Abstract

About 30% of all cases of cerebrovascular accident are associated with dyscirculation of the vertebrobasilar system, and among transient disorders, the share of the latter reaches 70%. 65% of cases of circulatory disorders in the brain stem formations are caused by damage to the extracranial parts of the vertebral arteries.
