高于对照组患者，p＜0.05；卒 中组高血压、高血糖、高血脂以及吸烟 情况明显高于对照组患者，p＜0.05，差 异具有统计学意义。结论 颈动脉斑块以 及狭窄主要发生于高龄人群中，与缺血 性脑卒中的发生具有十分密切的关系； 彩色多普勒超声检查具有无创的优势， 能够清楚的显示颈动脉中的斑块位置以 及范围，对于防控高龄人群脑卒中的发 生具有重大的意义。

Objective This paper is to investigate the correlation between color Doppler ultrasongraphy applied on carotid artery IMT, plaques and ischemic cerebral apoplexy, and to offer the references for clinical practices in the future. Methods Ninety eight patients with ischemic cerebral apoplexy admitted by the Hospital during the period from May, 2013 toSeptember, 2014were selected as research object, and 84 patients without cardiovascnlar and cerebrovascular diseases were selected into the control group to study, the correlation between carotid artery IMT and plaques and ischemic stroke was explored, and the diagnosis value of color Doppler ultrasongraphy was investigated. Results The incidence rate for IMT thickening and plaque formation of patients in the stroke group was significantly higher than that of patients in the control group (p < 0.05). The hypertension, hyperglycemia, hyperlipidemia, and smoking conditions of patients in the stroke group were significantly higher than that of patients in the control group (p <0.05), and the differences were statistically significant. Conclusions The carotid artery plaque and the stenosis mainly occur in aged populations, and they are closely correlated to the occurrence of ischemic cerebral apoplexy. The color Doppler ultrasongraphy poses noninvasive advantage, and it can clearly shows the position and extent of the plaque in the carotid artery, delivering great significance on the prevention and control over the occurrence of cerebral apoplexy among aged populations.
