【摘要】 目的 :运用高频超声探讨颈动脉作为反映冠状动脉粥样硬化体表窗口的可行性。方法 :用高频超声测量正常人和 1、 2、 3支冠脉狭窄组的颈动脉 IMT、斑块面积、Crouse积分和血流频谱测值。结果 :冠脉病变组 IMT值显著高于正常组 ,但冠脉病变组之间无差异。冠脉病变组的斑块发生率、斑块面积和 Crouse积分均显著高于正常组 ,且 2、3支病变组斑块面积和 Crouse积分明显高于 1支病变组。四组患者的血流频谱测值均无显著性差异。结论 :颈动脉可作为一个良好的体表窗口 ,在一定程度上反映冠状动脉粥样硬化的有无和病变程度更多还原

【Abstract】 Objective:To discuss the feasibility of taking carotid artery as a clue for detecting coronary artery atherosclerotic lesions.Methods:The IMT,plaque area,Crouse score and Vmax,Vmin,RI and PI of carotid artery were measured by HFU in normals and coronary artery diseased(CAD)1,2,3vessel groups.Results:The IMT is significant thickened in coronary atherosclerotic lesions,has no significant variance of the 1,2,3vessel groupsThe plaque areas and Crouse score are higher,more severe in 2 and 3vessel groupsThe Vmax,Vmin,PI and RI have no difference for the above 4 groups.Conclusion:Carotid artery is an idea superficial window to discover the coronary atherosclerotic lesions.更多还原
