title: [Possibility of errors in conventional Doppler sonography of the carotid arteries].
abstract: Results of Doppler sonography and angiography were compared in 100 consecutive patients with ischaemia in the area of carotid arterial supply. In 15 there were important differences. Three Doppler "occlusions" were angiographically demonstrated to be carotid arterial stenoses; significant additional information was provided by angiography in two patients with stenoses at the origin of the internal carotid artery, while in ten--despite unremarkable Doppler findings--angiography revealed disease in the carotids.
