摘　　要：椎-基底动脉狭窄和闭塞常常引起后循环缺血性病变,并可增加卒中再发的几率。数字减影血管造影(digital subtraction angiography,DSA)是诊断椎-基底动脉狭窄和闭塞的金标准,但其为有创性检查。近年来,随着与超声相关的新技术的快速发展,使其能够早期、准确的诊断椎-基底动脉狭窄或闭塞。本文旨在对椎-基底动脉狭窄和闭塞的超声影像学进展进行综述,以增加医生对超声影像检查在椎-基底动脉狭窄和闭塞方面的认识。Vertebro-basilar stenosis and occlusion can cause ischemia of the posterior circulation, and increase risk of stroke recurrence. Intra-arterial angiography is the gold standard of identify vertebro-basilar stenosis and occlusion. Recently, the new techniques associated with ultrasound have been developed rapidly. It is possible to use ultrasound to identify vertebro-basilar stenosis and occlusion in the early stage. This article summarize the progress of ultrasound imaging techniques for detecting vertebro-basilar stenosis and occlusion, to increase the understanding of ultrasound imaging for detecting the vertebro-basilar stenosis and occlusion.
