PURPOSE Stereotactic pallidotomy, which has evolved as a result of technological
advances in high-resolution MR imaging and microelectrode electrophysiological recording …

Determination of acute pallidotomy-produced lesion volumes, pre-and postpallidotomy
globus pallidus (GP) volumes, and assessment of lesion shape using magnetic resonance …

From October 1992 through December 1996, we performed 109 ventroposterolateral
pallidotomies on 104 patients with Parkinson''s disease. Throughout the series, we have …

✓ The authors report the postoperative magnetic resonance (MR) imaging findings in 36
patients with advanced Parkinson's disease who underwent unilateral microelectrode …

Object. Pallidotomy for the treatment of medically refractory Parkinson's disease (PD) has
enjoyed renewed popularity. However, the optimal surgical technique, lesion location, and …

Summary¶ Objectives. A quantitative on-line analysis of electrical activity in the pallidum of
Parkinsonian patients has been developed to determine the focal point of lesioning …

OBJECTIVE: To assess the position of radiofrequency pallidotomy lesions placed using
microelectrode stimulation and cellular recordings in relation to a stereotactically defined …

Objective: To study the effects of unilateral stereotactic pallidotomy performed without
microelectrode recording for advanced Parkinson's disease. Methods: Stereotactic …

✓ Pallidotomy has become a widely used treatment for medically refractory Parkinson's
disease. However, the optimal lesion size and location within the pallidum have not yet been …

We have studied the effects of unilateral ventral medial pallidotomy in 26 patients with
medically intractable Parkinson's disease with marked drug-induced dyskinesias …
