AAA screening is a simple ultrasound scan used to check for a swelling (aneurysm) in the abdominal aorta, the main blood vessel that carries blood from the heart through the abdomen. Detecting an aneurysm early allows it to be monitored or treated before it becomes dangerous.
Who is offered screening?
- In England, all men are routinely invited for AAA screening in the year they turn 65.
- Men aged 65 and over who have not previously been screened can contact their local AAA screening service to arrange an appointment.
- Screening is not routinely offered to women or men under 65 because the risk is lower in these groups.
What happens at the appointment?
- A small ultrasound probe is moved over the abdomen.
- The scan is painless, non-invasive, and usually takes less than 10 minutes.
Results
- Normal aorta: No further screening needed.
- Small aneurysm: Regular surveillance scans, usually every 12 months.
- Medium aneurysm: More frequent monitoring, usually every 3 months.
- Large aneurysm: Referral to a vascular specialist to discuss treatment options.
Why is it important?
- Most AAAs cause no symptoms. A large aneurysm can rupture, causing severe internal bleeding and a high risk of death. Screening helps identify aneurysms before this happens.
