CRYOTHALAMECTOMY FOR PARKINSON'S DISEASE.
In a review of 61 patients with Parkinson's disease who were treated by cryothalamectomy, the technique of freezing a surgical target as compared with destroying it by alcohol or thermal heat was found effective and to a degree safer than other techniques. One patient died of unexpected cerebral hemorrhage. Of patients considered excellent candidates for the operation, 80 per cent had excellent and good results, while those considered good candidates showed 85 per cent excellent and good results. The results are more dependent on the selection of the patient as a candidate and the diffuseness of the pathophysiological circuits involved than on the technical factors of the cryogenic procedure.
