目的探讨老年人颈动脉粥样斑块形成的特点。方法选择本院2006年9月至2009年2月收治的160例颈动脉粥样斑块形成患者行彩色多普勒超声检查。结果颈动脉斑块的总体发病率左侧高于右侧,斑块部位以颈动脉分叉处最多见,其次为颈总动脉主干及颈内动脉,颈外动脉发病率最低。结论彩色多普勒超声目前是诊断颈动脉粥样斑块形成的良好手段,它可以清楚观察到颈动脉粥样斑块的形态、性质、部位、管腔狭窄程度。
Objective To investigate the characteristics of carotid plaque formation in the elderly. Methods A total of 160 patients with carotid atherosclerotic plaque admitted from September 2006 to February 2009 in our hospital underwent color Doppler ultrasonography. Results The overall incidence of carotid plaque was higher on the left side than on the right side. The plaque site was the most common at the bifurcation of the carotid artery, followed by the common carotid artery and the internal carotid artery. The incidence of the external carotid artery was the lowest. Conclusions Color Doppler ultrasound is a good method to diagnose carotid atherosclerotic plaque. It can clearly observe the morphology, property, location and stenosis of carotid artery atherosclerotic plaque.
