The patients were premedicated and sedated to a level that allowed awake neurologic assessment. Intraoperative neurologic changes were recorded and all patients were examined postoperatively by an independent anesthesiologist to record postoperative neurologic outcome. RESULTS: Trial carotid artery cross clamping resulted in 24% ..
