Vascular Filling Defect Angiogram (Contrast Study)

What Is an Angiogram Used For?

An angiogram visualizes blood vessels after injecting a dye that makes them visible on X-ray. This helps detect issues such as stenosis (narrowing), aneurysms (ballooning), or vascular malformations. It’s commonly used for diagnosing vascular diseases, planning surgeries, or guiding treatments like angioplasty.

Common Conditions Evaluated

This test is often performed to evaluate conditions like peripheral artery disease, aortic aneurysms, carotid artery blockages, or venous disorders. It may also assess vascular access sites (e.g., for dialysis) or guide interventions like stent placement.

Procedure Overview

You’ll lie on a table while a catheter is inserted into a blood vessel (usually in the arm or groin). A contrast dye is injected, and real-time X-ray images capture blood flow. The procedure is usually quick but may cause mild discomfort or bruising.

Preparation & Risks

No special prep is needed, but you may be asked to stop certain medications or fasting. Risks include allergic reactions to dye, bleeding, or temporary nerve damage. Doctors will monitor you closely during and after the procedure.
