ROC Curve Analysis of Electrophysiological Monitoring and Early Warning During Intracranial Aneurysm Clipping.

Objective To explore the safe duration of temporary clipping of the parent artery under intraoperative electrophysiological monitoring. Methods The clinical data of 97 patients who underwent intracranial aneurysm clipping under electrophysiological monitoring in the Department of Neurology, Affiliated Hospital of Qingdao University from June 2019 to June 2020 were retrospectively analyzed. The safety duration of temporary clipping was analyzed using receiver operating characteristic (ROC) curves, and the results were validated in clinical data. Results Temporary clipping during operation (P Conclusion Temporary intraoperative block is the risk factor for cerebral ischemia after operation. In this study, the temporary clipping time of the parent artery should not be longer than 6 minutes, and there is approximately 1 minute to adjust the current procedure after the electrophysiological warning to restore the baseline of intraoperative electrophysiological monitoring.
