Abdominal aortic aneurysm (AAA) screening is a way of checking if there’s a bulge or swelling in the aorta, the main blood vessel that runs from your heart down through your tummy.

This bulge or swelling is called an abdominal aortic aneurysm, or AAA.

It can be serious if it’s not spotted early on because it could get bigger and eventually burst (rupture).
