Overview of Cerebrovascular Diseasestitute 80–85% of all strokes. It has been estimated that ≥50% carotid stenosis may be responsible for up to 25% of all ischemic strokes. The common carotid bifurcation and the proximal internal carotid artery account for ≥50% of the lesions. The work-up of patients presenting with asymptomatic caro

Ultrasonic Characterization of Carotid Plaques and Its Clinical Implications the risk of stroke increases with increasing grades of stenosis, and as a result a stenosis of ≥80% is used by many surgeons as an indication for surgery, this subgroup does not contain the majority of strokes that will subsequently occur. In addition, because the severity of stenosis cannot identi

Role of Duplex Ultrasound in Carotid Screeningccessful treatment of acute stroke is challenging. Therefore, the principal strategy against cerebrovascular disease and its role in causing ischemic stroke remains primary stroke prevention. Atherosclerotic plaque in the carotid artery causes a substantial proportion of ischemic strokes and is easi
