Intraoperative neurophysiologic monitoring (IONM) changes associated with a case of delayed thalamic infarct: Implications for postoperative management. Journal of clinical neuroscience : official journal of the Neurosurgical Society of Australasia Ghavami, F., Choudhri, O., Marks, M., Lopez, J. R. 2017


Treatment of cerebral aneurysms poses a risk of cerebral hemorrhage and/or ischemia; these potential sequelae are usually associated with changes in intraoperative neurophysiologic monitoring (IONM) modalities. Our case demonstrates a patient with significant changes in IONM during the treatment of a right posterior cerebral artery aneurysm who did not develop neurologic deficits until three days postoperatively. IONM changes can represent a guide in postoperative patient management and may pose grounds for closer monitoring of patients with IONM changes that do not develop immediate postoperative deficits.
