Carl, a 28-year-old patient, has a history of epilepsy with recurrent seizures. His seizures are intolerable even with medication management. He does not experience non-epileptic seizures, which was confirmed by EEG recordings. Today he underwent an open procedure for implantation of cranial nerve neurostimulator electrode array, which was coiled around the vagus nerve. The pulse generator was connected to the neurostimulator array, tested, and repositioned to ensure maximum effectiveness. The pulse generator was placed and sutured into a created subcutaneous pocket. Again, the system is tested to ensure proper functionality. The subcutaneous tissues and skin are closed with deep sutures and skin staples. Carl tolerated the procedure well and was returned to the recovery suite in stable condition.
