Multiple Choice

Yttrium-90 radioembolization is used in which scenario?

Yttrium-90 radioembolization is a form of targeted internal radiation therapy used for hepatocellular carcinoma that cannot be removed by surgery. It exploits the fact that liver tumors, including HCC, draw most of their blood supply from the hepatic artery, so microspheres carrying beta radiation can be delivered directly to the tumor while sparing most normal liver tissue supplied by the portal vein. This approach is particularly helpful when the disease is unresectable or when portal vein thrombosis is present, because it avoids relying on arterial embolization that could compromise liver function. It can also be used after TACE when further embolization or chemotherapy is not feasible or has failed. It is not indicated for resectable tumors with clear margins, benign liver lesions, or acute liver failure requiring transplantation.
