Most aortic aneurysms are found by accident.
Most people carrying an abdominal aortic aneurysm have no symptoms at all. Discovery usually happens by accident, while someone is being scanned for a kidney stone or a sore back and the aorta happens to be in frame. The Society for Vascular Surgery says so plainly. Nobody was looking.
Formal aortic aneurysm screening exists. What it covers is narrower than anyone assumes, because the U.S. Preventive Services Task Force recommends one ultrasound for men 65 to 75 with a smoking history and stops. Medicare pays for a single scan per lifetime. That is the programme.
Are you a woman, a lifelong non-smoker, or under 65? Then the guideline does not send you anywhere at all. Your own doctor can still order the scan, though outside those criteria an insurer is under no obligation to pay.
Start with the word itself, because what counts as an aneurysm is smaller than most people picture.
What an Aortic Aneurysm Is, and Why It Gives So Little Warning
The aorta is the largest artery you have. It runs from the heart through the chest and abdomen before splitting toward the legs, and a weakened section lets blood pressure push the wall outward until it balloons. The bulge is an aortic aneurysm. Nothing more complicated.
Size decides everything here. Measure a normal abdominal aorta and you get roughly 2.0 cm, according to the evidence review for the Task Force. Cross 3.0 cm and it is an aneurysm. One centimeter, then, separates a normal artery from one that needs watching.
An aortic aneurysm that stays quiet is not dormant. Slowly, out of sight, it grows, and the bigger it gets the faster it goes until two things wait at the end of that curve. Neither gives notice. Neither waits for symptoms.
Layers of the artery wall can split apart, which doctors call a dissection, or the wall gives way completely into a rupture. Between them they account for most deaths from aortic aneurysms, according to the CDC overview of aortic aneurysm.
Aortic aneurysms develop and grow before causing any symptoms, the National Heart, Lung, and Blood Institute notes. Hence the word silent. The same pattern runs through vascular disease generally, where blockages and narrowing build for years without announcing themselves.
When symptoms arrive at all, they are vague. Throbbing or deep pain in the back or side appears on the CDC list, along with pain in the buttocks, groin or legs, none of it pointing anywhere obvious. Sudden severe abdominal or back pain is different. Treat that one as an emergency.

Estimated share of patients who die if the aneurysm ruptures
Rupture mortality reframes the whole topic. An estimated 81 percent of patients die once an aneurysm ruptures, per the evidence review for the Task Force. Roughly a third never reach a hospital, which puts nearly all the benefit in finding it early.
Who Qualifies for Aortic Aneurysm Screening, and Who the Guidelines Leave Out
Aortic aneurysm screening rules run more specific than people expect. Finalized in 2019, the Task Force recommendation on abdominal aortic aneurysm splits the adult population four separate ways, by age, by sex, and by smoking history. Exactly one group gets a clear yes. The rest get hedges.
| Who you are | What the Task Force recommends | Grade |
|---|---|---|
| Men 65 to 75 with a smoking history | One-time ultrasound screening | B |
| Men 65 to 75 who never smoked | Offered case by case, not routinely | C |
| Women who never smoked, no family history | Routine screening not recommended | D |
| Women 65 to 75 who smoked or have family history | Evidence is insufficient to call it either way | I |
Coverage follows that same narrow shape. Medicare pays for one AAA screening ultrasound, once in a lifetime, and only for people it counts as at risk. Before any of that can happen, your own provider has to write you a referral.
Medicare’s definition of at risk is short. A family history of abdominal aortic aneurysms counts, and so does being a man between 65 and 75 who has smoked at least 100 cigarettes. The list ends there. No other route qualifies.
Read the two rules together and the gap gets wide. A 58-year-old whose father had an aneurysm repaired sits seven years outside the age window. Twenty years of smoking puts a 67-year-old woman in the group nobody has been able to rule on.
Neither of them qualifies for the covered scan. Women carry a much lower rate of aortic aneurysms overall. They are also up to four times more likely to rupture, the evidence review reports, which is the half that gets missed.
Family history carries weight. A parent or sibling with an AAA makes you 12 times more likely to develop one. Between 15 and 25 percent of people needing repair have a close relative with it, and both figures come from the Society for Vascular Surgery. Neither is small.
Smoking history moves the math further than any other single factor. One U.S. cohort put the lifetime risk of an aortic aneurysm at 10.5 percent for current smokers and 6.3 percent for former smokers. Never-smokers came in at 2 percent.
