【摘要】　目的　評價青年人頸動脈彩色多普勒超聲檢查的臨床意義，并探討青年人腦梗死與頸動脈粥樣硬化的關系。　方法　 2008年2月-2011年3月，對256例青年腦梗死患者進行頸動脈彩色多普勒超聲檢測，選擇性別和年齡匹配的健康青年143例作對照組，比較兩組人群頸動脈彩色多普勒超聲特點的差異。　結果　腦梗死組頸動脈粥樣硬化斑以中等、強回聲斑塊為主，斑塊積分、血管壁內-中膜厚度（ITM值）及斑塊檢出率（34.77%，89例）均明顯高于對照組（P lt;0.01）；腦梗死組頸動脈硬化狹窄率及血栓發生率明顯高于對照組（P lt;0.05， lt;0.01）。　結論　青年腦梗死患者頸動脈粥樣硬化及血栓形成發生率均高，提示青年腦梗死患者的發病主要原因與動脈粥樣硬化有關。IMT值的增加、斑塊的檢出率及形態學特征等是頸動脈病變與腦梗死發生的有意義的檢測指標，在青年人腦梗死的防治中是有參考意義較大的超聲學指標。
【Abstract】　Objective　 To assess the clinical significance of color Doppler ultrasonography in examining carotid arteries of young patients, and explore the relationship between cerebral infarction and carotid arteriosclerosis in young patients. 　Methods　 A total of 256 patients with cerebral infarction and 143 people without cerebral infarction diagnosed between February 2008 and March 2011 were assessed by color doppler ultrasonography. The ultrasonic characteristics of the two groups were compared and analyzed.　Results　 Plaques incidence in cerebral infarction group was 81.43% which was higher than that in the control group. The most common sites of plaque formation were common carotid artery (CCA) bifurcate and the initial segment of internal carotid artery (ICA) in young people with cerebral infarction. In the cerebral infarction group, the rate of middle-echoic plaques was higher than that in the control group (P lt;0.05). The rate of low-grade carotid stenosis was higher in the cerebral infarction group than that in the control group (P lt;0.05).　Conclusions　 Cerebral infarction occurrence in young people is closely correlated to carotid artery atherosclerosis. Ultrasonography can provide objective evidences for preventing and treating cerebral infarction.
