Abstract：
UNASSIGNED: The present study aimed to determine the incidence of intraprocedural visual-evoked potential (VEP) changes and to identify correlations with intraprocedural ischemic complications during endovascular treatment in patients with intracranial aneurysm related to visual function.
UNASSIGNED: This study analyzed data from 104 consecutive patients who underwent endovascular coil embolization to treat intracranial aneurysms related to visual function under VEP and transcranial motor evoked potential (MEP) monitoring. We analyzed associations between significant changes in MEP and VEP, defined as a >50% decrease in amplitude, and both intraprocedural complications and postoperative neurological deficits. Factors associated with postoperative neurological deficits were also assessed.
UNASSIGNED: Treated aneurysms were predominantly located in the internal carotid artery (95%). Five (5%) were located in the posterior cerebral artery (PCA). Significant decreases in intraprocedural VEP occurred in four patients (4%), although one of those four patients did not show concomitant MEP decreases during procedures. Immediate salvage procedures avoided postoperative visual disturbances. All VEP decreases were transient and not associated with postoperative visual impairment. One of three cases who underwent intraoperative balloon occlusion test showed tolerance to balloon occlusion of the proximal PCA under VEP assessment; parent artery occlusion was performed without postoperative visual disturbance in that case.
UNASSIGNED: Although significant VEP decreases occurred 4% during neuro-endovascular aneurysm treatment related to visual function, intraprocedural VEP monitoring identifies ischemic changes associated with visual pathways and facilitates prompt initiation of salvage procedures.

摘要：
UNASSIGNED：本研究旨在确定颅内动脉瘤患者术中视觉诱发电位（VEP）变化的发生率，并确定与视觉功能相关的血管内治疗过程中缺血并发症的相关性。
UNASSIGNED：这项研究分析了104例连续患者的数据，这些患者接受了血管内弹簧圈栓塞治疗，以治疗与VEP和经颅运动诱发电位（MEP）监测下的视觉功能相关的颅内动脉瘤。我们分析了MEP和VEP的显著变化之间的关联，定义为振幅下降>50%，术中并发症和术后神经功能缺损。还评估了与术后神经功能缺损相关的因素。
未经证实：治疗的动脉瘤主要位于颈内动脉（95%）。5％（5％）位于年夜脑后动脉（PCA）。术中VEP显著下降4例（4%），尽管这4例患者中的1例在手术过程中没有出现伴随的MEP下降.立即抢救程序避免了术后视力障碍。所有VEP降低都是短暂的，与术后视力障碍无关。在VEP评估下，接受术中球囊闭塞测试的三例患者中的一例表现出对近端PCA的球囊闭塞的耐受性；在这种情况下，进行了父母动脉闭塞而没有术后视力障碍。
UNASSIGNED：尽管在与视觉功能相关的神经血管内动脉瘤治疗期间发生了4％的明显VEP下降，术中VEP监测可识别与视觉通路相关的缺血变化,并有助于迅速启动抢救程序.
