目的 :为了解急性脑梗死患者颈动脉粥样硬化的发病情况及与急性脑梗死高危因素的关系。方法 :对 92例急性脑梗死患者采用美国HPSONOS 45 0 0彩色多普勒超声诊断仪 ,行颈动脉超声检测 ,并对其有无动脉粥样斑块及狭窄进行评估并进行统计分析。结果 :急性脑梗死患者颈动脉粥样斑块的发生率为 63 .0 4% ,颈动脉狭窄的发生率为2 1.74% ,高危因素中高脂血症与颈动脉粥样硬化显著性相关 ,高血压、糖尿病及吸烟史与颈动脉粥样硬化未达到显著性相关。结论 :急性脑梗死患者颈动脉狭窄的发生率较低 ,但普遍有颈动脉粥样斑块的形成 ,是急性脑梗死发病的重要因素之一。
Objective: To investigate the incidence of carotid atherosclerosis in patients with acute cerebral infarction and its relationship with the risk factors of acute cerebral infarction. Methods: A total of 92 patients with acute cerebral infarction were examined by HPSONOS 45 000 color Doppler sonography. Carotid artery ultrasonography was performed to assess the presence or absence of atherosclerotic plaque and stenosis and statistical analysis. Results: The incidence of carotid atherosclerotic plaques was 63.04% in acute cerebral infarction patients, and the incidence of carotid artery stenosis was 2 1.74%. High risk factors of hyperlipidemia were significantly associated with carotid atherosclerosis and high Blood pressure, diabetes and smoking history did not reach significant correlation with carotid atherosclerosis. Conclusion: The incidence of carotid artery stenosis in patients with acute cerebral infarction is low, but the formation of carotid artery plaque is common, which is one of the important factors in the pathogenesis of acute cerebral infarction.
