Single-Center Complication Analysis Associated with Surgical Replacement of Implantable Pulse Generators in Deep Brain Stimulation.

Background/aims: Internal pulse generator (IPG) replacement is considered a relatively minor surgery but exposes the deep brain stimulation system to the risk of infectious and mechanical adverse events. We retrospectively reviewed complications associated with IPG replacement surgery in our center and reviewed the most relevant publications on the issue.

Methods: A retrospective analysis of all the IPG replacements performed in our center from January 2003 until March 2018 was performed.
