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.
This procedure cuts off the blood supply to a certain part of the body.
Treatment – endovascular embolism; Coil embolization; Cerebral aneurysm – endovascular; Coiling – endovascular; Saccular aneurysm – endovascular; Berry aneurysm – endovascular repair; Fusiform aneurysm repair – endovascular; Aneurysm repair – endovascular
You may have
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.)
This procedure can take several hours.
Why the Procedure Is Performed
The procedure is most often used to treat
Not all aneurysms need to be treated right away. Those that are very small (less than 3 mm) are less likely to break open.
Your doctor will help you decide whether it is safer to have surgery to block off the aneurysm before it can rupture.
This procedure may be used to treat:
- Brain aneurysm
- Carotid artery cavernous fistula (a problem with the large artery in the neck)
- Certain tumors
- Bleeding at the site of the needle puncture
- Bleeding in the brain
- Damage to the artery where the needle is inserted
- Dislodged coil or balloon
- Failure to completely treat the abnormal blood vessel
- Symptoms that keep returning
Before the Procedure
This procedure is often performed on an emergency basis. If it is not an emergency:
- Tell your doctor or nurse what drugs or herbs you are taking and if you have been drinking a lot of alcohol.
- Ask your doctor which medicines you should still take on the day of the surgery.
- Try to stop smoking.
- You will usually be asked not to eat or drink anything for 8 hours before the surgery.
- Take the medicines your doctor told you to take with a small sip of water.
- Arrive at the hospital on time.
After the Procedure
If there was no bleeding before the procedure, you may need to stay in the hospital for 1 – 2 days.
If bleeding occurred, your hospital stay will be longer.
How fast you recover depends on your overall health, the severity of your medical condition, and other factors.
In most cases, endovascular embolization is a successful procedure with good outcomes.
The outlook also depends on any brain damage that occurred from bleeding before, during, or after the surgery.
