Within what time frame do 80% of clamp-related EEG changes during CEA occur?

The time frame during which 80% of clamp-related EEG changes occur during Carotid Endarterectomy (CEA) is documented to be within the first minute. This rapid onset of changes is significant because it allows for real-time monitoring of the brain's response to clamping of the carotid artery, which is crucial for minimizing the risk of ischemic damage. Surgeons and monitoring teams rely on this early detection to make timely interventions, such as modifying blood flow or utilizing techniques to protect the brain, including shunting. The clinical importance of identifying potential neurological complications as swiftly as possible is underscored here, and understanding this timeline reinforces the need for continuous and vigilant EEG monitoring during such procedures.
