NHS Abdominal Aortic Aneurysm (AAA) Screening

What is an Abdominal Aortic Aneurysm (AAA)?

An abdominal aortic aneurysm (AAA) is a bulge or swelling in the main blood vessel (aorta) that runs from the heart down to the abdomen. If untreated, it can grow larger and potentially rupture, which can be life-threatening and result in severe internal bleeding. AAAs are more common in men and are particularly prevalent among individuals aged 65 and over.

The Importance of AAA Screening

AAA screening is crucial because most AAAs cause no symptoms and are often undetected until they rupture. Early detection through screening can help prevent rupture by allowing timely monitoring and treatment. The goal of the NHS AAA Screening Programme is to reduce deaths from ruptured AAAs through early diagnosis and intervention.

Who is Eligible for the Screening?

In the United Kingdom, the NHS offers AAA screening to men when they turn 65. Men over 65 who have not previously been screened can request a screening appointment through their GP. While the programme focuses on men, men and women with a family history of AAA or other risk factors may also discuss the need for screening with their healthcare provider.

What Does the Screening Involve?

The AAA screening is a simple, quick and painless ultrasound scan that measures the size of the aorta. The scan usually takes about 10 to 15 minutes, and the results are provided immediately. If an aneurysm is detected, its size determines the follow-up steps:

  • Small AAA (3.0-4.4cm): Yearly scans and lifestyle advice
  • Medium AAA (4.5-5.4cm): Scans every three months and lifestyle advice
  • Large AAA (5.5cm or larger): Referral to a vascular specialist for potential surgery

Conclusion

NHS AAA screening is a vital preventive service aimed at reducing the number of deaths caused by ruptured AAAs. By providing early detection and regular monitoring, the programme helps ensure that individuals at risk receive the care they need. If you are eligible, participating in AAA screening can significantly contribute to safeguarding your health and well-being.

Frequently Asked Questions

What is an abdominal aortic aneurysm (AAA)?

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.

Who is eligible for AAA screening?

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.

Why is AAA screening important?

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.

How is the AAA screening test performed?

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

Do I need to prepare for the AAA screening test?

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

What happens if an aneurysm is found?

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.

Are there any risks associated with AAA screening?

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.

What are the symptoms of an AAA?

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.

Can women be screened for AAA?

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.

Who is at higher risk for developing an AAA?

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.

How accurate is the AAA screening test?

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

How often should AAA screening be done?

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.

Is AAA screening free on the NHS?

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

Should I be screened for AAA if I have a family history of the condition?

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.

How can I reduce my risk of developing an AAA?

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.
