[Stereotaxic surgery in Parkinson's disease. A preliminary report of 2 cases]

Two patients presenting Parkinson's disease underwent thalamotomy by a stereotactic procedure at San Fernando Clinic. These patients were selected using a strict protocol. The surgical procedures and the results have been described. Review of potential complications are also discussed. Thalamotomy by stereotactic surgery is a method that offer excellent results in patients presenting movement disorders. Specifically in Parkinson's disease, it has demonstrated a great effectiveness in abolishing tremor and in controlling hypertonia. Bradykinesia does not seem to respond to this procedure.
