Abdominal Aortic Aneurysm

Definition/Description

Large aneurysms are rare. If a large aneurysm bursts, it causes internal bleeding and is usually fatal.

AAAs are most common in men aged over 65. A rupture accounts for more than 1 in 50 of all deaths in this group and a total of 6,000 deaths in England and Wales each year.

Referral Criteria/Information

Men aged 65 (in the year of their 65th birthday) are offered screening by the National AAA Screening Programme

Referral

1) Screening Tests

All men are invited for a screening test in the year that they turn 65 by NAAASP. The test involves an ultrasound scan which takes around 10-15 minutes.  The men are advised verbally of their result at this point.  If the result is less than 3cm (non-aneurysmal) the man is discharged from the screening programme and will not be sent a further appointment.  The GP will be notified of the result by letter

If an aneurysm is found over 3 cm, surveillance is offered either yearly or quarterly depending on size.  Any referral required will be from NAASP to the appropriate Service and the GP will be informed through electronic letter

Men who are over 65 and believe they have not been invited previously can contact their Local AAA screening service for advice Contact Telephone Number: 01482 675507.

Further information on the screening is available in the information for health professionals and patient leaflet AAA screening: information for health professionals - GOV.UK (www.gov.uk)  Abdominal aortic aneurysm screening: invitation leaflet - GOV.UK (www.gov.uk)

Occasionally aneurysms are found incidentally through scans for other conditions.  In these cases if a man over 65 years of age, please contact NAAASP in the first instance to discuss if the man is under NAAASP surveillance and for further information or referral guidance.

2) GP Referral - Routine

Unless emergent, i.e. Symptomatic AAA, referral from other services should be through the GP.

Women and men under 65 are not invited for screening by NAAASP. However high risk patients can be referred to the vascular department, such as men over 60 who have a family history of aneurysms
