Experience With a Noninvasive Evaluation for Cerebral Vascular Disease

Abstract

This report describes a newly developed noninvasive method for extra cranial cerebrovascular evaluation. Two hundred consecutive cases were stud ied at the Massachusetts General Hospital and matched with clinical and angiographic findings. There were three false negative and five false positive results. Two ulcerated plaques without stenosis were not detected. Management routes for different groups of patients with central nervous system symptoms are outlined. We emphasize the usefulness of monitoring postoperative ophthal mic artery pressure to aid in the early detection of carotid occlusion in patients developing neurologic symptoms following carotid endarterectomy.
