摘要： 摘要： 目的 应用超声测量评价颈总动脉(Common carotid artery)内-中膜厚度(Intima-Media Thickness，IMT)，颈总动脉内径(Diameter，D)与颈动脉粥样硬化(Carotid artery Atherosclerosis, CAS )间的关系, 探讨IMT与D作为CAS指标的敏感性,为脑梗死的早期防治提供依据。方法 应用彩色多普勒超声诊断仪,对40例高血压中、高危患者以及40例高血压低危患者行颈动脉超声检查,记录每例受检者双侧颈总动脉IMT和D。结果 ①高血压中、高危组IMT，D明显高于低危组（P <0.05 ）；②高血压中、高危组IMT或D单独异常率与低危组相比具有显著差异性（P <0.05 ），而IMT、D联合异常率则具有极显著差异性（P <0.01）。结论 颈总动脉IMT的增加，D的增大可作为反映CAS客观指标，并且两者同时异常对CAS的评价更具敏感性。

Abstract: ABSTRACT：　Objective　To evaluate the relationship between common carotid artery (CCA) intima-media thickness (IMT),common carotid artery diameter(D) and carotid artery atherosclerosis(CAS) by ultrasonograph . Investigated IMT and D as a sensitivity indicator of the CAS,and to provide an early prevention for cerebral infarction. . Methods　 The carotid artery of 40 high-risk group and the 40 mild dangerous group with hypertension were assessed by color Doppler ultrasonography. IMT and D were measured at the common carotid arteries .Results ①The IMT, D of hypertension the high-risk group are higher than the mild dangerous group obviously（P <0.05 ）；②There was a significant difference in abnormal rate of isolated IMT or D between hypertension high-risk group and mild dangerous group（P <0.05 ），but there was a extremely significant difference with the abnormality both IMT and D to compare（P <0.01） . Conclusion The enlargement of common carotid artery IMT and D as a objective maker to CAS, but coexistent abnormalities of IMT and D are more sensitive to CAS.
