儿童颈性眩晕患者的颈椎X线片及经颅多普勒超声特征

摘要

目的：分析颈性眩晕儿童的颈椎X线片及经颅多普勒超声(TCD)特征，探讨发病机理。方法对80例颈性眩晕儿童进行颈椎X线片及TCD检查，分析其特点。结果本组患儿的颈椎X线片异常主要为寰枢椎或/和C2、C3椎关节紊乱，可并发颈椎失稳、颈曲变直甚至颈曲反弓、颈轴侧弯；异常TCD表现以单支或多支动脉血流速度增快为主，少数表现为单支或多支动脉血流速度减慢及双侧血流速度不对称。结论儿童颈性眩晕的病变部位主要在寰枢椎或/和C2、C3椎，发病机制主要为寰枢椎或/和C2、C3椎间多种形式的关节紊乱。%Objective To analyze the features of cervical vertebra X-ray examination and transcranial Doppler (TCD) in children with cervical vertigo, and investigate the mechanism of the disease. Methods X-ray examination of cervical vertebra and TCD were performed on 80 children with cervical vertigo, and the features of the results were analyzed. Results The abnormal results of cervical X-ray examina-tion mainly showed atlantoaxial joint or/and C2, C3 vertebral joint disorders, some of which combined with cervical instability, cervical cur-vature straightened and even reverse curvature, cervical scoliosis. The abnormal results of TCD showed the blood flow velocity in single or multiple branch of artery increased mainly, some of which decreased or became asymmetrial. Conclusion The cervical vertigo in children may result from various kinds of disorders of the atlas, axis or/and C2, C3 vertebrae.
