Symptomatic Carotid Artery Occlusion A Reappraisal of Hemodynamic Factors

摘要: Background Over the last several years evidence has accumulated that in addition to embolism, a compromised cerebral blood flow may play an important role causing transient ischemic attacks and stroke patients with occlusion of internal carotid artery. This is found both clinical features ancillary investigations, particularly measurements flow. Summary Review On basis 20 follow-up studies or minor associated occluded artery, annual risk was 5.5% (95% confidence interval [CI], 5.0% 6.0%), ipsilateral (distinguished 11 studies) 2.1% CI, 1.6% 2.8%). Patients as measured by positron emission tomography, single-photon CT, transcranial Doppler, stable xenon CT (six have even higher (all strokes: 12.5%; 95% 8.9% 17.6%; ipsil...
