Event Description

A vns programming physician reported to our consultant that they had a vns patient and after performing a normal mode and system diagnostic test the results indicated: high: limit: dcdc: 7, eos: no. It was additionally reported that the patient has been experiencing pain with stimulation in the neck region that started about 2-3 weeks ago. The pain became worse the last couple of days. The patient had used his magnet and disabled his device and pain went away. No trauma or manipulation to the device was reported. The patient's vns was programmed off. The patient's depression has been increasing since their vns has been programmed off. X-rays were received for review by manufacturer and their generator placement appeared normal and the filter feed-throughs appeared to be intact. The lead connector pin was verified to be fully inserted into the generator connector block. The lead was verified to be intact at the connector pin. Strain relief could not be assessed due to x-ray reviews provided, as views of the neck region were not sent for review. No acute angles or obvious gross lead discontinuities were observed in the visible portion of the lead. A portion of the lead, located behind the generator, could not be assessed. The patient is pending insurance approval to be scheduled for full revision surgery. No surgery date is set at this time.
