Abdominal Aortic Aneurysm: Should I Get a Screening Test?

You may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them.

Abdominal Aortic Aneurysm: Should I Get a Screening Test?

Get the facts

Your options

  • Get a screening test for abdominal aortic aneurysm.
  • Don't get a screening test.

If you already have symptoms of an abdominal aortic aneurysm and your doctor suspects that you have one, this topic is not for you. Your doctor will want you to have the test.

Key points to remember

  • Most abdominal aortic aneurysms, or AAAs, never cause problems. But sometimes they burst, which is often deadly.
  • Screening can find these aneurysms before they burst.
  • Screening can be harmful for some people, because it can also find aneurysms that will never cause problems. This may lead to dangerous surgery that isn't really needed.
  • People who are at higher risk for AAAs will get the most benefit from this test. You are at higher risk if you are a man who is age 65 to 75 and you have ever smoked.
FAQs

What is an abdominal aortic aneurysm (AAA)?

An aortic aneurysm (say "a-OR-tik AN-yuh-rih-zum") is a bulge in part of the aorta, the body's main artery. When this bulge is in the belly (abdomen), it's called an abdominal aortic aneurysm. It's often called "triple A" or "AAA" for short.

These bulges are most common in men older than age 65, people with high blood pressure, and people who smoke. AAAs sometimes run in families.

Most aortic aneurysms never cause problems, especially if they're small, don't cause symptoms, and don't grow fast.

But if the bulge gets too big, it can burst, or rupture, which is often deadly.

What is the treatment for AAA?

When the bulge is small, not causing symptoms, and not growing fast, it is safe to watch it carefully and wait to have treatment. Small aneurysms rarely rupture.

Repair of the aneurysm is usually recommended if the AAA is large, causing symptoms, or is growing fast.

There are two ways to repair an aneurysm. One is traditional open surgery. The other is a less invasive procedure called endovascular repair, during which a tube called a stent graft is inserted through an artery in the groin.

What is the screening test for AAA?

Screening tests help your doctor look for a certain disease or condition before any symptoms appear. The AAA screening test is an ultrasound test. You lie on a table while a technician does the test. After the test, a radiologist looks at the pictures to see if you have an aneurysm.

AAA screening is fast and painless. It is usually done in the doctor's office or at a hospital.

What are the benefits?

  • AAA screening can find large bulges that might rupture if they are not repaired.
  • Screening can also find smaller bulges that can be watched carefully over the years.
  • A study of men ages 65 and older showed that those who have the screening are less likely to die of AAA rupture.footnote 1

What are the risks?

It may seem obvious that AAA screening is good, because it might save your life by finding a bulge before it bursts. The test itself doesn't have risks. But what if you learn during the test that you have a bulge in your aorta? There's no way to know for sure if the bulge will rupture in the future. So you might decide to have surgery or a procedure to fix it. That's where the risks are.

Repairing an AAA can be very risky. The benefits outweigh the risks when the aneurysm is at risk of bursting. Repair of an AAA can cause problems later, like blood clots or problems with the stent graft in the aorta. And some people die during the operation or soon after.

  • With open surgery (the surgeon makes a large cut in the belly and repairs the aorta), about 5 out of 100 people die during surgery or within 30 days.footnote 2 That means about 95 out of 100 people don't die during surgery or within 30 days.
  • With an endovascular procedure, in which the surgeon inserts a tube called a stent graft through an artery in the groin, 1 or 2 out of 100 people die within 30 days.footnote 2 That means 98 or 99 out of 100 people don't die within 30 days.

You can see why it's so important to talk to your doctor about whether the benefits of AAA screening outweigh the risks in your case.

Why might your doctor recommend screening?

Not all doctors agree on who should be screened for abdominal aortic aneurysm. Talk to your doctor about whether the benefits of screening would outweigh the risks in your case.

The U.S. Preventive Services Task Force recommends a screening test for men who are ages 65 to 75 and have ever smoked.footnote 3

Some doctors think that men 65 years and older should be screened if they have a family history of abdominal aortic aneurysm.

The U.S. Preventive Services Task Force does not recommend screening for women who have never smoked and have no family history of abdominal aortic aneurysm.footnote 3

Women have a lower risk for an aneurysm than men do. But some doctors think that certain women should be screened. Some recommend screening for women who are 65 and older and either have smoked or have a family history of abdominal aortic aneurysm.

Get screened for AAA Get screened for AAA
  • You lie on your back on a table for the ultrasound. Warmed gel is spread on your belly. Then a small handheld device is pressed against your belly and moved back and forth over it.
  • When the ultrasound is done, you may be asked to wait while a doctor looks at the pictures to see if you have an aneurysm.
  • The screening usually takes 30 to 60 minutes.
  • AAA screening can find a dangerously large aneurysm before it bursts.
  • It can also find smaller AAAs that can be watched in the future.
  • The test results may motivate you to stop smoking.
  • The test could lead you to have a risky surgery or procedure to fix an aneurysm that may never have caused trouble.
  • You may have a lot of worry if the test finds a large AAA but you can't have it repaired because you have other health problems.
Don't get screened for AAA Don't get screened for AAA
  • If you have an AAA, it might be found during a routine physical exam or during an X-ray, ultrasound, or echocardiogram that's being done for other reasons.
  • If you smoke, you could quit smoking to lower your risk of getting an abdominal aortic aneurysm.
  • You avoid having to make a decision about whether to have an aneurysm repaired.
  • You avoid the worry that might come from learning that you have an aneurysm, even though it may never cause you problems.
  • You could have an aneurysm that remains undetected until it ruptures. A rupture is very dangerous.

Personal stories about considering AAA screening

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

I have high blood pressure, and I'm a smoker. I've heard about AAAs and how people usually die when they burst. It's pretty scary. I figure it can't hurt to have the test. And I'll just feel better, because either I'll know I don't have an aneurysm or I'll find out I do have one and I can get treatment.

Hayden, age 59

My father died when his aneurysm ruptured. So I've been worried about my risk and decided to ask my doctor about it. She explained why this screening probably isn't for me, because even though I have a family history, I'm a woman, and my risk just isn't that high. I'm going to skip this test.

Sharon, age 65

I've never been a smoker, but I do have high blood pressure and high cholesterol. So I'm nervous about having an aneurysm that could rupture and maybe kill me. I'm going to ask my doctor if I need to get screened.

Jerry, age 68

I smoked in college, but that was decades ago. My doctor says my heart is healthy. If I had the test and they found a small aneurysm, I'd worry about it all the time, probably for no reason. No, thanks! I'm not going to have the test now. Maybe in a few years, when my risk is higher.

Abed, age 60

1. Does AAA screening help prevent death from ruptured aneurysms?

  • Yes

That's right. Screening can find AAAs before they rupture, and a ruptured aneurysm is often deadly.

That's right. Although the test itself is harmless, it could lead you to have risky surgery on an aneurysm that may never have caused a problem.

3. Which group is most likely to get AAAs?

  • Women
  • Men age 45 to 60
