A groin duplex scan is a test that uses sound waves to image the blood flow to the arteries in the groin. The procedure is done after a heart catheterization or other interventional procedure. The arteries in the groin are examined to check for a pseudoaneurysm or false aneurysm (a leak in an artery causing blood to collect).
Why you are having this procedure (symptoms/indications):
Your doctor may have ordered a groin duplex scan to evaluate your groin pain or swelling after your interventional procedure. Your test may have been ordered because you have an abnormal sound in the groin arteries (bruit).
Prep for the procedure:
There is no preparation for the test.
What to expect:
You will have to remove your clothing 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 groin. The probe will be moved around your groin to see different views of your arteries. The test will take about 30 minutes to complete.
There are no known risks associated with this test.
Post procedure instructions/limitations:
If you test is negative, you may resume your normal activities immediately following the test.
