SUMMARY: Intraoperative neurophysiological monitoring is routinely used during the repair (endovascular or microsurgical) of @entity438 at major centers. There is a continued need of data sets from institutions with dedicated intraoperative neurophysiological monitoring services to further define the predictive factors of postoperative @entity51 . We retrospectively reviewed and analyzed our database of all @entity1 who underwent repair of @entity438 (endovascular or microsurgical). A total of 406 @entity1 underwent 470 procedures. The changes were noted during monitoring in 3.83% of the cases. Most of the changes were first detected in somatosensory evoked potential (88.89%) followed by brainstem auditory evoked potential (16.67%). Changes were completely reversible in 44.44%, only partly reversible in 22.22%, and irreversible in 33.33% of cases. Intraoperative neurophysiological monitoring changes demonstrated high sensitivity, specificity, and negative predictive value for postoperative @entity51 . The association between intraoperative neurophysiological monitoring changes and Glasgow outcome scale was significant for reversible changes compared against irreversible and partly reversible changes. Presence of any intraoperative neurophysiological monitoring modality change during repair of @entity438 may suggest a higher risk for postoperative @entity51 . Reversibility of the changes is a favorable marker, whereas irreversible changes are predictive of postoperative @entity51 with deterioration of Glasgow outcome scale on a longer follow-up.
