Hemodynamic changes of severe carotid atheromatosis pre and post endarterectomy in the case of a coronary patient with ischemic stroke [PDF]

Romanian Journal of Neurology, 2013
Nearly 25%-30% of ischemic strokes are due to atherosclerosis of the carotid bifurcation. Cerebrovascular reactivity (CVR) is an indicator for testing hemodynamic status of cerebral circulation.
