What is an aorta-iliac ultrasound? An aorta-iliac ultrasound is a test using sound waves to form images of the aorta and iliac arteries. This is a non-invasive diagnostic exam done to look at any medical conditions that may affect blood flow to the groin, buttocks, legs, and feet.

Why might your doctor ask for this test? Your doctor may suggest this test if you are experiencing any of the following:

• Erectile dysfunction

• Gangrene

• Sore legs, feet, and toes

• Weakness in the hips or legs

How should I prepare? Leave any valuables or jewelry at home. It's best to wear loose fitting clothing for your test.

Avoid eating anything for eight hours before the exam. You may take any prescribed medications with small amounts of water.

How is the test performed? Your healthcare provider will ask for you to lay on an examination table. A gel will be placed on your abdomen and pelvis and the ultrasound wand, known as a transducer, will be used to examine the arteries in these areas. The test takes approximately an hour to complete.

Results: Once the test images are analyzed and given to your physician, they will go over any additional tests and treatments you may need.
