Unilateral pallidothalamic tractotomy for akinetic-rigid Parkinson's disease: a prospective open-label study.

Objective: Neurosurgical ablation is an effective treatment for medically refractory motor symptoms of Parkinson's disease (PD). A limited number of studies have reported the effect of ablation of the pallidothalamic tract for PD. In this study, the authors evaluated the safety and efficacy of unilateral pallidothalamic tractotomy for akinetic-rigid (AR)-PD.

Pallidothalamic Tractotomy for Parkinson Disease with 1-Year Follow-Up: A Case Report.

Background: The pallidothalamic tract connects the globus pallidus internus and the ventrolateral portion of the thalamus, and ablation of the pallidothalamic tract (pallidothalamic tractotomy [PTT]) reportedly exerts antiparkinsonian effects. However, the detailed clinical course has not yet been elucidated. Here, we present the first single case report of PTT performed in a patient with Parkinson disease, with 1-year follow-up.
