Meeting: 2016 International Congress

Abstract Number: 124

Keywords: Deep brain stimulation (DBS), Implanted pulse generators(IPG)

Session Information

Date: Monday, June 20, 2016

Session Title: Surgical therapy: Other movement disorders

Session Time: 12:30pm-2:00pm

Location: Exhibit Hall located in Hall B, Level 2

Objective: To investigate the incidence of adverse events and postoperative infections of IPG replacements in a multicenter cohort.

Background: Deep brain stimulation (DBS) is a growing treatment modality and most DBS systems require replacement of the implantable pulse generator (IPG) every few years. The literature is rather scarce regarding the potential impact of the adverse events of IPG replacements on the longevity of DBS treatments.

Methods: Medical records of 808 patients from one Australian and five Swedish DBS centers with a total of 1293 IPG replacements were audited. A logistic regression model was used to ascertain the influence of possible predictors on the incidence of adverse events.

Results: The overall incidence of major infections was 2.3% per procedure, 3.7% per patient and 1.7% per replaced IPG. 93.3% of these patients needed partial or complete removal. DBS removal became permanent in 7 cases. There were statistical significant increased risk of infection for males (OR 3.6, p= 0.026) and for each previous IPG replacement (OR 1.6, p< 0.005).

Conclusions: The risk of postoperative infections of IPG replacements in DBS increase with each previous procedure and there is need to develop strategies to reduce the frequency of IPG replacements.
