Intraoperative monitoring of somatosensory and visual evoked potentials for detecting posterior cerebral artery infarction during anteromesial temporal resection: Suyeon Seo, Dong Jun Kim, Chae Young Lee; Ann Clin Neurophysiol 2020;22(2):104-108.

We performed intraoperative neurophysiological monitoring (INM) during anteromesial temporal resection (AMTR) in a patient with lesional temporal lobe epilepsy. INM revealed a sudden decrease in N20 waves in somatosensory evoked potentials (SSEPs) and poor P100 waves in visual evoked potentials (VEPs). These changes developed after applying electrocoagulation in the right mesial temporal areas. Postoperative brain magnetic resonance imaging demonstrated right thalamic and medial occipital infarctions. SSEPs and VEPs monitoring can be useful for detecting posterior cerebral artery infarction in AMTR.
