Computed Tomography Guided Stereotactic Thalamotomy Using the Brown-Roberts-Wells System for Nonparkinsonian Movement Disorders

Abstract

A technique is described for stereotactic thalamotomy, using the Brown-Roberts-Wells (BRW) system and computed tomography (CT) without the need for ventriculography. Previous reports have suggested that the BRW system lacks sufficient accuracy (compared with ventriculography) for CT-directed functional neurosurgery. However, using this method, our findings demonstrate excellent clinical accuracy and safety in 12 consecutive patients with nonparkinsonian movement disorders.
