View in Spanish: Infusión de un miembro aislado

Isolated limb infusion (I-soh-LAY-ted LIM in-FYOO-zhun)
A procedure used to deliver anticancer drugs directly to an arm or leg but not to the rest of the body. The flow of blood to and from the limb is temporarily stopped with a tourniquet (a tight band around the limb). Catheters (small, flexible tubes) attached to a pump are put into an artery and a vein in the limb so that blood can be circulated through the pump into the limb. Anticancer drugs are injected into the catheters. Wrapping the limb in a heated blanket or warming the drugs or blood may help the drugs work better.
