Normal internal carotid velocity
WebSide-to-side differences of common carotid artery velocities are present in occlusion of the internal carotid artery or severe stenosis but are less reliable for the differentiation between 60% and 70% stenoses. Web1 de fev. de 1995 · Doppler velocity ratios for ICA/CCA are 0.4 to 0.7 for normal vessels 9 10; in the assessment of carotid atheroma, a velocity ratio >1.5 is considered significant for stenosis >50%. 10 In the development of CSI, we have adopted the ICA/CCA ratio of 1:1.2.

Background: Carotid artery disease is most often seen in hypertensive patients and in patients with diabetes mellitus. More than 50% stenosis of extra cranial internal carotid arteries is linked with about 8–15% of ischemic strokes. The incidence of carotid artery stenosis (CAS) among diabetic patients is rising as compared to non-diabetic …
