Abdominal Aortic Aneurysm or AAA (triple A) is a weakening of the aortic wall causing a bulging or pouch that is greater than 50% of the normal width. This condition becomes life threatening when the weakened area gives way under the constant pressure from blood flow. If an aneurysm ruptures or bursts this may lead to a life threatening hemorrhage. Early detection can lead to life saving interventions to prevent aneurysm rupture.
