Case report demonstrates effective ischemic tolerance assessment in pediatric giant serpentine aneurysm, highlighting surgical implications.
Objective: Giant serpentine aneurysms (GSAs) are a rare subtype of giant intracranial aneurysms characterized by partial thrombosis and a tortuous serpentine vascular channel. We report a case of pediatric GSA of the right internal carotid artery (ICA) in which ischemic tolerance was assessed using balloon test occlusion (BTO) with motor-evoked potential (MEP)/somatosensory-evoked potential (SEP) monitoring under general anesthesia, followed by parent artery occlusion (PAO).
