A study comparing pneumoencephalography and ventriculography in patients undergoing basal ganglia surgery is presented. In each series 100 cases were used and compared as to target localization, tolerance of the patient to the air study and postoperative complications. It was found that ventriculography was better tolerated by the patient and that the patient had fewer postoperative problems, i.e., headache, nausea, vomiting and mental confusion. Ventriculography also gave better visualization of intracerebral landmarks and was considered preferable to pneumoencephalography in the localization of the cerebral target prior to cryothalamectomy.
