Endovascular Embolization is a minimally invasive technique performed to cut off the blood supply to a specific part of an artery. The goal of the treatment is to prevent bleeding in the problem area and to reduce the risk that the blood vessel will break open (rupture).
This procedure may be used to treat:
- Arteriovenous malformation (AVM)
- Brain aneurysm
- Carotid artery cavernous fistula (a problem with the large artery in the neck)
- Certain tumors
You may have general anesthesia and a breathing tube. Or, you may be given medication to relax you, but not enough to put you to sleep.
- A small surgical needle hole will be made in the groin area. The health care provider will use a needle to create a hole in the femoral artery, a large blood vessel.
- A tiny, flexible tube called a catheter is passed through the open skin and into the artery.Dye is injected through this tube so that the blood vessel can be seen on x-ray images.
- The health care provider gently moves the catheter through the blood vessel up to the area being studied.
- Once the catheter is in place, the health care provider places small plastic particles, glue, metal coils, foam, or a balloon through it to seal off the bad blood vessel. (If coils are used, it is called coil embolization.)
