Abdominal Aortic Aneurysm (AAA)—1000-Person Tool
We recommend one-time screening with ultrasound for AAA in men aged 65 to 80.
We recommend not screening men older than 80 years for AAA.
We recommend not screening women for AAA.
- Screening involves examining someone who does not show symptoms of a condition or illness.
- Screening uses a specific tool to identify a condition or illness.
- AAA is a weakening in the wall of the aorta that bulges due to pressure from blood flow.
- Male sex, family history, and older age are all associated with an increased risk of AAA.
- Being a current or former smoker is also an important risk factor for AAA.
- Women are less likely to have an AAA, and there is no evidence that screening has a positive impact on their health.
1000 men aged 65 to 80 who get screened*
- 45 Men with an AAA identified from a screen and monitored each year depending on the size of the AAA (<5.5 cm)
- 8 Men who undergo an elective procedure‡
- 2 Men who experience a ruptured AAA
- 2 Men who die from their AAA (rupture or complications)
1000 men aged 65 to 80 who are not screened*
- 0† Men with an AAA identified from a screen and monitored each year depending on the size of the AAA (<5.5 cm)
- 3 Men who undergo an elective procedure‡
- 4 Men who experience a ruptured AAA
- 3 Men who die from their AAA (rupture or complications)
*Follow-up period of 3–5 years.
†If you are not screened, your AAA is not identified by a screening test.
‡ Surgery that is planned in advance, rather than in an emergency.
Screening is a personal decision. It is important that you weigh the benefits and harms for yourself and then discuss your decision with your primary care provider.
