--------- Forwarded message ---------- From: E-MOVE <[log in to unmask]> To: E-MOVE <[log in to unmask]> Date: Thu, 31 Oct 2002 19:22:29 GMT Subject: Long-Term Hardware Complications of Deep Brain Stimulation Message-ID: <B0000028297@liquidus-www> Long-term hardware-related complications of deep brain stimulation MY Oh, A Abosch, SH Kim, AE Lang, AM Lozano Neurosurgery, 2002;50:1268-1276 Hardware-related complications occurred in one quarter of patients with implanted DBS electrodes in this long-term follow-up study. A retrospective chart review was conducted for 84 consecutive patients (53 PD, 9 ET, 12 other diagnoses) treated at a single center by a single surgeon over 6 years. Four patients did not receive implanted electrodes due to lack of benefit during trial stimulation, and one did not due to intraoperative hemorrhage. In the remaining 79 patients, 124 electrodes were implanted. Minimum follow-up was 12 months, and the mean follow-up was 33 months. Twenty patients had 26 hardware-related complications, involving 23 electrodes. There were 4 lead fractures, 4 lead migrations, 3 short- or open circuits, 12 erosions and/or infections, 2 foreign-body reactions, and 1 CSF leak. Twenty-nine additional procedures were required to address these complications. The authors note, “Unlike lesioning procedures, in which complications would be evident early in the operation, the potential for hardware-related complications of DBS continue as long as the system remains implanted. In our study, the mean time to complication was 10 months, which suggests that the majority of DBS-related lesions would have been missed had we ended our patient follow-up at 6 months.” =======================================================================C opyright 2002 WE MOVE Editor: Richard Robinson ([log in to unmask]) - Your E-MOVE news subscription is provided free of charge, courtesy of WE MOVE.
