[The effect of degenerative cervical spine lesions and blood flow velocity in vertebrobasilar system in Doppler measurement].

The purpose of the study was to establish the effect of degenerative lesions of cervical vertebrae on blood flow velocity in the vertebrobasilar system measured by means of Doppler phenomenon using Transpect--TCD device according to generally accepted principles. The study was carried out in 20 healthy controls and 40 individuals with these lesions (aged 16-60 years). It was found that blood flow velocity in this arterial system is highly variable individually. In patients with degenerative changes pathological reduction of this velocity was found in this system which is an unquestionable evidence of the influence of these lesions on blood flow in vertebral arteries.
