[Doppler ultrasonography in the diagnosis of diseases of the supra-aortic trunks].
Systematic examination of the upper aortic arch vessels by direct Doppler ultrasonography of the common and internal arteries is proposed, together with calculation of the flow rate, pressure-perfusion index, carotid ratio, and carotid distensibility index on a systematic basis. Obligatory compression movements to evaluate the several supplementary pathways in the case of disease are also recommended to complete the examination.
