Hardware infection incidence for DBS implantations performed in a diagnostic MR suite is reported. A total of 164 DBS procedures were performed in movement disorder patients resulting in six (3.7%) hardware related infections. Two infections occurred within the first 10 cases and led to a change in sterile practice. Over the last 154 cases four (2.6%) infections have been reported and all were associated with implantation of the IPG controller, which is done in a separate surgical procedure 1-3 weeks after DBS implantation. Infection risk when implanting DBS electrodes in a diagnostic MR suite is comparable to conventional OR procedures.
