“…Some acute or delayed ischemic complications have been reported because of the coverage of side branches by neck-bridging or flow diverter stents, especially involving the ophthalmic artery and AchA ( 19 , 20 ), and visual impairments are often observed after such endovascular procedures ( 21 , 22 ). Neurophysiological monitoring of SSEP and MEP in neuro-endovascular treatment has proven that SSEP and MEP monitoring during endovascular aneurysm treatment can reliably assess pyramidal tract function and improve clinical outcomes ( 12 , 18 , 23 ). The possible efficacy of intraoperative VEP monitoring has been reported for parasellar, temporal, parietal, and occipital brain tumors, allowing at minimum the detection of new quadrantanopia ( 13 , 24 , 25 ).…”
