Abdominal Aortic Aneurysm (AAA) Screening
Abdominal aortic aneurysm (AAA) screenings detect dangerous swelling (aneurysm) of the aorta - this is the main blood vessel that runs from the heart and down through the abdomen to the rest of your body.
This type of swelling is more common in men aged over 65 than it is in women or younger men. This is why men are invited for screening in the year they turn 65.
More details about NHS Abdominal Aortic Aneurysm (AAA) screening programme can be found on the NHS Choices website.
