An Abdominal Aortic Aneurysm (AAA), a specific kind of aneurysm, is a condition in which the lining of the blood vessel called the aorta is enlarged within the abdomen. Abdominal aortic aneurysms pose a threat because they are usually silent until a medical emergency occurs.
The abdominal aorta is the largest blood vessel in the body and the main artery that originates in the heart. As the lining weakens from age and other risk factors, the vessel wall thins and expands. The most common location for an AAA is between where the aorta divides to supply blood to the kidneys and where it divides to supply blood to the pelvis and legs.
Screening for Aortic Aneurysms – A painless, non-invasive procedure, an abdominal aortic aneurysm screening requires you to lie on your back while a technician uses ultrasound to take images and measurements of your abdominal aorta.
