What is Intra-arterial chemotherapy?
The arteries that supply blood to the brain, and to a brain tumor, carry oxygenated blood from the heart and lungs. Although all drugs are, in fact, delivered to the brain by the arteries, intra-arterial chemotherapy (IAC) involves the placement of a catheter directly into the artery feeding the tumor. This provides a higher concentration of the drug closer to the tumor.
