NON-ATHEROMATOUS STENOSIS AND OCCLUSION OF THE INTERNAL CAROTID ARTERY AND ITS MAIN BRANCHES

Atherosclerosis is by far the most common cause of stenosis and occlusion of intracranial and extracranial arteries in the western world. With increasing use of cerebral angiography, other stenoses and occlusions will be encountered with greater frequency than heretofore. Analysis of 7,000 carotid angiograms over a period of 8 years has revealed a wide variety of pathologic conditions responsible for stenosis and occlusion of the internal carotid artery and its branches; 140 such cases have been classified.
