The following images were provided to the Chelsea King Burney Charity by a Brain Aneurysm Survivor. This is what an aneurysm looks like after the Coiling Treatment. 

Technology allows surgeons to treat brain aneurysms with Endovascular Treatment. 

In this type of treatment, a small skin incision is made and a catheter is guided by an X-ray through the patients artery (usually in the groin) and into the aneurysm.  Coiling is one of the treatments for aneurysms and is often a prelude to surgery in brain AVM's. 

During coiling the aneurysm is filled with a soft, platinum wire which is delivered by the catheter. The coil as well as the clotting will prevent the blood flow into the aneurysm. Sometimes due to the size and shape of the aneurysm flow diverters may be necessary. Flow Diversion is often used with coiling. This is where a stent is placed in the blood vessel of the aneurysm and will divert the blood flow away from the aneurysm. This helps the blood vessel to restructure itself and prevent the aneurysm from growing. It also helps secure the coils in place while the blood clots, helping to prevent a rupture. Flow diversion​ is a method that doesn't require entering the aneurysm which can be risky. 

 

Sometimes it is necessary for the surgeon to create a bypass to reroute blood flow around the aneurysm so that it can be safely closed.  This also ensures that the blood continues to flow to the part of the brain that needs it.   The surgeon then inserts tiny coils into the diseased vessel until it is completely closed.  The coils remain there permanently.
