Abstract

BACKGROUND: Some patients with deep brain stimulation (DBS), where removal of implants is indicated due to hardware related infections, are not candidates for later re-implantation. In these patients a rescue lesion through the DBS electrode has been suggested as an option. In this case report we present a patient where a pallidotomy was performed using the DBS electrode. CASE DESCRIPTION: An elderly woman with bilateral Gpi DBS suffered an infection around the left burr hole involving the DBS electrode. A unilateral lesion was performed through the DBS electrode before it was removed. No side effects were encountered. Burke-Fahn-Marsden (BFM) dystonia movement scale score was 39 before DBS. With DBS before lesioning BFM score was 2.5 points. The replacement of the left sided stimulation with a pallidotomy resulted in only a minor deterioration of the score to 5 points. CONCLUSIONS: In the case presented here a small pallidotomy performed with the DBS electrode provided a satisfactory effect on the patient's dystonic symptoms. Thus, rescue lesions through the DBS electrodes, although off-label, might be considered in patients with Gpi DBS for dystonia when indicated.
