  • Title: [Methodologic aspects and criteria for evaluating extracranial carotid Doppler sonography].
    Author: Podhaisky H, Hänsgen K.
    Journal: Z Gesamte Inn Med; 1989 Feb 01; 44(3):88-91. PubMed ID: 2658381.
    Abstract:
    Doppler-sonographic and internal angiological findings of 57 patients with extracranial stenosis or obliteration of the internal carotid artery were evaluated. On the basis of the audio-signals and Doppler speed curves derived from the supratrochlear artery, the common and internal carotid arteries haemodynamically relevant extracranial obstructions of the vascular system could be objectified and judged with regard to their collateral compensation. Diagnostically valuable were the comparison of the sides and the additional calculation of the indices of the resistance. The Doppler sonography of the carotid artery should be used within the clarification of a cerebrovascular insufficiency and before every invasive diagnostics.
