title: [Combined use of duplex sonography and CW Doppler in diseases of the carotid arteries].
abstract: 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.
