Abstract Somatosensory, visual, and auditory evoked potentials have been used to monitor neurological function in patients under general anesthesia. This paper describes the preservation of useful hearing in three patients with cerebellopontine angle tumors. In each case, cochlear function was...
Abstract The author describes the surgical treatment of 14 patients in whom angiography demonstrated total occlusion of the internal carotid artery (ICA) associated with stenosis at the origin of the ipsilateral external carotid artery (ECA). Each patient underwent ECA endarterectomy followed by...
Abstract We present a prospectus on the use of computer graphics for the three-dimensional reconstruction and visualization of brain lesions from computed tomographic head examinations, including an algorithm that utilizes surface contour information to reconstruct and display three-dimensional...
Abstract Cortical somatosensory evoked potentials (SSEPs) reflect the functional integrity of somatosensory pathways from the site of stimulation to the primary somatosensory cortex. We used intraoperative monitoring of cortical SSEPs to determine whether the right anterior cerebral artery...

Abstract A computed tomographic-stereotactic system based on the Leksell stereotactic frame has been used to implant radioactive 125I sources into (28 procedures) or to biopsy (2 procedures as biopsy only, 2 in conjunction with the implantation of a radioactive source) malignant brain tumors. In...
Abstract Eighty-eight patients with brain ischemia underwent cerebral angiography and measurement of regional cerebral blood flow (rCBF) after 133Xe inhalation. A fast compartment flow rate and an initial slope index were computed for each detector and for each hemisphere. The clinical...
Abstract A case of congenital lumbar stenosis producing lower extremity spasticity and bladder dysfunction in a young child is presented. Myelography demonstrated a marked stenosis of the spinal canal at L-2, L-3, and decompressive laminectomy resulted in a marked improvement in symptoms. A...
