Angiogram of the Head and Neck

How To Prepare continued...

Do not eat or drink for 4 to 8 hours before the angiogram. You may be asked to not take aspirin, aspirin products, or blood thinners for several days before the test and for 1 day after the test. If you take these medicines, talk with your doctor.

An angiogram can be done as an inpatient or outpatient. If you are an outpatient, you will stay in a recovery room for several hours before you go home. You may want to bring something to do or read to pass the time. Arrange to have someone take you home because you may get a sedative before the test. If you stay overnight in the hospital, you will likely go home the next day.

The test may take several hours, so you will empty your bladder just before it begins.

Also before the angiogram you may have other blood tests, such as blood clotting (coagulation) studies, blood urea nitrogen (BUN), and creatinine.

You will be asked to sign a consent form that says you understand the risks of the test and agree to have it done.

Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).

How It Is Done

An angiogram camera.gif can be done by different types of doctors, including a radiologist, cardiologist, or surgeon. Your doctor may be helped by a radiology technologist or a nurse.

You will need to take off any jewelry. You may need to take off all or most of your clothes. You will be given a gown to wear during the test.

During the test

You will likely have an intravenous (IV) line in a vein in your arm so your doctor can give you medicine or fluids if needed. A device called a pulse oximeter, which measures oxygen levels in your blood, may be clipped to your finger or ear. Small discs (electrodes) are placed on your arms, chest, or legs to record your heart rate and rhythm.

You will lie on your back on an X-ray table. Ask for a pad or blanket to make yourself comfortable. A strap, tape, or sandbags may be used to hold your body still. A lead apron may be placed under your genital and pelvic areas to protect them from X-ray exposure.

A round cylinder or rectangular box that takes the pictures during fluoroscopy will be moved above you. The fluoroscope will move under you during the test.

The place where the catheter will be inserted (in the groin or above the elbow) will be shaved and cleaned. Your doctor will numb the area with a local anesthetic. Then he or she will put a needle into the blood vessel. A guide wire will be put through the needle into the blood vessel and the needle will be removed. The catheter then will be placed over the guide wire and moved into the blood vessel. The catheter will be guided through the blood vessels until the tip is in the area to be studied. Your doctor will use the fluoroscope to watch the movement of the catheter in the blood vessels.
