摘　　要：血管性眩晕是一种常见的眩晕。椎动脉优势是一种血管观象，其发生机制尚不清楚，可引起椎底动脉改变和后循环血流动力学改变。椎动脉优势可通过多种机制促发血管性眩晕。Vascular vertigo is a common vertigo. Vertebral artery dominance is a vascular phenomenon, and its mechanism remains unclear. It causes basilar artery changes and hemodynamic changes in posterior circulation. Vertebral artery dominance may trigger vascular vertigo through a variety of mechanisms.
