Cardiac arteriogram

Definition

Aortic angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the aorta, the major artery leading out of the heart.

Alternative Names

Angiography - aorta; Aortography

How the test is performed

Before the test starts, you will be given a mild sedative to help you relax.

An area of your body, usually in your arm or groin area, is cleaned and numbed with a local numbing medicine (anesthetic). A radiologist or cardiologist makes a small surgical cut in an artery in the cleansed area, and then inserts a thin hollow tube called a catheter.

The catheter is placed through the artery and carefully moved up into the aorta. The doctor can see live images of the area on a TV-like monitor, and uses them to guide the catheter to the correct position.

Once the catheter is in place, dye (contrast material) is injected into catheter. X-ray images are taken to see how the dye moves through the artery. The dye helps highlight any blockages in blood flow.

How to prepare for the test

You will be asked not to eat or drink anything for 6-8 hours before the test.

The test will be done in the hospital. You may be told to check into the hospital the night before the test. If not, you will be admitted as an outpatient or inpatient the morning of the procedure.

You will be asked to wear a hospital gown and sign a consent form for the procedure.

How the test will feel

You will be awake during the test. You may feel a sting as the numbing medicine is given and some pressure as the catheter is inserted. You may feel a warm flushing when the contrast dye flows through the catheter. This is normal and usually goes away within a few seconds.

You may have some discomfort from lying on the hospital table and staying still for a long time.

Pressure is immediately applied to the puncture site for 10-15 minutes to stop the bleeding. After that time the area is checked and a tight bandage is applied. The leg should be kept straight for an additional 4 hours after the procedure.

Generally, normal activity may be resumed the day after the procedure.
