Neurocognitive Function After Carotid Thrombendarterectomy

Previous studies did not reach a consensus on the influence of the type of anesthesiologic procedure and monitoring, during carotid thrombendarterectomy, on perioperative complications and cognitive outcomes. The aim of this study is the optimization of brain perfusion during the vascular carotid clamp using multimodal monitoring. We assume that standardized monitoring techniques and a better selection of cognitive tests will allow a more accurate assessment of subclinical cognitive deficits.
