Abdominal Aortic Aneurysm (AAA) Scan
The aorta is the major artery responsible for carrying blood away from the heart. There are many branches off the aorta. These include arteries that carry blood to the kidneys and legs.
Ultrasound testing (imaging) is used to examine arterial conditions in the abdominal aorta and its branches. One of the most important conditions detected by an abdominal artery evaluation is an abdominal aortic aneurysm (AAA). An abdominal aortic aneurysm is caused when the lining in the wall of the aorta becomes weak, resulting in an abnormal ballooning or enlargement. An AAA occurs in the abdominal portion of the aorta and is the most fatal form of vascular disease.
What to expect during the test
- You may be asked to remove some articles of clothing and change into a gown.
- An abdominal artery evaluation requires special preparation. You should not eat or drink anything (except medications) for 4 hours prior to the test. The test is completely safe and painless.
- You will lie on your back while a technologist places a sensor on several areas of your abdomen. The sensor will have a small amount of cool gel on the end. The gel helps produce clearer pictures, and will not harm your skin.
- The only discomfort you may feel is the coolness from the gel or slight pressure from the sensor as it moves along your body.
- You may hear swooshing sounds during the test as the sound waves are detected.
What to expect after the test
- If your scan results are normal you may resume your regular activities immediately following the scan.
- A vascular surgeon will use your scan to assess any blockages or abnormalities in your aorta.
- If your results are abnormal, your physician will be contacted immediately and you may be admitted to the hospital for further tests or treatment.
- Results from your scan will be prepared by the vascular surgeon, and a report will be mailed to your primary care physician.
If you have any questions about your care after you return home, call your physician's office.
