Abstract: The authors present results in 40 patients with tremor, in whom electrodes (uni and bilateral) for DBS were implanted in the ventral intermediate nucleus (VIM) of the thalamus.
Methods: Forty patients with disabling tremor, with drug-resistant spite of optimum therapeutic trials with poor response were referred to do surgery. 30 patients had bilateral essential tremor. These patients were implanted with electrodes for DBS Activa (Medtronic). Ten patients had unilateral parkinsonian tremor and they received unilateral implantation of model (Activa SC DBS)
Results: All four patients showed relieve of the tremor symptoms with significant tremor control seen at the scores. There were no definite adverse events after the electrodes implants for DBS, the only ones were all transient and promptly reversed after the adjustment of the parameters.
Conclusions: The results the authors found in this study indicate that VIM-Stimulation is effective for tremor control either parkinsonian or essential tremor. It has the advantage of be bilateral with less risk than VIM ablations. The results correlate with the data in the literature.
