  • Abstract
  • Look Inside

 An attempt to establish a correlation between the neurological findings and vertebral angiographic findings is made by studying 20 cases of circulatory disturbances of the vertebral artery suffering from vertigo and dizziness.

 1. Vertebral angiograms of all 20 cases showed circulatory disturbance. There were more than 50% stenosis in the extracranial vertebral artery in 5 cases; stenosis of the basilar artery, in 6 cases; and in the vertibrobasilar artery in another 8 cases.

 2. There are no clinical signs by which the location of the stenosis or occulusion of the vertebrobasilar artery may be identified. But when the main branch of the extracranial vertebral artery becomes stenosed the symptoms become more prominent particularly, in hearing loss, tinnitus and other cerebellar signs.
