Screening of carotid arteries by noninvasive duplex scanning.
This paper has reported the accuracy of the duplex scanner in diagnosing occlusive disease of the carotid artery. Patients who present with vague neurologic symptoms, syncopal episodes, or asymptomatic carotid bruits are candidates for this type of study to determine the presence of significant stenosis. Other indications include the continuing assessment of known lesions and postoperative results in patients who have had endarterectomies.
