In a prospective study 451 patients were examined with extracranial CW-Doppler sonography (mastoidal slope), suboccipital transcranial Doppler sonography and colour-coded duplex sonography to evaluate unusual vertebral arteries (hypoplasia, stenosis and occlusion). Colour duplex sonography was used as reference method. CW-Doppler sonography had a sensitivity of 100% and a specificity of 27% for the detection of an unusual vertebral artery. For transcranial Doppler sonography these values are 38% and 58%. Our study showed that CW-Doppler is a useful screening examination for identifying pathological findings of vertebral arteries. In case of abnormalities in CW-Doppler, duplex sonography, especially colour-coded duplex sonography, should be added.
在一项前瞻性研究中，对451例患者进行了颅外连续波多普勒超声检查（乳突斜坡）、枕下经颅多普勒超声检查和彩色编码双功超声检查，以评估椎动脉异常情况（发育不全、狭窄和闭塞）。彩色双功超声检查用作参考方法。连续波多普勒超声检查检测椎动脉异常的敏感性为100%，特异性为27%。经颅多普勒超声检查的相应值分别为38%和58%。我们的研究表明，连续波多普勒超声检查是识别椎动脉病理表现的一种有用的筛查方法。如果连续波多普勒超声检查出现异常，应增加双功超声检查，尤其是彩色编码双功超声检查。
