You look at the size of the aneurysm, if there’s a big one you’re concerned about it maybe rupturing over time, you’re worried about the shape, if there’s a lot of irregularity on the dome that means there’s a lot of pressure inside. Carolyn Brockington More Quotes by Carolyn Brockington More Quotes From Carolyn Brockington Think of [the aneurysm] like a balloon coming off the wall of the artery. On the neck of the balloon they put a small clip in so blood can’t go into the aneurysm, which means the balloon will deflate, the more newer approach is an endovascular approach using an angiogram. They go into the balloon itself and fill the balloon with small coil so blood can’t go into the balloon, and therefore the aneurysm deflates. Carolyn Brockington health
