The capillaries of the cerebral endothelium possesses a unique Blood Brain Barrier (BBB) property due to a continuous basement membrane, tight endothelium and lack of pinocytosis. This specialized barrier prevents passage of systemic chemotherapy into the brain tumor. To obtain an effective concentration of the chemotherapeutic agent, a transient reversible disruption of the barrier is required which is achieved by intra-arterial methotrexate and intravenous cytoxan infusion. The degree of disruption of the barrier was monitored by means of radio-isotope brain scan. The neuroradiologic special procedure and its role in the management of advanced brain tumor by modification of the BBB is presented.
