What is a Tumor Embolization?
Embolization is a form of palliative (non-curative) treatment for cancer. This includes tumors originating in one area of the body or those that have spread (metastasized) to other areas of the body. The artery to the tumor is blocked off (embolized) with small particles to starve the tumor of oxygen and nutrients.
In certain circumstances, chemotherapy drugs are administered at the time of embolization or mixed with the particles to block the artery (chemoembolization). This allows a higher concentration of chemotherapy (compared with systemic chemotherapy) to be administered where it remains for up to one month within the tumor.
Following the embolization, you may experience significant abdominal pain that may start during the latter part of the procedure and usually lasts 2 or 3 days. This may also be associated with fever, nausea and vomiting, which is known as “post-embolization syndrome.” You will receive a script to control the pain and nausea, which can last up to 5 days depending upon the severity and duration of the post embolization syndrome.
During the procedure, you will lie flat on the examination table and IV sedation will be given through an IV to make you comfortable. A small catheter (tube) is inserted into the artery in either the right or left groin and guided to the part of the body to be treated or examined.
Once the catheter is placed, contrast (IV) dye is injected and images of the arteries are obtained. Small metal coils, plastic beads, or sponge like material (gelfoam) are deposited into the blood vessel through the catheter to stop the flow of blood.
The average length of the procedure is between 1-2 hours. At the completion of the examination, the catheter is removed and pressure is applied over the groin for 10-15 minutes to prevent bleeding. You will need to remain flat in bed for 4-6 hours following the procedure to prevent bleeding from the groin.
How do I prepare for the procedure?
No solid food after midnight the day before your procedure. Clear liquids are allowed the morning of the procedure unless told otherwise. This includes: water, tea, broth, popsicles, coffee without cream, 7-up, sprite, apple juice, or white cranberry juice.
