Endovascular coil embolization is becoming a standard
treatment option for people with a brain
aneurysm. It may be used for people who are at high
risk for complications from a surgical repair of the aneurysm.
Endovascular coil embolization involves packing the aneurysm with a soft
platinum coil that fills the stretched and bulging section of 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
guide the coil through the blood vessel to 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
bleeding from the aneurysm or movement of the coils in the blood vessel.
Studies are being done to determine the long-term success of this
treatment and how to prevent complications. In cases where endovascular coil
embolization is not possible, aneurysm clipping with craniotomy is done.
