AAA Screening

AAA Screening

One ultrasound, once, for men in the year they turn 65. Ten minutes for a condition that is otherwise silent until it kills.

Men in the year they turn 65, and self-referral for men over 65

Once — a single scan

England, Scotland, Wales and Northern Ireland

NHS screening is free — this page explains it, we do not sell it

Honest about who benefits and who may be harmed

Talk it through with a GP

Screening itself is free on the NHS. If you want a result explained, have been recalled, or missed an invitation and are not sure what to do, a 20-minute appointment with a GMC-registered GP is £40. Same-day appointments are usually available, 6am to 10pm, seven days a week.

Who is invited

Men are invited once, in the year they turn 65. One appointment, one scan, and for the great majority that is the end of it — they are discharged and never need another.

It is the shortest and least demanding screening programme the NHS runs, and the one people are least likely to have heard of.

Over 65 and never screened?

You can refer yourself. Contact your local AAA screening service and ask for a scan.

This applies to any man over 65 who was never invited or did not attend — which includes a great many men who moved, changed GP, or simply binned the letter. Risk rises with age, so being older is a reason to do it, not a reason it has passed you by.

Why women are not invited

Abdominal aortic aneurysms are far less common in women, and rupture at smaller sizes and older ages. The trials that established the benefit of screening were conducted in men, and screening women has not been shown to produce the same benefit.

That is the honest answer — not that women do not get them, but that population screening has not been demonstrated to help. Women with a strong family history or symptoms should still be assessed on their own merits.

Higher risk — worth raising early

If your father or a brother had an aortic aneurysm, your risk is substantially higher. First-degree relatives of people with AAA are sometimes offered surveillance earlier than 65, and it is worth asking rather than waiting.

What happens

The scan

Ten to fifteen minutes, and completely painless.

  • You lie down and lift your shirt
  • Cool gel is put on your abdomen
  • An ultrasound probe is moved over it for a few minutes
  • No needles, no radiation, no preparation, no fasting

You are usually told the result before you leave.

What is measured

The width of the aorta, the main artery running down through your abdomen. A normal aorta is under 3cm across.

The four possible outcomes

  • Under 3cm — normal. Around 98 in 100 men. You are discharged and will not be invited again, because an aorta that is normal at 65 very rarely goes on to become dangerous
  • 3.0 to 4.4cm — small aneurysm. A scan once a year to watch it
  • 4.5 to 5.4cm — medium aneurysm. A scan every three months
  • 5.5cm or more — large aneurysm. Referral to a vascular surgeon, usually within two weeks, to discuss repair

If an aneurysm is found

Most are small and never need surgery. Surveillance exists because the risk of rupture is very low below 5.5cm, and the risk of the operation is not — so watching is genuinely the safer option, not a delay.

Why it matters

An abdominal aortic aneurysm causes no symptoms at all until it ruptures. There is no warning, no gradual decline, and nothing you would notice.

When one ruptures, around 8 in 10 people die — many before reaching hospital.

When one is repaired electively, having been found by screening, the great majority of men survive and recover.

That gap is the entire argument for this programme, and it is a stark one. Ten minutes lying on a couch with gel on your stomach, against a condition that otherwise announces itself by killing you.

What screening achieves

  • Randomised trials showed screening reduces deaths from ruptured aneurysm in men
  • It allows planned repair rather than emergency surgery, and the difference in survival between the two is enormous
  • For men with a small aneurysm, it starts the conversation about smoking — which is the single biggest thing that determines whether it grows

Had a result or an invitation you want explained?

Book a consultation

What the evidence shows

  • Randomised controlled trials demonstrated that ultrasound screening of men aged 65 reduces mortality from abdominal aortic aneurysm, and the benefit persists over long-term follow-up
  • A single negative scan at 65 is sufficient — the risk of a man with a normal aorta at that age subsequently developing a clinically significant aneurysm is very low, which is why the programme does not repeat
  • Elective repair is recommended at 5.5cm or above, where the risk of rupture begins to exceed the risk of the operation
  • Below 5.5cm, surveillance rather than surgery is recommended, since early repair has not been shown to improve survival
  • Smoking is the strongest modifiable risk factor both for developing an aneurysm and for the rate at which it grows
  • Screening has not been shown to produce equivalent benefit in women, which is why the programme is offered to men only

This is one of the more clear-cut screening programmes in terms of the balance of benefit to harm, largely because the test is quick, harmless, and answers the question definitively for most men in one go.

Uptake and barriers

The numbers

Around three quarters to four fifths of invited men attend, which is comparatively good — but it still leaves a substantial number unscreened, and they are disproportionately the men at highest risk.

