Key result
EEG monitoring and selective shunting during CEA linked to ~52% lower major neurological morbidity and mortality.
Why the study?
Does intraoperative EEG monitoring and selective shunting reduce neurological morbidity and mortality in patients with symptomatic carotid occlusive disease undergoing elective carotid endarterectomy?
Observational (n=172)
Does intraoperative EEG monitoring and selective shunting reduce neurological morbidity and mortality in patients with symptomatic carotid occlusive disease undergoing elective carotid endarterectomy?
Absolute Event Rate: 1.1% vs 2.3%
Routine intraoperative EEG monitoring with selective shunting during carotid endarterectomy may reduce the need for shunts and lower perioperative neurological morbidity and mortality.
May support EEG-guided selective shunting to lower neurological morbidity; leaves open confirmation by randomized trials.
Since controversy continues concerning the value of routine electroencephalographic (EEG) monitoring and selective carotid bypass shunting, we reviewed the neurological morbidity and mortality following elective carotid endarterectomy in 172 patients with symptomatic carotid occlusive disease. The use of EEG monitoring and selective shunting was associated with a reduction in the frequency of carotid shunts (49 to 12%) and a decline in combined major neurological morbidity and mortality (2.3 to 1.1%). We conclude that the routine use of intraoperative EEG monitoring is a valuable procedure, particularly in patients at high risk for perioperative neurological complications.

Cho et al. (1986) conducted an observational in Symptomatic carotid occlusive disease (n=172). Intraoperative EEG monitoring and selective shunting vs. No EEG monitoring / routine shunting was evaluated on Combined major neurological morbidity and mortality. Intraoperative EEG monitoring and selective shunting during carotid endarterectomy was associated with a decline in combined major neurological morbidity and mortality from 2.3% to 1.1%.
