Written by AAA Screening (Men 65+): What to Expect, Who’s Invited, and Why It Matters
What is AAA screening?
AAA screening is a quick ultrasound of the tummy (abdomen) to check the size of your aorta—the main blood vessel supplying your body. The aim is to find an abdominal aortic aneurysm (AAA) early, before it becomes dangerous.
It’s a one-off scan for most men. If an aneurysm is found, you’ll enter a regular monitoring plan to keep you safe and decide if/when treatment is needed.
Who gets invited in the UK?
- England: All men are invited in the year they turn 65. If you’re over 65 and haven’t been scanned, you can self-refer.
- Inclusive language: Anyone assigned male at birth (including some trans women and some non-binary people) may be eligible—ask your GP or local screening service.
- Women: Not routinely invited because population risk is much lower; targeted research continues. If you’re concerned (e.g., strong family history), speak to your GP.
What happens at the scan?
- A trained practitioner applies gel and moves a small handheld probe over your abdomen.
- The scan is painless and usually takes about 10 minutes.
- You’ll be told your result straight away, with next steps if needed.
Results & next steps
Your result is based on the diameter of the aorta measured on ultrasound:
- Normal (usually < 3.0 cm): no further scans needed.
- Small AAA (3.0–4.4 cm): annual ultrasound surveillance.
- Medium AAA (4.5–5.4 cm): ultrasound every 3 months.
- Large AAA (≥ 5.5 cm): referral to a vascular team to discuss treatment (open surgery or EVAR) and overall cardiovascular risk management.
Whatever your result, you’ll be supported with information on heart-healthy habits, smoking cessation, and medicines from your GP or vascular team where appropriate.
Benefits and possible harms
Benefits:
- Reduces deaths from ruptured AAA by finding aneurysms early and monitoring or treating them before they burst.
- Simple, quick, free ultrasound—no radiation.
Possible harms (rare):
- Over-diagnosis & anxiety: some small AAAs may never cause problems but still require follow-up.
- False reassurance: a normal scan at 65 doesn’t guarantee you’ll never develop an AAA later (risk remains low).
- Treatment risks: both open surgery and EVAR have benefits and risks; EVAR needs lifelong surveillance and may need re-interventions; open surgery has a higher short-term recovery burden but fewer late device-related issues.
Who is at higher risk?
- Smoking (current or past) — the strongest modifiable risk.
- Age & sex — risk rises with age; higher in men.
- Family history — first-degree relatives of someone with AAA have higher risk.
- High blood pressure, cardiovascular disease, and certain patterns of atherosclerosis.
- Ethnicity — historically more common in White men, though everyone can be affected.
Lesser-known, evidence-backed insights
- Prevalence is falling: Across UK and European programmes, the proportion of 65-year-old men with screen-detected AAA has declined over the last decade—likely linked to reduced smoking and improved cardiovascular prevention. Screening still saves lives, but fewer men now have AAAs at age 65 than in the past.
- Surveillance works: Men with small or medium AAAs managed in structured programmes have very low rupture rates while under follow-up.
- EVAR vs open: EVAR offers lower early operative risk but needs lifelong imaging and has higher late re-intervention/rupture than open repair; open repair has a tougher short-term recovery but fewer device-related problems long term. Your vascular team balances these trade-offs for you.
- Attendance matters: Non-attendance clusters with social isolation, lower educational level, and smoking—if you support someone at 65, a lift or reminder can help them benefit.
How to book or rebook
- If you’re turning 65: look out for your NHS invitation letter.
- If you’re 65+ and never attended: contact your local AAA screening service to self-refer (your letter will include details; your GP surgery can help if you don’t have them).
- Need adjustments? Tell the service if you need mobility, communication, or chaperone support—they can arrange this.
Tip: Bring a list of medicines and arrive with a comfortably empty stomach if possible—it can make scanning easier.
Red flags: when to seek urgent help
Call 999 or go to A&E immediately if you develop:
- Sudden, severe abdominal, back, or flank pain (may spread to groin/buttocks).
- Feeling faint/collapsing, cold sweaty skin, or severe breathlessness.
These symptoms can be caused by many things—but if an AAA ruptures, every minute counts.
FAQs
Do I need to prepare?
No special preparation. Wear loose clothing. You’ll get the result straight away.
I’m over 65 and never got a scan—am I too late?
No. You can still self-refer to your local AAA screening service.
Are women screened?
Not routinely. Population risk is lower and current evidence does not support national screening for women. If you’re worried (strong family history, smoker), speak to your GP.
Can lifestyle or medicines shrink an AAA?
No. But stopping smoking, controlling blood pressure, and managing heart risk are crucial—they reduce overall danger while you’re monitored or awaiting treatment.
If I’ve had EVAR, am I “done”?
No. EVAR needs lifelong surveillance scans to ensure the graft remains sealed and effective.
