Randomized trial assesses stroke risk in patients undergoing carotid endarterectomy, indicating EEG changes may highlight higher risk groups.

This research aims to determine the correlation between contralateral stenosis, EEG changes, and stroke risk during carotid endarterectomy.
Performed 293 carotid endarterectomies without shunt and monitored EEG.
Categorized contralateral stenosis into three groups: <70%, 70-99%, and occlusion.
Analyzed perioperative stroke and immediate postoperative deficits.
Observed six perioperative strokes (2.0%) and two deaths (0.7%).
Major EEG changes were noted in 14.3% of patients with significant contralateral stenosis versus 5.1% without (P<0.025).
The incidence of immediate postoperative deficits was 18.2% in patients with major EEG changes compared to 1.8% without (P<0.005).

Redekop et al. (1992) studied this question.
