Unilateral carotid stenosis and impaired cerebral hemispheric vascular reserve.


Single photon emission computed tomography (SPECT) scanning with 99TcHMPAO (Ceretec) was used to demonstrate regional cerebral blood flow (rCBF) in sixteen patients with hemodynamically significant unilateral carotid stenosis. All patients were demonstrated by cerebral computed tomography to be without cerebral infarction. When dysautoregulation was induced… (More)
