Objective. To study peculiarities of vertebral and cerebral hemodynamic disorders in adolescents with cervical spine osteochondrosis. Material and Methods. The examination of 220 adolescents at the age of 14 to 18 years was conducted, which included clinical, radiographic, neuropsychologic, ultrasonic and neurophysiologic techniques. Results. Asymmetry of linear blood velocity in vertebral artery (VA) was observed in 95.0 % of cases with compression irritative type of vertebrogenic VA syndrome and in 77.2 % – with reflex angiospastic type. Bilateral reduction of linear blood velocity in VA was revealed in 5.0% of cases with compression irritative type and in 22.8 % – with reflex angiospastic type of VA syndrome. Conclusion. Hemodynamic changes in VA in adolescents with cervical osteochondrosis manifest themselves through asymmetry and bilateral reduction of linear blood velocity in VA.