Who misses out

  • Men who smoke — who are both least likely to attend and most likely to have an aneurysm. That is the worst possible combination and it is well documented
  • Men in more deprived areas
  • Men who have moved recently, since the invitation goes to the address the GP holds
  • Men who did not recognise what the letter was about

The reasons, and the answers

  • "I've never heard of it." Most people have not. It is an ultrasound of your stomach that takes ten minutes
  • "I feel fine." Everyone with an aneurysm feels fine. That is the defining feature of the condition
  • "Will it hurt?" No. Gel and a probe. Nothing else
  • "I'd rather not know." Worth weighing against the fact that a rupture kills most people it happens to, and a planned repair does not
  • "I lost the letter." Ring the local service and book yourself in

If you are reading this about your father or husband

Ask him whether he went. This is a programme where a nudge from a family member demonstrably changes attendance, and where the men least likely to go are the ones who most need to.

If you miss it

You can still be scanned

  • Contact your local AAA screening service directly and ask — you do not need a GP referral
  • Any man over 65 who has never been screened can self-refer, at any age beyond that
  • Missing the invitation does not remove your entitlement

Symptoms — call 999

A ruptured or rapidly expanding aneurysm is a life-threatening emergency. Call 999 immediately for:

  • Sudden severe pain in the abdomen, or in the lower back
  • A pulsating feeling in the abdomen, with pain
  • Feeling faint, collapsing, or going pale and clammy with abdominal or back pain

Say that you have, or may have, an aortic aneurysm. It changes what happens next in the ambulance and at the hospital.

If you are under surveillance

Attend the follow-up scans. They exist so that repair can be timed properly, and missing them defeats the point of having been found.

Limitations and harms

What it does not do

  • It looks at the abdominal aorta and nothing else. It is not an abdominal check-up, and it says nothing about your kidneys, liver, bowel or anything else
  • It does not detect aneurysms of the chest aorta, which are a separate condition
  • It does not assess your heart or your general cardiovascular risk

The harms, stated properly

  • Anxiety from surveillance. Being told you have a small aneurysm and then being scanned yearly is a real psychological burden for some men, particularly since most of those aneurysms will never need anything done
  • Finding aneurysms that would never have ruptured, and monitoring them for years unnecessarily
  • The risk of surgery itself, in men who go on to repair. It is major surgery with real mortality, which is precisely why the 5.5cm threshold exists rather than operating on everything found
  • Occasionally, a scan cannot see the aorta clearly — usually because of bowel gas or body habitus — and needs repeating

Driving — the thing nobody mentions

If you are found to have a large aneurysm, there are DVLA implications, and people are frequently unaware of them.

  • Car and motorcycle drivers must notify the DVLA if the aneurysm reaches 6cm, and must stop driving at 6.5cm or above
  • Bus, coach and lorry licences are considerably stricter, with disqualification at a smaller diameter

If this affects your livelihood, raise it early rather than discovering it late. We can go through it with you.

The balance

For this programme the balance is favourable and reasonably uncontroversial. The test is harmless, the answer is usually definitive and permanent, and the condition it looks for is otherwise silent and usually fatal.

Common questions

What actually is an aortic aneurysm?

A swelling in the main artery running down through your abdomen. The wall weakens and stretches over years.

It causes nothing at all until it bursts, which is why it is screened for rather than waited for.

Does the scan hurt?

Not at all. Gel on your stomach and a probe moved over it for a few minutes.

No needles, no radiation, no fasting, no preparation. You can eat beforehand and drive afterwards.

Why only once?

Because a normal aorta at 65 very rarely becomes dangerous later. The evidence supports a single scan at that age.

If yours is normal you are discharged, and that is a genuine answer rather than a cost saving.

Why are women not offered it?

Because screening has not been shown to produce the same benefit in women. Aneurysms are much less common in women and behave differently.

Women with a strong family history or symptoms should still be assessed individually — the programme's absence is not a statement that it never happens.

I am 71 and was never invited. Can I still go?

Yes — contact your local AAA screening service and refer yourself. No GP referral needed.

Being older is a reason to do it, not a reason you have missed the window.

They found a small aneurysm. Do I need an operation?

Almost certainly not. Most small aneurysms never reach the size at which surgery is worthwhile.

Surveillance is the safer option below 5.5cm, because the risk of the operation exceeds the risk of rupture at that size.

What is the most useful thing I can do if I have one?

Stop smoking. It is by a distance the biggest influence on how fast an aneurysm grows.

Also: keep blood pressure controlled, stay active, and attend the follow-up scans. NHS stop smoking services are free.

Does it run in families?

Yes — having a father or brother with one raises your risk substantially.

Mention it to your GP rather than waiting for 65, since earlier surveillance is sometimes offered to first-degree relatives.

Will it affect my driving licence?

Only if it becomes large. Car drivers must notify the DVLA at 6cm and stop driving at 6.5cm; lorry and bus licences have stricter limits.

If you drive for a living, raise this early — it is frequently not mentioned until it becomes a problem.

Should I pay for a private scan instead?

No reason to. The NHS scan is free, quick and uses the same ultrasound.

If you are outside the programme, self-referral costs nothing — use that before paying anyone.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
