It is generally agreed that at least one-third of Strokes arise from atherosclerotic lesions developing on the extracranial arterial channels. The bifurcation of the common carotid artery in the neck is a site particularly prone to develop plaques. The adverse effects of carotid atherosclerotic plaques are manifest through two effects on brain perfusion: 1), embolism to the brain and eye from intimai ulcerations, and 2), a reduction in hemispheric flow. The purpose of this chapter is to understand the local Doppler velocity signals and the local pressure-flow relationships associated with stenosis of the carotid arteries in order to quantitate the degree of carotid narrowing and its effect on brain perfusion.
