Abstract：Objective To explore the application of neuroelectrophysiological monitoring in endovascular treatment of intracranial aneurysms.Methods A total of 112 patients with intracranial aneurysms treated in Ganzhou Hospital Affiliated to Nanchang University from October 2015 to June 2018 were selected as the research objects.They were divided into two groups according to whether neuroelectrophysiological monitoring was used during the operation.There were 42 patients in the monitoring group and 70 cases in the non-monitoring group.The somatosensory evoked potential (SEP),motorevoked potential (MEP),brainstem auditory evoked potential (BAEP) and scalp electroencephalography (EEG)were conducted depending on the location of the aneurysm and its associated vascular territory,the treatment outcome was evaluated using modified Rankin scale (mRS) score at follow-up.The postprocedural neurological deficits within 24 hours after operation and the prognosis at 6 months after operation in two groups were compared and analyzed..Results Intraoperative changes in SEP tracings alone were found in 8 patients in the monitoring group,SEP and EEG changes were noted in 2 patients.SEP,MEP and EEG changes were noted to be simultaneous in 1 patient.The prevalence of postprocedural neurological deficits within 24 hours after operation in the monitoring group was lower than that in the non-monitoring group,there was statistically signifcant difference (P<0.05).No statistical difference was found in the prognosis at 6 months after operation between the two groups (P>0.05).Conclusion In the endovascular treatment of intracranial aneurysms,multimodal neuroelectrophysiological monitoring can timely reflect brain tissue ischemia,improve the safety of surgery,and reduce the occurrence of postprocedural neurological deficits after operation.
