title: [The role of duplex scanning in diagnosing extravasal compression of vertebral arteries in degenerative diseases of the cervical part of the spine].
abstract: The method of duplex scanning was used in examination of 210 patients with degenerative-dystrophic diseases of the cervical part of the spine. It allows quantitative and qualitative assessment of the local and systemic hemodynamic value of extravasal compression of vertebral arteries. Local hemodynamic shifts in the area of extravasal influences on the artery were detected in 72.9% of the patients: decreased indices of blood flow and increased indices of peripheral resistance proximal to the compression zone, growing blood velocity in the area of the artery course deformity, in the place of its lumen constriction, decreased blood flow indices and indices of peripheral resistance distally to the compression zone. The assessment of blood flow in the vertebral arteries allows determination of the strategy of treatment of patients with degenerative-dystrophic diseases of the cervical part of the spine.
