Abstract

The aim of our investigations was to characterize the relationship between basilar artery (BA) flow velocity in patients with cervical spondylosis and age, grade of radiological changes, prevalence of vertigo, and decreased blood flow velocity through vertebral arteries (VA) after head rotation. A prospective, controlled study in academic neurotology was conducted. We examined 80 patients with radiological evidence of cervical spondylosis. Forty patients complained of positional vertigo lasting more than 6 months. Patients were examined by transcranial Doppler ultrasound with head rotations. We showed significant association between velocity flow in basilar artery after neck rotation and age, prevalence of vertigo, grade of radiological changes, and positional vertebral artery flow lesion. Spondylotic-induced VA compression may be the reason for decreased blood flow velocity in the basilar artery during head rotation, which may be of particular importance for older patients, especia...
