Risk of rupture in small brain aneurysms is low, study finds
More patients undergoing brain-imaging scans are being diagnosed with small aneurysms, or enlargements of an artery, when tested for symptoms like severe headaches. These aneurysms can grow and rupture, causing significant disability and death. These aneurysms are often treated as soon as they are discovered to prevent these bad outcomes. However, a Yale researcher has found that the risk of small aneurysm rupturing may actually be quite low.
