adult screening programme

Abdominal Aortic Aneurysm

An aneurysm occurs when part of an artery swells. It is caused by a damaged blood vessel or a weakness in the blood vessel wall. The pressure of blood in the artery causes it to 'balloon' out at the weak point. An aneurysm can rupture if not treated or monitored. This can lead to internal bleeding and death.

UK NSC screening recommendation Based on the last UK NSC review of this condition that occurred in August 2017.

Screening for this condition is recommended.

The UK NSC recommended that AAA screening could be offered to men aged 65 because:

  • the ultrasound scan used to find aneurysms is very reliable and it is very rare for a man who has had a normal result to develop a large aneurysm
  • once identified, AAAs can be monitored or treated, greatly reducing the chances of an aneurysm causing serious problems in the future

This was provided that:

  • the men invited were given clear information about the risks of surgery to repair an aneurysm
  • steps were taken to create networks of vascular surgical services

Evidence is that women should not currently be invited for screening as they are 6 times less likely than men to have an AAA and the risks of inviting them outweigh the benefits.
