【摘要】 目的:研究短暂性脑缺血发作(transient ischemic attack,TIA)与颈动脉粥样硬化相关性的超声学变化。方法:对临床确诊的120例TIA患者和110例非心血管疾病患者(对照组)进行颈动脉彩色多普勒超声检查,测量血管内径及内膜-中膜厚度(intima-medial thicknessI,TM),观察有无斑块形成和血管狭窄情况。结果:120例TIA患者中,颈动脉ITM增厚、斑块形成、管腔狭窄等血管异常者100例,发生率83.3%;对照组110例中有ITM增厚、斑块形成者42例,发生率38.1%,两组比较差异有统计学意义(P<0.05)。结论:短暂性脑缺血发作与颈动脉硬化密切相关,彩色多普勒超声能早期发现颈动脉硬化,可为TIA预测及评价提供重要指标。更多还原

【Abstract】 Objective: To study the pertinence of transient ischemic attack(TIA) and carotid atherosclerosis to color doppler ultrasonography.Methods: 120 patients confirmed by the TIA and 110 patients without cardiovascular disease were checked inside path of carotid artery and intima-medial thickness(ITM) to observe whether plaque formation and artery angiostenosis existed.Results: The abnormal signs of carotid arteries such as intima-media thickening,plaque formation and vascular constriction were found in 100 cases of 120 patients with transient ischemic attack(incidence rate was up to 83.3%).42 cases with intima-media thickening and plaque formation were checked out in the control group(incidence rate was up to 38.1%).There was statistical significance between the two groups(P<0.05).Conclusion: TIA are closely related to carotid artery atherosclerosis.Color Doppler uitrasound,through which carotid atherosclerosis can be early discovered,is an important indicator for prediction and assessment.更多还原
