摘要
目的 采用超声检查评价脑梗死患者颈动脉粥样硬化斑块稳定性及分布状况.方法 对100例脑梗死患者和20例健康体检者行颈动脉彩色多普勒超声检查,根据超声检查结果将检出颈动脉粥样硬化斑块的患者分为稳定斑块组和易损斑块组.观察脑梗死患者颈动脉粥样硬化斑块的发生率,分析脑梗死与不同颈动脉斑块的关系.结果 100例脑梗死患者中有78例检出颈动脉粥样硬化斑块,其中41例检出易损斑块.20例老年健康体检者中有9例检出颈动脉粥样硬化斑块,其中3例为多发斑,6例为双侧斑.超声检查对脑梗死患者颈动脉粥样硬化斑块的检出率明显高于对照组(P＜0.01).结论 彩色多普勒超声检查能无创评价脑梗死患者颈动脉粥样硬化斑块的稳定性,从而有助于判断脑梗死患者缺血发生机制和评价危险因素,在高危人群筛查、指导药物和手术治疗方面有着广阔的应用前景.
Objective To evaluate state of carotid atherosclerotic plaques stability and distribution in patients with cerebral infarction by color Doppler ultrasonography.Methods Carotid artery color Doppler ultrasonography was performed in 100 patients and 20 normal control subjects.The patients with carotid atherosclerotic plaques were divided into either stable -plaques and unstable -plaques groups according to the results of ultrasonography.The incidence of carotid atherosclerotic plaques was observed in patients with cerebral infarction.The relashionship between cerebral infarction and carotid atherosclerotic plaques with stable or unstable was analyzed.Results Seventy - eight cases in the 100 patients with cerebral infarction were detected carotid atherosclerotic plaques(78%), of this patients, 41 cases were unstable- plaques.Nine cases in the 20 normal control subjects were detected carotid atherosclerotic plaques.The detectable rate of carotid atherosclerotic plaques in cerebral infarction was significantly higher than that in control group(P ＜ 0.01).Conclusions Color Doppler ultrasonography assess the stability of carotid atherosclerotic plaques in patients with cerebral infarction.thus it is helpful to estimate the mechanism of ischemia and evaluate its risk factors.So it has a wide application prospect in screening high -risk Population, guiding drug administration and Surgical intervention.
