ObjectiveThe use of Deep Brain Stimulation (DBS) has been increasing. It follows the premise of neuromodulation in that it is reversible, as compared to previous lesioning procedures.Materials And MethodsComplications with DBS are inherently low and range from short-term complications during surgery such as hemorrhage to long-term complications that include lead fractures and infection. Over time, the authors have experienced indications for additional lead placements or change in position of the lead on the ipsilateral side. There is the inherent possibility of direct contact between leads or the microelectrode. This can lead to malpositioning, displacement of a lead placed previously, and malfunctioning.ResultWe report a case in which a lead placed previously becomes displaced during microelectrode recording on the ipsilateral side.ConclusionThis scenario was corrected and had no clinical or functional complication. Placement of an additional ipsilateral DBS lead can be a safe and effective treatment option.© 2012 International Neuromodulation Society.
