33. Intraoperative neurophysiological monitoring of brain perfusion during cardiac surgery in patients with asymptomatic internal carotid stenosis
Asymptomatic internal carotid (ICA) stenosis is one of documented risk factors of perioperative ischemic stroke (IS) in cardiac surgery. There is no strict consensus in benefit of prophylactic carotid endarterectomy (CEA) in asymptomatic ICA stenosis to reduce intraoperative IS. Median somatosensory evoked potentials (SEP) is reliable tool for intraoperative neurophysiological monitoring (IONM) of brain perfusion during CEA.

11. “Two is better than one”? Simultaneous monitoring of multichannel somatosensory evoked potentials and electroencephalogram during carotid endarterectomy
In carotid endarterectomy (CEA), EEG and somatosensory evoked potentials (SEPs) are the most commonly used monitoring techniques to prevent perioperative stroke. However, which of these methods is the most appropriate is not definitely established. Here we evaluated retrospectively simultaneous EEG and SEP recordings. Our CEA series was analyzed backward to identify 30 patients requiring carotid shunt. Shunting was performed in 7.1% of 420 consecutive CEA over a 20-month period. All CEAs were continuously monitored by multi-channel EEG and SEPs before, during and 20min following carotid cross-clamping. The most reliable SE...
