Abstract

There has been a growing interest in using intraoperative neuromonitoring to reduce the incidence of stroke and paralysis in major vascular interventions. Electroencephalography, various neurophysiological evoked potential measurements, transcranial Doppler, and near-infrared spectroscopy are some of the modalities currently used to detect neural injuries. A good understanding of these modalities and their interactions with anaesthesia is important to maximize their value and to allow meaningful interpretation of their results. In view of the inter-individual differences in anatomy, physiological reserves, and severity of pathological processes, neuromonitoring may be a valuable method to evaluate the well-being of the nervous system during and after surgical interventions. In this review, we summarize some of their applications, efficacies, and drawbacks in major carotid and aortic surgeries.
