Surgical Occlusion of Anterior Choroidal Arteries in Parkinsonism

Abstract

An analysis of the treatment of parkinsonism by surgical occlusion of the anterior choroidal artery is presented with case documentation (6) and a review of the pertinent literature. The detailed pathologic examinations made of 4 hemispheres following anterior choroidal artery occlusion are presented. The distribution of the lesions, when present, varied both in location and extent within the globus pallidus. The failure to alleviate the symptoms of parkinson-ism and the attendant complication of paresis was disappointing. Variable circulatory factors and apparent "recircuiting" of the tremorgenic and rigidogenic neural impulses and/or their facilitatory impulses preserved the imbalance created by the disease process accounting for the failure.
