An abdominal aortic aneurysm (AAA) screening is a test used to detect a bulge or swelling in the aorta, the main artery that carries blood from the heart to the rest of the body. It is important to detect an AAA early, as it can be life-threatening if it ruptures.
Who should be screened for an abdominal aortic aneurysm?
Men aged 65-75 who have ever smoked are at the highest risk for AAA and should be screened. Men aged 65-75 who have never smoked should also be screened if they have a family history of AAA. Women aged 65-75 who have a family history of AAA should also be screened.
How is an abdominal aortic aneurysm screening done?
An AAA screening is done with an ultrasound. This is a painless test that uses sound waves to create an image of the aorta.
How do I prepare?
No special preparation is needed for an AAA screening.
What happens during the test?
During the test, you will lie on your back on an exam table. A technician will apply a warm gel to your abdomen and use a handheld device called a transducer to send sound waves into your abdomen. The sound waves create an image of the aorta on a computer screen.
What are the risks of this test?
An AAA screening is a safe and painless test. There is no radiation involved and no known risks associated with the test.
What do the results mean?
If the results of the test are normal, it means that there is no aneurysm present. If the results are abnormal, it means that an aneurysm is present and further testing may be needed.
If the results are abnormal, what are the next steps?
If the results of the test are abnormal, your healthcare provider may recommend further testing, such as a CT scan or MRI, to get a better look at the aneurysm.
When should I call my healthcare provider?
If you experience any pain or discomfort during or after the test, you should call your healthcare provider.
