title: [Influence of positional blood flow disorders in the vertebral and basilar arteries on the prevalence of vertigo in patients with cervical spondylosis].
abstract: The aim of present study was to characterize the association between prevalence of vertigo and age, grade of radiological changes and positional vertebral (VA) and basilar artery (BA) flow lesion in patients with cervical spondylosis. We examined 80 patients with radiological evidence of cervical spondylosis. Forty patients complained positional vertigo. Patients with neurological symptoms were excluded from the study. ENG was used to exclude patients with another causes of vertigo. TCD evaluations of the distal part of VA and the proximal part of BA were performed with a 2-MHz probe via the suboccipital window. We showed significant and independent association between prevalence of vertigo and age, grade of radiological changes, and positional vertebral and basilar artery flow lesion velocity in multivariate logistic regression model. Spondylotic-induced VA compression may be the reason of decreased blood flow velocity in the basilar artery during head rotation, causing positional vertigo.
