Endovascular embolization is becoming a standard
treatment option for people who have a brainaneurysm. It may be used for people who are at high
risk for complications from a surgical repair (clipping) of the aneurysm.
Endovascular embolization involves packing the aneurysm with a substance (for example, soft coil or mesh) that fills the stretched and bulging section of the blood vessel.
This helps seal off the aneurysm and reduces the risk of the aneurysm leaking
blood or rupturing. The doctor uses X-rays to identify the aneurysm and to
put the substance in the aneurysm.
success of this treatment depends on the size and location of the aneurysm, the
skill of the doctor, and the person's general health. Complications include a leak or rupture of the aneurysm or bleeding caused by the movement of the medical instruments through the blood vessels.
Studies are being done to determine the long-term success of this
treatment and how to prevent complications. In cases where endovascular
embolization is not possible, aneurysm clipping with craniotomy is done.
