title: [Cerebral circulation using transcranial and extracranial doppler ultrasonography in a patient with vertigo and ischemia in the area of the brain stem].
abstract: The authors examined 32 patients with vertigo, 17 patients with focal ischaemia of the brain stem and 24 patients without signs of affections of the central nervous system by transcranial and extracranial Doppler ultrasonography. They measured the flow velocity in the basilar artery (BA), in the intracranial portion of the vertebral artery (VA) and in the extracranial portion of the internal carotid artery (ICA). In patients with vertigo they investigated functional and organic changes in the area of the cervical spine. They found significant differences in the flow velocities between groups as well as in different indices calculated from the assessed values. The lowest flow velocities were recorded in patients with focal ischaemia of the brain stem. The authors evaluate the influence of haemodynamics and disease of the cervical spine on the development of vertigo.
