As carótidas para os cardiologistas.

the internal carotid artery and the ratio of the peak systolic velocity in the internal carotid artery to that in the ipsilateral common carotid artery correlate with angiographically deter- mined stenosis.
Typically, 2 categories of internal CAS severity are defined by ultrasound, one (50% to 69% stenosis) that represents the inflection point at which flow velocity accelerates above normal because of atherosclerotic plaque and the other (70% to 99% stenosis) representing more severe nonocclusive disease. Subtotal arterial occlusion may sometimes be mis- taken for total occlusion, and it is sometimes difficult to distinguish 70% stenosis from less severe stenosis, which supports the use of corroborating vascular imaging methods in equivocal cases.

Método de escolha para diagnóstico de Ateromatose nas Carótidas: Doppler.

Na dúvida, Angiotomo.
