Value of the non-invasive cerebrovascular laboratory in diagnosis of extracranial carotid artery disease. An analysis of 159 studies in 157 patients.
Non-invasive vascular testing has proven to be an effective means of identifying patients with significant extracranial carotid artery disease. Such tests can yield valuable physiologic data in patients with TIAs and can identify patients with soft signs who may have significant carotid artery disease and who may be candidates for angiography. It may be an effective means of reducing the number of negative carotid angiograms.
