When an aneurysm bursts, it releases blood into the space between the brain and skull, irritating the brain’s lining and damaging brain cells. The brain is also deprived of oxygen-rich blood, resulting in a stroke.
Emergency surgical treatment for a rupture aneurysm may require microsurgical clipping, where a small clip is placed across the neck of an aneurysm to block normal blood flow. Another option is endovascular coiling, a catheter-based treatment that prevents blood flow into the aneurysm.
When an artery is large, inaccessible or it is too damaged, bypass surgery may be needed. During the procedure, clips are used to completely block the artery and aneurysm while blood flow is rerouted around the blocked artery and into a nearby artery so blood can flow freely.
