Angiographies and Embolization

Trans Arterial Chemoembolization, Radioembolization and Bland Embolization

What is a trans-arterial chemo and radioembolization?

This procedure is usually a palliative treatment for certain types of liver tumors and metastatic disease. It is extremely effective in treating primary liver malignancies and certain types of metastatic disease when combined with other therapies.

How do these procedures work?

Both of these therapies work by delivering medication to the tumor directly through its arterial blood supply.

In chemoembolization, chemotherapy drugs are attached to tiny beads and delivered locally to the tumor.

Radioembolization is similar to chemoembolization but radiotherapy materials are attached to the beads and then delivered locally to the tumor.

These therapies also block blood supply to the tumor, thus depriving the tumor nutrients and oxygen that it requires for growth. Since these drugs are delivered locally there are fewer systemic side effects.

What kind of tumors respond to these therapies?

These therapies are most commonly used to treat primary and metastatic liver cancers. They are used preoperatively to decrease blood loss during surgery and most commonly used in preoperative surgeries of certain types of metastatic lesions to bone, kidneys and pelvic tumors.

What kind of anesthesia is used?

These procedures are usually done under local anesthesia. Certain types of intravenous anesthesia is also used which decreases pain during procedure. General anesthesia is rarely used.

What are the side effects and risks?

The most common side effects are pain, fever and nausea. These usually last for a couple of days but are easily controlled by medications.
