Chemoembolization. Definition

Medical Definition: Chemoembolization

Procedure for injecting chemotherapy drugs directly into the circulatory system that feeds the liver, blocking the blood supply to the tumor by surgery or mechanical, and anticancer drugs are administered directly into tumor. This allows a higher concentration of the drug is in contact with the tumor for a longer period .. When injecting drugs directly into the blood vessels supplying the tumor, the drug concentration is between 20 and 200 times higher than standard chemotherapy. Then the doctor makes an embolization, the medical term that designates a lock on the portion of the artery leading to the tumor. This block closes the blood flow to the tumor and allows blood to flow into the rest of the liver.