Smoking and blood pressure drive coronary plaque too, which is why a calcium score reading of your coronary arteries often lands in the same conversation. Atherosclerosis is a documented risk factor for both. The two tests look in different places, though, and that distinction matters.
How an Aortic Aneurysm Is Detected, and Which Scan Sees It
Ultrasound is the standard tool for aortic aneurysm screening. The evidence review prepared for the Task Force puts it ahead of both physical examination and CT scans, on grounds of cost and comfort. A clinic can run one quickly. Nothing else comes close.
Hands are not a substitute. One case-control study put the sensitivity of feeling for a 3.0 cm aneurysm at 68 percent. A meta-analysis of screening studies came in far lower, at 39 percent, so palpation misses more than it finds.
CT arrives later in the sequence. Once an aneurysm is known, a CT angiogram maps its size, location and extent, which is exactly what a surgeon needs before planning a repair. The Society for Vascular Surgery describes it that way. Different job entirely.
A third route exists, and it catches most aneurysms. Any CT covering the abdomen shows the aorta whether or not somebody went looking. Call it the incidental finding, which is why an abdominal CT reveals so much beyond its original question.
Radiation is the fair objection here, and it deserves a straight answer. A low-dose screening CT does not deliver the exposure of a diagnostic study with contrast. The numbers sit side by side in our breakdown of full body scan safety.
Which door you walk through decides what aortic aneurysm screening actually costs you.
| How you get screened | What it costs you | What it takes |
|---|---|---|
| Medicare AAA screening ultrasound | Covered by Part B | A referral, an at-risk qualification, and one use per lifetime |
| Ultrasound your own doctor orders | Varies by plan | A referral, and coverage is not guaranteed outside the criteria |
| Craft Body Scan Full Body Scan | $2,495 private-pay | No referral, no insurance pre-authorization, age 40 and up |
Before you decide
Match the price to what the scan actually covers
Every scan on the price list states which part of you it images, so you can pick the one that reaches the area you are worried about. Booking needs no referral and no insurance pre-authorization.
Getting looked at is only the first half of aortic aneurysm screening. Most people get lost at what comes immediately next. One number on that report drives every decision that follows it, and almost nobody explains what the number means.
What Your Measurement Means, and How Dangerous Each Size Is
Anything from 3.0 cm up counts as an aneurysm. Almost none go straight to surgery, though, because the size bands decide the response long before a surgeon does. Small means 3.0 to 5.4 cm, large starts at 5.5. More than 90 percent of screening-detected aneurysms never reach that mark.
Small ones get watched instead of treated. Repeat ultrasound every 6 to 12 months is the advice for anything under 5 cm, from the Society for Vascular Surgery. Rupture risk stays low there, so watching is the treatment, alongside blood pressure control and quitting smoking.
Growth rates explain why the interval tightens as the number climbs. Average growth in men ran 1.3 mm a year at 3.0 cm. Reach 5.0 cm and that nearly triples, to 3.6 mm a year in the review’s pooled patient data.
So how dangerous is a 4 cm aortic aneurysm, or a 5 cm one? In men, rupture rates climbed from 0.05 per 100 person-years at 3.0 cm to 0.64 at 5.0 cm, roughly a doubling for every extra half centimeter. Low, in other words. Low but not static.
| Measurement | What it is called | What usually happens next |
|---|---|---|
| Under 3.0 cm | Not an aneurysm | Nothing further for the aorta |
| 3.0 to 5.4 cm | Small aneurysm | Repeat ultrasound every 6 to 12 months, plus risk-factor control |
| 5.0 to 5.4 cm in women | Repair range for women | Repair considered at a smaller size than in men |
| 5.5 cm or larger | Large aneurysm | Referral to a vascular surgeon to discuss repair |
Sex changes the threshold, which surprises people. The repair trials ran mostly in men, so 5.5 cm came out of male data. For women, the Society for Vascular Surgery guidance on aneurysms recommends repair between 5.0 and 5.4 cm. Half a centimeter, and it matters.
Every number above depends on one thing happening first. None of them exist until somebody actually goes and images your aorta. Rationing that one step is exactly what the guidelines do, and a measurement nobody took cannot be acted on.
Where a Full Body Scan Fits Into Aortic Aneurysm Screening
Here is the part most pages skip. A full body CT is not the guideline-recommended screening test for an abdominal aortic aneurysm, and any provider telling you otherwise is selling past the evidence. Ultrasound holds that role. We are not going to pretend otherwise.
