椎动脉发育不全及其临床意义

Vertebral artery hypoplasia and its clinical significance

椎动脉发育不全是一种先天性血管变异，其发生率为1．9%～26．5%。近几年的研究显示，椎动脉发育不全可能是后循环脑梗死的潜在危险因素，特别是当与其他脑血管危险因素并存时。椎动脉发育不全可能导致局部的血流低灌注和复杂的神经血管调节，而与偏头痛也存在一定的联系。

Vertebral artery hypoplasia is a congenital vessel variation. Its incidence is from 1. 9 to 26. 5% . In recent years, studies have shown that vertebral artery hypoplasia may be a potential risk factor for posterior circulation infarction, especialy when it coexists with other cerebrovascular risk factors. Vertebral artery hypoplasia may also cause regional hypoperfusion and complex neurovascular regulation, and it also has a certaln link with migralne.
