应用彩色多普勒血流显像技术对５０例椎动脉病变患者进行检查分析。结果可见椎动脉颅外段的异常表现：（１）椎动脉内径变细、走行异常、管腔有异常回声２８例，占５６％。（２）脉冲多普勒异常４３例，占８６％。（３）彩色多普勒血流显像异常１８例，占３６％。根据二维超声切面，结合彩色血流显像，综合判断脉冲多普勒所测定血流参数对判断椎动脉颅外段病理及机能状态，特别是对判断椎动脉供血不足的诊断有重要价值
Fifty patients with vertebral artery lesions were examined by color Doppler flow imaging. The results showed abnormalities in the extracranial segments of the vertebral artery: (1) The diameter of the vertebral artery became thin and abnormal. There were 28 cases of abnormal echo in the lumen, accounting for 56%. (2) Pulse Doppler abnormalities in 43 cases, accounting for 86%. (3) Color Doppler flow imaging abnormalities in 18 cases, accounting for 36%. According to two-dimensional ultrasonography, combined with color flow imaging, judging the blood flow parameters determined by pulsed Doppler to determine the pathological and functional status of extracranial segments of vertebral artery, especially for the diagnosis of vertebral artery insufficiency
