Model Number 103
Event Date 04/27/2010
Event Type  Injury  
Event Description

A patient reported that during implant surgery, the surgeon implanted the vns generator on the right side of the patient's chest as the patient was implanted with a pacemaker on the left side. During implant, the patient experienced asystole and had to be resuscitated. During surgery, the patient also experienced a large seizure when the vns was programmed on and now the patient is having more seizures than she did prior to being implanted with the device. The patient also stated that the device is pushing up against her skin which causes pain while dressing. Per the patient, the surgeon stated that the generator battery may have been used up during surgery, and he was unsure if the device was still functioning. Follow up with the neurologist revealed that the patient has a history of arrhythmia. The generator is registering magnet swipes. He does not know if the increase in seizures is above baseline levels. The protrusion response was that the device looks no different from any other patient other than it being on the right side. He will do a symptomatic therapy for the pain and possible consultation with a surgeon for a revision of the implant if desired by the patient. He does not know of any trauma or manipulation. Good faith attempts to obtain additional information from the surgeon have been unsuccessful to date.
