Evaluation of hemodynamics in vertebral arteries in case of herniated cervical intervertebral discs using functional tests

Background. Degenerative changes of the vertebral-motor segment occupy an important place among causes cervicogenic headache, neck pain with radiation to shoulder and arm, noise in head, dizziness. The same symptoms are often found vertebral artery syndrome, which is a set disorders vertebral-basilar dynamics. Dopplerography makes it possible obtain quantitative parameters blood flow arteries, thereby assessing level pathological flow.
 Purpose. Dopplerographic assessment arteries patients herniated cervical intervertebral discs using functional tests.
 Materials methods. An analysis results dopplerography 42 young was carried out. Peak systolic velocity (Vs), end-diastolic (Vd), indices peripheral resistance (RI) pulsatility (PI), minute volume (HOK – Vvol) second VA at C2-C3 were determined prob.
 Results discussion. With left-sided hernia, value Vs left during contralateral head rotation 34.1 ± 2.9 cm/s, RI 0.71 0.03, PI 1.04 0.06, HOC 85 9 ml/min, comparison group 45.3 3.8 0.59 0.02, 0.85 0.04, 118±13 respectively. In right-sided right 32.6 3.2 0.72 1.03 COC 83 8 44.8 4.1 0.60 0.87 117 12 difference between Doppler obtained disc herniation (persons without herniation) significant (P < 0.05).
 Conclusion.Hemodynamically disruption occurs when paramedian posterolateral hernia localized on side name opposite side. These violations consist decrease speed flow, increase compared persons herniation.
