Abstract
Since 1992 there has been renewed interest in pallidotomy now that the limitations and adverse effects of long-term dopaminergic therapy have become more apparent and more difficult to control in patients with advanced Parkinson’s disease.
The authors describe the effect of pallidotomy in 19 patients, sixteen of whom had advanced Parkinson’s disease with painful dystonia and/or response fluctuations with severe akinesia while in “off” and dyskinesias while in “on”. One patient had cortico-basal degeneration with rigidity, one patient had secondary dystonia and one had dystonic posturing due to Wilson’s disease. Fifteen patients underwent unilateral pallidotomy; four patients had a staged bilateral procedure.
Follow-up ranged from 3 to 42 months (mean 18 months). All patients with peak-dose dyskinesias and/or dystonia had marked reduction of symptoms, including the cases of Wilson’s disease and secondary dystonia. The akinesia and rigidity scores of Parkinson-patients in “off” were greatly reduced, mainly but not only on the contralateral side. Evaluation by the patients showed remarkable improvement of symptoms in 79%, leading to substantially improved functional abilities in 68%.
In this series the decrease in dopamine-response fluctuations, dystonia, hypokinesia and rigidity with functional improvement as judged by examiners and patients reflect a significant regain of independence.
