颈动脉粥样硬化对缺血性中风的发生起着重要作用。颈动脉粥样硬化与缺血性中风发生率之间关系的估价对缺血性中风发病机理的研究和缺血性中风预防都有重要意义。该研究应用超声显示颈动脉粥样硬化严重程度来预测将来发生缺血性中风的危险率。 使用7.5MHzB型多普勒超声检查214名日本病人颈动脉狭窄和溃疡斑块程度,以此评估颈动脉 Carotid atherosclerosis plays an important role in the pathogenesis of ischemic stroke. Evaluation of the relationship between carotid atherosclerosis and the incidence of ischemic stroke is of great importance for the study of the pathogenesis of ischemic stroke and prevention of ischemic stroke. The study used ultrasound to show the severity of carotid atherosclerosis to predict the risk of future ischemic stroke. 214 Japanese patients with carotid artery stenosis and ulcer plaque were examined using 7.5MHz B-mode Doppler ultrasound to evaluate the carotid artery
