Endoscopic hemispherotomy: an illustrative video

Abstract

Endoscopic surgery has brought about a paradigm shift in the field of neurosurgery. It provides a panoramic view, heightened illumination, magnification, and the unique ability to navigate corners, all of which significantly enhance surgical precision. Endoscopic hemispherotomy is a procedure that allows functional disconnection of the abnormal hemisphere from the ipsilateral basal ganglia, thalamus, and contralateral brain. This video article gives an overview of endoscopic hemispherotomy for a case of drug-refractory epilepsy due to an old middle cerebral artery infarct. It also showcases the value of functional magnetic resonance imaging in deciding the surgery.
