obstructive sleep apnea, seizures, vagus nerve stimulation
An 11-year-old female presents to the sleep clinic for evaluation for possible sleep-disordered breathing (SDB). She has a history of frequently intractable seizures for which she was tried on multiple antiepileptic medications. She had vagus nerve stimulation (VNS) implantation two years ago to treat her focal seizures. Nine months later, her seizures were controlled, but the family raised concerns about louder snoring and more frequently witnessed apneas. She had polysomnography (PSG) that showed severe obstructive sleep apnea (OSA) related to her VNS. The patient was diagnosed with SDB secondary to electrical activations of the implanted VNS. We describe an epilepsy patient whose case illustrates the possible respiratory complications (primarily OSA) associated with VNS. We will discuss the possible mechanisms of VNS related SDB and the importance of screening for SDB and advocate for a PSG both before and after VNS implantation.
