What do I need to know about embolization?

Embolization is a procedure to create a clot, or block, in a blood vessel. This stops blood from flowing to the area. The procedure may be used to treat many conditions. It can help stop heavy bleeding (hemorrhage), or prevent an aneurysm from rupturing. An abnormal connection between arteries can be removed. Embolization can stop blood flow to a tumor, such as a uterine fibroid or a cancer tumor. Chemotherapy medicine may be given during an embolization to treat a cancer tumor. This is called chemoembolization.

How do I prepare for the procedure?

Embolization is sometimes done as an emergency procedure. This means you will not have time to prepare. For an embolization that is not an emergency, the following are general guidelines for how to prepare:

What are the risks of embolization?

You may bleed more than expected or develop an infection. The area being treated may be damaged during the procedure. Your artery may be damaged from the catheter, or you may develop a blood clot. Your kidneys may be damaged from the contrast liquid. The material being put into the artery may go to the wrong place. This can stop blood flow to healthy tissue. The procedure may not work, or it may not relieve your symptoms.
