NHS Abdominal Aortic Aneurysm (AAA) Screening

An abdominal aortic aneurysm (AAA) is a bulge or swelling in the aorta, the main blood vessel that runs from the heart down through the abdomen. If untreated, it can grow and possibly burst, which can be life-threatening.

In the UK, AAA screening is offered to men aged 65 and over. Men are invited for screening during the year they turn 65. Men over 65 who have not been screened can request a test through their GP.

AAA screening is important because it helps to identify AAAs early on. Early detection can lead to timely monitoring or treatment, reducing the risk of the aneurysm bursting.

The screening test is a simple, painless ultrasound scan of the abdomen. It usually takes less than 10 minutes and provides immediate results.

There is no special preparation required for the AAA screening test. You can eat, drink, and take your medications as usual before the scan.

If an aneurysm is found, the treatment depends on its size. Small aneurysms are usually monitored with regular ultrasound scans, while larger aneurysms may require surgery.

AAA screening is a safe and simple procedure with very minimal risks. The ultrasound scan itself is entirely painless and without any known side effects.

Most AAAs do not cause any noticeable symptoms until they burst. However, some people might experience symptoms like a pulsating feeling in the abdomen, persistent back pain, or abdominal pain.

Routine AAA screening is not offered to women, as AAAs are less common in women. However, women with certain risk factors can discuss screening with their GP.

Men aged 65 and over, smokers, individuals with high blood pressure, and those with a family history of AAA are at higher risk of developing an abdominal aortic aneurysm.

The AAA ultrasound screening test is highly accurate in detecting aneurysms, particularly those that are large enough to require monitoring or intervention.

Most men only need to be screened once in their lifetime if no aneurysm is found. If an aneurysm is detected, the frequency of follow-up scans depends on its size.

Yes, AAA screening is offered free of charge by the NHS to eligible men aged 65 and over.

If you have a family history of AAA, it's advisable to discuss screening with your GP, especially if you are over the age of 65.

To reduce the risk of developing an AAA, you can maintain a healthy lifestyle: avoid smoking, manage blood pressure, eat a balanced diet, exercise regularly, and maintain a healthy weight.
