Angiography - aorta; Aortography; Abdominal aorta angiogram; Aortic arteriogram
Aortic angiography is a procedure that uses a special dye and x-rays to see how blood flows through the aorta, the major artery leading out of the heart, and through your abdomen or belly.
Angiography is an imaging test that uses x-rays and a special dye to see inside the arteries. Arteries are blood vessels that carry blood away from the heart.
This test is done in a special unit of the hospital. Before the test starts, you will be given a mild sedative to help you relax.
After the x-rays or treatments are finished, the catheter is removed. Pressure is immediately applied to the puncture site for 20 - 45 minutes to stop the bleeding. After that time, the area is checked and a tight bandage is applied. The leg is usually kept straight for another 6 hours after the procedure.
You will be asked not to eat or drink anything for 6-8 hours before the test.
You will be asked to wear a hospital gown and sign a consent form for the procedure. Remove jewelry from the area being studied.
Tell your health care provider:
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.
Generally, you can resume normal activity the day after the procedure.
Your doctor may order this test if there are signs or symptoms of a problem with the aorta or its branches, including:
