It was reported the patient went to the hospital because she felt her symptoms worsening.Upon evaluation of the patient's dbs system by the neurologist, the impedance measured high on the system.Consequently, surgical intervention was taken, during the procedure the neurosurgeon disconnected the extensions from the implantable pulse generator (ipg), after the extension was checked it showed high impedance on all contacts.The neurosurgeon disconnected the lead from the extension and measured the impedance of the lead.Multiple lead contacts showed high impedance, but the patient could be stimulated through the contacts.Based on the current going through the contacts the neurosurgeon decided to replace the lead extension with a new one, and the issue was addressed.
