Intracranial Intra-arterial Infusions
In this treatment, select patients with brain tumors are now having chemotherapeutic agents injected directly into the arteries feeding the tumor. Superselective Intra-arterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. This technique threads a tiny catheter through the patient's femoral artery in the leg, up through the body and neck and into the brain. Once the catheter reaches the brain, chemotherapy is released to the blood vessels that feed the tumor.
