What Is an Angiogram?

An angiogram is an X-ray imaging test used to look at the arteries and veins in your body. It can help diagnose conditions such as blockages in the arteries, aneurysms, clotting, and other heart and vascular problems. A special contrast dye, which contains iodine and is visible on X-ray images, is injected into the arteries of the body to highlight the vascular system in detail.

How Is an Angiogram Performed?

An angiogram is typically performed in a hospital or other healthcare facility. The procedure begins with the patient being given a sedative to help them relax. An intravenous (IV) line will be inserted into the vein, to both provide the contrast dye and monitor the patient’s vital signs. The contrast dye will then be injected into the artery with a thin catheter. As the dye travels through the artery, X-ray images will be taken to show the health of the blood vessels. The procedure usually takes 30-60 minutes.

What Are the Risks of an Angiogram?

There are some risks associated with angiograms, such as the risk of allergic reaction to the contrast dye, vomiting, temporary numbness or pain in the arm or leg, and sometimes a temporary increase in heart rate. Although rare, the risks of more serious complications such as stroke, heart attack, and inflammation of the artery wall can also occur. It is important to speak with your doctor about any potential risks before undergoing the procedure.

Overall, angiograms provide valuable insight into the health of the arteries, which can help diagnose and treat conditions that affect the cardiovascular system. If you have any questions or concerns about the procedure or its potential risks, be sure to speak to your doctor.
