[Chinese expert consensus on intraoperative neurophysiological monitoring of intracranial aneurysms (2023 edition)].

Intracranial aneurysm is a common disease in neurosurgery, and intraoperative vascular injury causes postoperative ischemic complications that seriously influence patient prognosis. Intraoperative neurophysiological monitoring (IONM) enables effective identification of early intraoperative ischemia and thus reduces related complications. The Clinical Neurophysiology Committee of the Chinese Research Hospital Association and the Neurosurgeons Branch of the Chinese Medical Doctor Association organized national experts in neurophysiology and cerebrovascular disease to develop this expert consensus based on a review of published guidelines, consensuses and clinical evidence both at home and abroad, and after Delphi expert consultation. A consensus was formed on four aspects, including commonly used IONM techniques and parameter settings, perioperative preparation and interpretation of results, the value of intraoperative electrophysiological monitoring of aneurysms at different sites, and electrophysiological monitoring in special cases. Moreover, according to level of evidence recommended by GRADE criteria, nine recommendations were put forward from the above four aspects to provide a reference for clinical intracranial aneurysm intraoperative neurophysiological monitoring practice. 颅内动脉瘤是神经外科常见疾病，术中血管损伤引起术后缺血性并发症，严重影响患者预后。术中神经电生理监测（IONM）能有效识别早期术中缺血，减少相关并发症。中国研究型医院学会临床神经电生理专业委员会和中国医师协会神经外科医师分会神经电生理学组组织了全国神经电生理及脑血管病方面的专家，在回顾国内外已发布的指南共识和临床证据基础上，经过德尔菲专家咨询，制定了本专家共识。形成了常用的IONM技术及参数设置、围手术期准备与结果解读、不同部位动脉瘤术中电生理监测价值和特殊情况下电生理监测四个方面的共识。并根据GRADE证据等级标准，从上述四个方面给出了9条推荐意见，为临床颅内动脉瘤术中神经电生理监测实践提供参考。.
