What are the advantages and disadvantages of different methods for monitoring cerebral ischemia during carotid endarterectomy and stenting?
This review highlights the various modalities available for monitoring cerebral ischemia during carotid interventions, emphasizing the lack of a universal gold standard.
Awake monitoring may be underused in carotid procedures; leaves open need for standardized protocols.
Current therapy for carotid stenosis mainly includes carotid endarterectomy and endovascular stenting, which may incur procedure-related cerebral ischemia. Several methods have been employed for monitoring cerebral ischemia during surgery, such as awake neurocognitive assessment, electroencephalography, evoked potentials, transcranial Doppler, carotid stump pressure, and near infrared spectroscopy. However, there is no consensus on the gold standard or the method that is superior to others at present. Keeping patient awake for real time neurocognitive assessment is effective and essential; however, not every surgeon adopts it. In patients under general anesthesia, cerebral ischemia monitoring has to rely on non-awake technologies. The advantageous and disadvantageous properties of each monitoring method are reviewed.
