Often Silent, a True Medical Emergency
An aneurysm occurs when the walls of an artery become weak and bulge outward. most aneurysms are found during an exam for another, unrelated problem. In their early stages, most do not cause symptoms. As an aneurysm progresses, symptoms may appear, but may be mistaken for other health problems.
Aneurysms can grow larger over time, so it is important to monitor them carefully. The greatest risk is that the aneurysm will rupture (burst) or dissect (split). These are true medical emergencies. Call 9-1-1 immediately!
