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.
