摘　　要：颈内动脉闭塞可由多种病因导致,患者临床表现差异较大,可无症状或发生严重的卒中事件,其临床表现异质性和复发卒中风险取决于多种因素,包括闭塞特征、血流动力学变化和侧支循环。在颈内动脉闭塞患者的诊疗过程中,多种影像学技术贯穿始终并起到至关重要的作用,作者就颈内动脉闭塞及侧支循环的多种影像学评估方法进行综述。Internal carotid artery occlusion(ICAO)can be caused by a variety of causes,which presents diverse clinical manifestations in patients ranging from asymptomatic to acute severe stroke syndromes.This extreme variability and the risks of recurrent stroke depend on the various vascular risk factors,including the characteristics of occlusion,hemodynamic alterations,and collateral circulation.A variety of imaging techniques is throughout the process of diagnosis and treatment in patients with ICAO,which plays a vital role.This article aims to review various imaging methods for the evaluation of internal carotid artery occlusion and collateral circulation.
