椎基底动脉扩张延长症与后循环脑梗死

Vertebrobasilar dolichoectasia and posterior circulation cerebral infarction

椎基底动脉扩张延长症（VBD）作为一种独立的脑血管病变在临床并不少见，后循环脑梗死是VBD最常见的临床表现和最主要的死亡原因。关于VBD相关后循环脑梗死临床特点及病理生理机制目前仍处于探索和研究阶段，本文就近年相关研究进展予以综述。

Vertebrobasilar dolichoectasia （VBD） as a distinct arterial disease is not rare. Posterior circulation cerebral infarction was one of the most frequent events and the primary cause of death in patients with VBD. The clinicoradiologic features and the pathophysiological mechanism of ischemic stroke in VBD remained unclear and required further investigation. We aimed to provide a review of advanced studies.
