- Abstract: Seizure following percutaneous endoscopic lumbar discectomy (PELD) is extremely rare. We report that generalized seizure occurred in a patient with radiating right leg pain after PELD under sevoflurane anesthesia. Cerebrospinal fluid (CSF) was detected from a dura tear in the operative field. On emergence from anesthesia, generalized tonic-clonic activity continued for approximately 2 minutes and the level of consciousness was decreased to a stuporous state. Under sedation, a pneumocephalus which was thought to be caused by the dura tear was evaluated with a brain computed tomography (CT) and a continuous slow wave was found on electroencephalography (EEG) without any epileptiform discharges. Eight hours postoperatively, the decreased level of consciousness recovered, and after 2 weeks, the patient was discharged without any neurologic sequealae. Clinicians should recognize the epileptogenic potential of sevoflurane and limit the maximum dose with avoidance of hypocapnia by hyperventilation. If an intracerebral lesion is accompanied, it may increase the possibility of the occurrence of seizure.
