Aneurysm (Brain) (cont.)

What is the survival rate and prognosis for a brain aneurysm?

Researchers estimate that about 6 million people in United States have an unruptured brain aneurysm, and about 10% to 15% of these people will have more than one brain aneurysm. Someone with an unruptured brain aneurysm has about a 1% chance of the aneurysm rupturing per year. Patients with “giant” aneurysms (1 inch or greater in diameter) have a much higher risk of rupture. The survival rate for those with a ruptured brain aneurysm is about 60% (40% die). For those who survive and recover, about 66% have some permanent neurological defect. In summary, patients with small brain aneurysms that do not rupture (about 80%) have a very good prognosis while those who suffer a rupture have a fair to poor prognosis.
