title: [The effect of the instability of cervical spine on the hemodynamics in the vertebrobasilar system].
abstract: 256 patients with cephalgia were examined. The main cephalgia cause was a cervical instability. We showed importance of extended examinations for cephalgia pathogenesis. We estimated cerebral circulation by ultrasound (cerebral blood flow registration) methods. We found an intact blood flow in both vascular systems (arterial and venous) in 19.9% cases. Cervical instability more 3 mm vertebra dislocation was not always a cause of vertebral discirculation. Quite often a vertebra dislocation under 3 mm was a result of vertebra-basilar disordes.
