摘要
为了探讨颈动脉内膜中层厚度与局限性颈动脉斑块的联系 ,对 91名受试对象的颈总动脉内膜中层厚度及颈内动脉和颈动脉分叉处的斑块进行超声检测 ,并将颈动脉内膜中层厚度进行分级。结果观察到有斑块者较无斑块者其颈动脉内膜中层厚度明显增加 ( 0 .83± 0 .16mm比 0 .6 4± 0 .12mm ,P <0 .0 1) ,且随斑块的严重程度增加 ,其内膜中层厚度呈增厚趋势。该结果支持颈总动脉内膜中层厚度与颈动脉局限性动脉粥样硬化斑块明显相关 。
Aim The paper was done to evaluate the relations between intima-media thickness (IMT) of common carotid artery (CCA) and plaque in the internal carotid artery (ICA) and bifurcations (CBs). Methods B-mode ultrasound examination of carotid arteries was per formed in 91 subjects. B-mode ultrasound examination include measurement of CCA-IMT and the sites of plaque in the ICA and CBs. Results The results showed that the prevalence of plaque increased from the lowest to the highest quintile of IMT(linear trend: P<0.01). The mean IMT was lower in subjects without plaques than in subjects with plaques (0.64±0.12 mm vs 0.83±0.16 mm,P<0.01), there was an increasing trend for IMT with the severity of plaque. Conclusion Increases in IMT as measured in the CCA are clearly related to atherosclerotic plaque in the ICA and CBs.
