Endovascular embolization
Definition
Endovascular embolization is a medical procedure to treat abnormal blood vessels in the brain and other parts of the body. It is an alternative to open surgery.
Alternative Names
Treatment - endovascular embolism; Coil embolization
Description
A small surgical cut 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. Next, a tiny, flexible tube called a catheter is passed through the open skin and into the artery. Dye may flow through this tube so that the artery may be seen on medical images.
While looking at live medical images of the area, 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 sends small plastic particles, glue, metal coils, foam, or a balloon through it to seal off the bad blood vessel. The sealing material used depends on your individual condition. (If coils are used, it is called coil embolization.) More than one type of material may be used.
Risks
- Bleeding
- Bleeding in the brain
- Failure to completely treat the lesion
