The objective of this investigation was to present the operative and hardware complications encountered during follow-up of patients with in situ deep brain stimulators. The study took the form of a retrospective chart review on a series of consecutive patients who were treated successfully with insertion of deep brain stimulators at a single centre by a single surgeon between 1999 and 2005. During the study period, a total of 60 patients underwent 96 procedures for implantation of unilateral or bilateral DBS electrodes. The mean follow-up period was 43.7 months ( range 6 - 78 months) from the time of the first procedure. No patients were lost to follow-up or died. Eighteen patients (30%) developed 28 adverse events, requiring 28 electrodes to be replaced. Seven patients developed two adverse events and two patients developed three adverse events. The rate of adverse events per electrode-year was 8%. We observed a higher proportion of early complications ( 56 months postoperatively) in patients with Parkinson's disease, while dystonic patients had more late complications ( 46 months postoperatively) and no early complications. Thirty per cent of our patients developed an adverse event that could potentially lead to revision of the implanted hardware. In patients with Parkinson's disease most of the complications tend to occur during the first 6 months postoperatively, while in dystonic patients most occur between 12 and 24 months postoperatively.
