740 patients with findings of cerebrovascular insufficiency were investigated by duplex sonography and frequency-analysing cw doppler. In 620 pathological arteries not stenosing lesions of the carotid bifurcation were found most frequently (93%). In 35% moderate-severe stenoses of the a. carotis interna were diagnosed. The advantage of duplex sonography and cw doppler in combination is the addition of both methods, so that a very reliable diagnosis of the extracranial carotis is possible.
对740例有脑血管供血不足表现的患者进行了双功超声检查和频率分析连续波多普勒检查。在620条病变动脉中，最常见的是非狭窄性颈动脉分叉病变（93%）。35%的患者被诊断为颈内动脉中度至重度狭窄。双功超声检查和连续波多普勒检查相结合的优点是两种方法相辅相成，从而能够对颅外颈动脉进行非常可靠的诊断。
