CORRELATION OF CLINICAL AND DOPPLER EXAMINATIONS DEPENDING ON THE CHARACTERISTICS OF CERVICAL SPINE TRAUMATIC DEFORMITIES

In patients with cervical spine injuries Doppler ultrasound is one of the most informative methods of diagnosis reveling structural functional disorders in the large vessels, vertebrobasiar basin. Hemodynamic disorders in the vertebral artery were analyzed with Doppler ultrasound in patients with traumatic deformation of the cervical spine with the aim of identifying its correlation with the nature of the initial damage, the amount of deformation and the terms of its existence. It was revealed that the most significant early criteria of hemodynamic disorders in the vertebrobasilar basin is changing of in the symmetry of maximum flow velocity and increase of resistance indexin the vertebrqal arteryat absence of the clinical signs of vertebrobasilar insufficiency. In 53.6 % of cases of Doppler ultrasound revealed hemodynamic instability in the form of the asymmetry of the maximum systolic flow velocity, clinical manifestations of vascular disorders in the vertebrobasilar basin were manifested only in 7.17% of patients with subtype DF3 and CF3, and the rest these disorders were compensated and subclinical. Negative influence of deformation of the terms of existence on increase of blood flow asymmetry in the vertebral arteries was revealed. The magnitude of angular deformity was not statistically significant for the manifestation of vascular disorders in patients with traumatic cervical spine deformation.
Key words: cervical spine, traumatic deformation, vertebral artery, Doppler ultrasound.
