Event Description

It was reported by a surgeon that high lead impedance was found after replacement of a patient's generator. The surgeon found that the lead was twisted near the generator site, and also that the patient had a damaged vagus nerve and a neuroma proximal of the lead next to the fixation area. The surgeon indicated that the patient was known to be a twiddler and it is suspected that the patient twisted the generator (as seen during surgery). The patient was described to be spastic and severely mentally disabled in accordance to the surgeon. X-rays were taken of the patient prior to surgery and no anomalies were noted on the review according to the treating neurologist.
