We studied 130 patients, aged 20 to 81 years, with symptoms of tinnitus, vertigo or dizziness. Radiological examinations revealed degenerative changes in the cervical spines of all patients such as discopathy or osteophytes. Head and neck and neurological examinations ruled out other symptoms apart from vertebrobasilar artery flow insufficiency. The vertebrobasilar arteries were examined by means of a color Doppler ultrasonograph using duplex scanning. The correlation coefficient (CC) defining the relationship between the number of patients with abnormal blood flow and the total number of patients with radiologically confirmed changes in the cervical spine was 41.5%. When patients were separated by age, the value of the CC coefficient increased proportionally according to age, changing from 0 to 79.1%. Use of the Doppler ultrasonograph was found to be a safe and non-invasive diagnostic method that enabled us to assess the influence of degenerative changes in the cervical spine on hemodynamic disturbances in the inner ear and brain stem. Our findings demonstrated a pathological decrease of vertebral artery flow velocity in relationship to degenerative changes in the cervical spine.
我们研究了130例年龄在20至81岁之间、有耳鸣、眩晕或头晕症状的患者。放射学检查显示所有患者颈椎均有退行性改变，如椎间盘病变或骨赘形成。头颈部及神经系统检查排除了除椎基底动脉血流不足以外的其他症状。通过彩色多普勒超声仪采用双功扫描对椎基底动脉进行检查。定义血流异常患者数量与经放射学证实颈椎有改变的患者总数之间关系的相关系数（CC）为41.5%。当按年龄对患者进行分组时，CC系数的值随年龄成比例增加，从0变化至79.1%。结果发现，使用多普勒超声仪是一种安全且无创的诊断方法，它使我们能够评估颈椎退行性改变对内耳和脑干血流动力学紊乱的影响。我们的研究结果表明，椎动脉血流速度与颈椎退行性改变相关，呈病理性下降。
