彩色多普勒超声显像对椎动脉型颈椎病的诊断及相关问题的研究

Color Doppler Ultrasonography in the diagnosis of cervical spondylosis of vertebral artery type and a discussion of the related problems

目的 探讨彩色多普勒超声显像技术及诱发电位测试对椎动脉型颈椎病的诊断价值。方法 ①对 4 0例健康者正常组和 4 0例患者患病组的椎动脉进行彩色多普勒超声检测 ,测量椎动脉管径、峰值流速、阻力指数 ,同期进行CT或MRI检查 ;②分别对患病组和正常组各 16例做诱发电位测试 ;③测量 4 0具尸体椎动脉管径。结果 ①椎动脉型颈椎病患者椎动脉管径较正常组明显变细 ,峰值流速减慢 ,阻力指数增大。②诱发电位测试患病组中枢感觉传导时间 (CSCT)和N2 0 潜伏期较正常组明显延长。结论 彩色多普勒超声显像对椎动脉型颈椎病有较高的诊断价值 ,可进行定性定量诊断。诱发电位测试可对本病提供新的诊断依据。

Objective To discuss the diagnostic value of color doppler ultrasonography and somatosensory evoked potentials in cervical spondylosis of vertebral artery type Methods ①Vertebral arteries of 40 healthy volunteers and 40 patients were examined by ultrasound?CT or MRI simultaneously.The ultrasonic measurements included diameter?peak systolic velocity and resistance index;②16 healthy volunteers and 16 patients were examined by somatosensory evoked potentials;③Vertebral arteries of 40 corpses were calibrated.Results ①Diameters of vertebral arteries were obviously smaller?peak systole velocities were slower and resistance indexes were higher in patients with cervical spondylosis compared with those of volunteers.②Central sense conductive time(CSCT) and latent period of N 20 in patients were elongated apparently compared with those of volunteers.Conclusion The diagnostic value of color doppler ultrasonography in cervical spondylosis of the vertebral artery type is quite apparent and it is able to demonstrate qualitative and quantitative data.Somatosensory evoked potentials provides a new diagnostic method for this disease.
