Event Description

It was reported to manufacturer that the treating vns physician saw the vns pt due to swelling in the left armpit and possible generator migration. X-rays were sent to manufacturer to review, and the migration event could not be confirmed as there were no baseline x-rays to compare them to. Diagnostic tests were performed following the onset of the reported event and revealed normal device function. Approximately a week later, the swelling appeared to be improving. Further info received revealed that the treating physician saw the pt again at a later date due to the continuation of the migration of the generator, which the pt believed was causing painful stimulation. Additionally, it was reported that the pt was experiencing an increase in seizure activity. The physician discussed with the pt, the possibility of surgical intervention. The pt then reported that she was seen by the primary care physician and stated that an infection was present, and that the swelling has gotten worse had moved down the left arm.

The fever had resolved, and the swelling was improving. The vns device was disabled and they are continuing to monitor the pt. Good faith attempts to obtain additional info have been made, but have been unsuccessful to date.
