[Stereotaxy for parkinsonian tremor].
Thalamotomy with microelectrode recording is effective for the suppression of drug resistant tremor in patients with Parkinson's disease. In our series, thalamotomy was effective in 26 of 28 patients(93%). In one case of tremor recurrence, thalamic stimulation was effective for tremor control. Complications of thalamotomy were contralateral weakness in one case and subcortical hemorrhage in another case. Flexibility of thalamic stimulation and stimulation of the subthalamic nucleus(STN) for tremor control and complication avoidance makes them superior to thalamotomy. Surgical option is chosen between thalamotomy or/and thalamic stimulation, and bilateral thalamic or STN stimulation for symptoms, severity, and the patient's condition.
