What is Temporary Vessel Occlusion in Cerebral Aneurysm Surgery Guided by Direct Cortical Motor Evoked Potentials about?

## Background: Temporary clipping is an important tool in the vascular neurosurgeon's armamentarium. we routinely utilize intraoperative neurophysiological monitoring (ionm) for complex brain aneurysm surgery cases, relying on direct cortical motor evoked potential (dcmep) alerts to guide the duration of temporary clipping. previous studies have argued for relatively short and intermittent temporary clipping strategies. in this study, we sought to assess the maximal permissive temporary clipping time during complex aneurysm surgery. to do this, we assessed patient outcome in relation to temporary clip duration guided by dcmep. ## Methods: We queried our prospectively collected neuromonitoring database for anterior circulation aneurysm cases where temporary clipping was utilized by a single cerebrovascular surgeon between 2018 and 2021. operative and ionm reports were reviewed. patients in whom the duration of temporary clipping could not be determined were excluded. the operative strategy permissively allowed continuous temporary clipping as long as no neuromonitoring alerts were encountered. maximal permissive parent artery occlusion time (clip) was recorded as the longest duratio
