A stereotactic technique for volumetric interstitial implantation in the brain.

Stereotaxis, a method of localizing a specific point using three dimensional coordinates, has greatly improved since the advent of computed tomography (CT). A simple, noninvasive stereotactic system which enables rapid, parallel placement of multiple interstitial catheters for treatment of malignant brain tumors has been developed. Departing from traditional stereotactic methods, the implantation procedure is performed in one stage--entirely in the CT suite. Perioperative nursing responsibilities include mastering the technical aspect of a high precision system as well as meeting the special needs of the patient undergoing this procedure. Initially developed for use in volumetric interstitial brachytherapy, the procedure is now being used in Phase II clinical trials of volumetric interstitial hyperthermia in the management of patients with intracranial malignancies.
