[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.

[The effect of neck rotation on auditory evoked brainstem potentials in patients with degenerative cervical spine changes].

Using the neck rotation test during recording of auditory brainstem evoked potentials the authors examined 60 subjects aged 16-60 years, including 20 healthy ones and 40 with cervical spondylarthrosis. The Neuromatic 2000 C Dantec device was used. Half the patients with cervical spine changes had also receptive hearing damage of low degree. The study demonstrated that neck rotation affected the latency time of the analysed waves I and II. The time was significantly prolonged in the patients with spondylarthrosis. The authors believe that simultaneous prolongation of the mean latency between waves I-III suggests worse compensation of circulation in patients, especially in the initial part of the auditory pathway. The authors think that the neck rotation test could be used in the study of brainstem auditory evoked potentials as a challenge test.
