What is this test?

Carotid arteriography is an X-ray-based imaging test that uses contrast material to show the carotid arteries in the lower neck. In this procedure, a catheter is introduced through the artery in the right groin.

Why might I need this test?

This test may be ordered to evaluate suspected narrowing, blockage, aneurysm, or another problem involving the carotid arteries. It can also help guide treatment for a stroke or another condition affecting blood flow to the brain.

How is the test performed?

After a small incision is made in the right groin, a thin catheter is guided to the arteries that supply the head. Contrast material is then injected, and X-ray images are taken to show the blood vessels.

How do I prepare for the test?

Follow your care team's instructions about eating, drinking, and medications. Tell the team if you have kidney disease, a previous contrast reaction, bleeding problems, or might be pregnant, because these factors may affect the procedure.

Frequently asked questions

Is carotid arteriography the same as a carotid ultrasound?
No. Arteriography uses an injected catheter and X-ray images, while carotid ultrasound uses sound waves to examine the arteries without an injection.
Will I feel the contrast injection?
You may feel a brief warm, flushing, or pressure-like sensation when contrast is injected. The care team will tell you what to expect and can help manage any discomfort.
Are there risks from the catheter or contrast?
Possible risks include bleeding at the groin, blood-vessel injury, allergic-like reactions to contrast, and kidney injury in people with kidney disease. Your clinician will review your individual risks before the procedure.
