Carotid endarterectomy is a common procedure as a secondary prevention of stroke, and is often performed with selective shunting. Although various EEG parameters have been proposed to determine if the brain is at risk during carotid artery clamping, the common procedure is still the visual assessment of the EEG. Here, we propose an extension to the previously described brain symmetry index (BSI) [van Putten M, Peters J, Mulder S, de Haas J, Bruijninckx C, Tavy D. A brain symmetry index (BSI) for online EEG monitoring in carotid endarterectomy. Clin Neurophysiol 2004, 115(5), 1189-94.], as an additional quantitative criterion for shunt need in carotid endarterectomy. ⋯ Quantitative real-time EEG analysis will assist in the EEG interpretation for selective shunting in carotid endarterectomy.
