Bilateral Carotid and Cervical Vessel Angiography With Contrast (Right Femoral Artery Access)

What is this test?

Carotid and cervical angiography is an X-ray-based procedure that uses contrast dye to show the major blood vessels in the neck. If the order specifies right femoral artery access, a catheter is typically inserted through a blood vessel in the groin and guided to the arteries being examined.

Why might I need this test?

This test may be ordered to evaluate reduced blood flow, a suspected blockage, an abnormal enlargement of an artery, or symptoms that could be related to a stroke or another vascular condition. It may also be performed before certain vascular procedures.

How is the test performed?

After a small catheter is placed in an artery, contrast dye is injected and X-ray images are taken as it travels through the vessels supplying the head and neck. Local anesthetic is generally used at the catheter insertion site, and you may be given medication to help you remain still.

How do I prepare for the test?

Follow your imaging center's instructions. Tell the care team about prior contrast reactions, kidney disease, bleeding problems, blood-thinning medicines, or possible pregnancy, because these details may affect the procedure or its preparation.
