Phenomenology of neurophysiologic changes during surgical treatment of carotid stenosis using signal analysis

Abstract

HighlightsSignal processing of the SSEP obtained during treatment of carotid artery disease.Differences between control and unoperated and operated sides.Differences between treatment with open or endovascular approach.

Perioperative Stroke Detected Using Novel SSEP Analysis

“…1 In a previous report, we described a new method of analyzing the SSEP (and any neurophysiological waveform). 2 We showed that, in cases in which there were no neurological changes during carotid surgery (open or endovascular) and no changes in the SSEP according to the classical alert criteria, the new technique showed differences between stenting and endarterectomy and differences between patients undergoing lumbar spine surgery and those with symptomatic carotid stenosis requiring surgery. In particular, we measured the velocity of the upswing of the N20.…”
