Abstract
The adverse consequences of carotid atherosclerotic plaques are manifest through two effects on brain perfusion: 1) embolism from intimal ulcerations to the brain and eye, 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.
