Liver-directed Therapies (embolization techniques)

A variety of therapies, all intended to achieve a similar end result, exist in this category. They include arterial embolization, chemoembolization and radioembolization. Each type of embolization uses a specific technique to block or reduce the flow of blood through the hepatic artery to the liver.

The hepatic artery is the main blood vessel that transports blood to the liver, so blocking it prevents the cancer cells from getting nutrients that they require to grow. These techniques are also used to deliver chemotherapy or radiation directly to the tumour site, and are often preferred for patients with liver metastases who are not candidates for surgery.