What a full body scan does is cover the territory. Our Full Body Scan images the heart, lungs, abdomen and pelvis in one visit. The abdominal aorta falls inside that field of view, and aneurysms are on the list it flags.
Think of it as the incidental finding, run on purpose instead of by luck. You are not waiting for a kidney stone to send you into a scanner. A board-certified radiologist reviews every scan, with your report back within 5 to 10 business days and guidance on anything flagged.
Which scan you pick decides what gets seen. Not every scan we offer reaches the abdomen, and a heart scan will never measure your aorta. The table below sets out what each scan covers, side by side, so the gaps are obvious.
| Scan | Price | Does it cover the abdominal aorta? |
|---|---|---|
| Full Body Scan | $2,495 | Yes, it images the heart, lungs, abdomen, and pelvis |
| Heart Scan, calcium score | $640 | No, it scores plaque in the coronary arteries |
| Couples Heart and Lung Scan | $149 per couple | No, the chest only |
| Whole Body MRI, Tulsa only | $2,999 | Yes, head to pelvis with no radiation |
A scan reports what is there on the day it is taken. It might flag an aortic aneurysm and hand you a measurement to act on. It might come back clear, and no imaging test anywhere can promise that nothing develops later.
Answers to Common Questions
What age do you screen for an aortic aneurysm?
Ages 65 to 75 is the window in the Task Force recommendation. Medicare’s covered ultrasound uses the same one for men with a smoking history. Two other U.S. guidelines start at 55 or 60 where family history is involved, per the evidence review.
Are there warning signs before an aortic aneurysm ruptures?
Usually not. Abdominal aortic aneurysms often produce no symptoms at all, per the CDC. Throbbing or deep pain in the back or side can show up, along with pain in the buttocks, groin or legs. Sudden severe abdominal or back pain is an emergency.
What is the best test for an abdominal aortic aneurysm?
Abdominal ultrasound. The Task Force evidence review prefers it over both physical examination and CT for screening. A CT angiogram only comes later, once an aneurysm is known and a surgeon needs its exact size and location.
How often should an aortic aneurysm be checked?
Size decides. Repeat ultrasound every 6 to 12 months is the Society for Vascular Surgery’s advice for anything under 5 cm. Larger or fast-growing aneurysms move to a vascular surgeon for a repair discussion instead of continued watching.
How dangerous is a 4 cm aortic aneurysm?
Low, at that size. Measured per 100 person-years in men, rupture runs about 0.05 at 3.0 cm and 0.64 at 5.0 cm, with every half centimeter roughly doubling the rate. Guidelines watch a 4 cm aneurysm rather than operate on it. More than 90 percent of aneurysms found by screening sit below the surgical threshold.
Does Medicare cover aortic aneurysm screening?
Yes, once. Medicare Part B covers one AAA screening ultrasound per lifetime for people it counts as at risk. The bar is a family history of abdominal aortic aneurysms, or a man 65 to 75 who has smoked at least 100 cigarettes. A referral is required.
How much does aortic aneurysm screening cost without insurance?
Provider and test both change the answer. Our Full Body Scan images the abdomen and pelvis along with the heart and lungs. The price is $2,495 private-pay, with no referral or insurance pre-authorization needed. A screening ultrasound ordered through a clinic is priced separately by that clinic.
Should women get screened for an aortic aneurysm?
For women who never smoked and have no family history, the Task Force recommends against routine screening. Where a woman 65 to 75 did smoke or does have a family history, it found the evidence insufficient either way. Women are also up to four times more likely to rupture, which makes this worth raising with your doctor.
Can a full body scan find an aortic aneurysm?
It can. A full body CT covers the abdomen, so the aorta sits in the field of view. An aneurysm can be flagged and measured there, though the guideline-recommended screening test for that specific purpose remains ultrasound.
If the guidelines skipped you
Get your abdomen looked at anyway
Maybe a parent or sibling had an aneurysm. Maybe you smoked and you are 58 instead of 65, or you are a woman the guideline could not rule on. Nobody is sending you for that ultrasound. The Full Body Scan covers the abdomen and pelvis for $2,495, and it needs no referral. A board-certified radiologist reads every image, with results back in 5 to 10 business days. Schedule your Craft Body Scan today and take the first step toward early detection.
