Abstract
OBJECTIVE: To analyse the occurrence of hardware-related complications in patients with deep brain stimulation (DBS), over a long period of time. METHOD: All patients operated on with DBS at our institution between 1993 and 2002 were followed with respect to adverse events related to the implanted hardware. RESULTS: One hundred and nineteen consecutive patients underwent 139 procedures with implantation of 161 electrodes. The minimum follow-up was 12 months. The follow-up time was 540 electrode-years. The rate of hardware-related complications per electrode-year was 4.3%. In total, 17 patients (15%) had 23 hardware-related complications. These included 8 electrode breakages, 4 electrode migrations, 2 stimulator migrations, 3 erosions, 2 erosions and infections, 2 infections and 2 cases of stimulator malfunction. The majority of these complications occurred during the first four years in our experience. CONCLUSIONS: DBS is a life-long therapy that requires a life-long follow-up. Increased experience and adaptation of surgical technique are the main determinants for avoidance of hardware-related complications.
