目的：探讨彩超对颈动脉斑块形态及狭窄程度与脑卒中的相关性。方法回顾性分析227例临床确诊为脑卒中患者（脑卒中组）的彩超表现，以同期经体检、心电图和常规超声检查正常的健康者为对照组（230例），比较2组彩超检查结果、分析颈动脉斑块形态及狭窄程度。结果脑卒中组双侧颈动脉不规则型斑块发生率高于对照组（84．1％比10．9％，P＜0．05）；脑卒中组双侧颈动脉狭窄程度≥50％发生率高于对照组（71．8％比3．0％，P＜0．05）。结论彩超能显示颈动脉内斑块位置、类型及狭窄程度，可为脑卒中疾病的诊断、治疗等提供依据。

Objective To investigate the relationships of carotid plaque morphology and steno-sis degree to stroke with color Doppler ultrasound.Methods Color Doppler ultrasound findings of 227 patients with clinically confirmed stroke (stroke group)were retrospectively analyzed.In addition,230 healthy subjects who underwent physical examination,electrocardiographic monito-ring and conventional ultrasound scan during the corresponding period were selected as the con-trol group.Carotid plaque morphology and stenosis degree were compared between the two groups.Results The percentages of patients with irregular plaques and patients with stenosis≥50% in stroke group were significantly higher than those in control group (84.1% vs 10.9% and 71.8% vs 3.0%,respectively;P<0.05).Conclusion Color Doppler ultrasound can display the location and type of carotid artery plaques and the degree of stenosis.Therefore,it can provide a basis for the diagnosis and treatment of stroke.
