An aorta duplex scan is a test that uses sound waves to image the aorta (the main blood vessel leading away from the heart). The size of the aorta is examined.
Why you are having this procedure (symptoms/indications):
Your doctor may have ordered an aorta duplex scan because you have a known or suspected aneurysm (a weak area in the wall of the artery that expands or bulges).
Prep for the procedure:
You should not eat or drink after midnight the day of the test. Do not smoke or chew gum. If you are diabetic, you may have a light breakfast and take your insulin. You should take your medicines with small sips of water.
What to expect:
You will have to remove your clothing above the waist and wear a gown. You will be asked to lie on your back during the test. You may be asked to change positions during the test. The lights in the room will be dim. The sonographer will place a probe (ultrasound transducer) with gel on it on your abdomen. The probe will be moved around your abdomen to see different views of your aorta. The test will take about 30 minutes to complete.
There are no known risks associated with this test.
Post procedure instructions/limitations:
You may resume your normal activities immediately following the test.
