Jul 14, 2022 · An embolization procedure blocks a specific blood vessel to stop abnormal bleeding. It uses substances (embolic agents) that include coils, foam and balloons.
Healthcare providers use endovascular coiling, a form of endovascular embolization, to block blood flow into an aneurysm. An aneurysm is a weakened area in the wall of an artery. If an aneurysm ruptures, it can cause life-threatening bleeding and brain damage. Preventing blood flow into an aneurysm helps to keep it from rupturing.
Embolization is a minimally-invasive procedure that stops blood flow in target areas. It is done while preserving normal blood flow in the surrounding regions to keep your tissues healthy while dealing with problematic bleeding.
Endovascular therapy is a minimally invasive way to diagnose and treat a patient from within a blood vessel. In the case of a brain aneurysm, this treatment is called coil embolization, or "coiling." Coiling does not require open surgery.
(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 aneurysms in the brain. It can also be used for other medical conditions when open surgery might be risky.
However, many patients receive brain imaging for other reasons, and unruptured aneurysms are discovered. If the anatomy is suitable and if it is felt that the aneurysm does pose a risk for future rupture, the aneurysm can be treated with coil Embolization.
