Vascular Filling Defect Angiogram (Contrast Study)

What to Expect Before the Test

You’ll likely need to fast for a few hours before the test, depending on your doctor’s instructions. Wear comfortable clothing and remove any jewelry or metal objects that could interfere with imaging. Inform your doctor about any allergies, especially to contrast dye, and let them know if you’re pregnant or breastfeeding.

During the Procedure

A nurse or technician will insert a thin tube (catheter) into a blood vessel, usually in your arm or groin. A contrast dye will be slowly injected to highlight the blood vessels on X-ray images. You may feel a brief pinch or pressure, but the procedure is generally quick and painless. You’ll lie still while images are taken.

After the Procedure

You’ll be monitored for a short time to ensure there are no immediate reactions to the contrast dye, such as dizziness or swelling. Avoid strenuous activity for a few hours afterward. Follow your doctor’s instructions for any post-procedure care, such as keeping the injection site dry or managing any minor discomfort.

Why This Test Is Done

Doctors order this test to diagnose or monitor conditions like peripheral artery disease, aortic aneurysms, or other vascular abnormalities. It can also help plan treatments, such as angioplasty or bypass surgery, by showing the exact location and severity of blockages or narrowing.
