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, especially complaining of vertigo.
Every patient with high-grade cervical spondylosis, especially complaining of vertigo, should be examined by using TCD (transcranial Doppler) with head rotations. In case of positional blood flow reduction during head rotation, further angiographic examination should be undertaken so as to plan suitable treatment.

我们研究的目的是明确颈椎病患者基底动脉（BA）血流速度与年龄、放射学改变程度、眩晕患病率以及头部旋转后椎动脉（VA）血流速度降低之间的关系。
在学术性神经耳科学领域进行了一项前瞻性对照研究。我们检查了80例有颈椎病放射学证据的患者。40例患者主诉位置性眩晕持续超过6个月。对患者进行头部旋转时的经颅多普勒超声检查。
我们发现颈部旋转后基底动脉血流速度与年龄、眩晕患病率、放射学改变程度以及位置性椎动脉血流病变之间存在显著关联。
颈椎病导致的VA受压可能是头部旋转时基底动脉血流速度降低的原因，这对老年患者可能尤为重要，尤其是那些主诉眩晕的患者。
每例重度颈椎病患者，尤其是主诉眩晕者，均应进行头部旋转时的经颅多普勒（TCD）检查。若头部旋转时出现位置性血流减少，应进一步进行血管造影检查，以便制定合适的治疗方案。
