Key result
Sequential EEG and SSEP monitoring detects severe cerebral ischemia in ~2% of carotid endarterectomies.
Why the study?
Does sequential EEG and SSEP monitoring accurately identify severe cerebral ischemia during carotid endarterectomy?
Observational (n=255)
Does sequential EEG and SSEP monitoring accurately identify severe cerebral ischemia during carotid endarterectomy?
Sequential use of EEG and SSEPs during carotid endarterectomy provides complementary monitoring, as SSEPs can detect slow-onset cerebral ischemia missed by EEG.

May support sequential EEG-SSEP monitoring to detect missed ischemia in carotid endarterectomy; leaves open impact on perioperative outcomes.
Fiori et al. (1995) conducted an observational in Severe carotid stenosis (n=255). Sequential computerized two-channel EEG and SSEPs was evaluated on Changes referable to severe cerebral ischemia. Sequential monitoring with EEG and SSEPs during carotid endarterectomy detected severe cerebral ischemia in 1.96% of cases, with SSEPs identifying slow-onset ischemia despite a normal EEG pattern.
