How It Is Done continued...

An angiogram takes 1 to 3 hours. The catheter is taken out after the angiogram, and pressure is put on the needle site for 10 to 15 minutes to stop any bleeding. A small sandbag or clamp may be put on the site to hold pressure. A bandage is put on the site. You will be given pain medicine if you need it.

If the catheter was put in a vessel in your arm, you should not have any blood taken from that arm or your blood pressure measured in that arm for several days. You will rest in bed after the test for several hours. If the catheter was placed in the groin area, try to keep that leg straight for 8 hours. Your doctor will give you specific instructions after the test. You can use an ice pack on the needle site to relieve pain and swelling.

The place in your hands and feet where your heartbeat (peripheral pulse) can be felt may be marked with a pen. Your pulse may be checked before and after the angiogram.

How It Feels

You may feel a brief sting or pinch from the numbing medicine. Most people do not have pain when the catheter is in the blood vessel.

You may feel pressure in the blood vessel as the catheter is moved. Let your doctor know if you are having pain.

You will probably feel some warmth when the dye is put in. This feeling lasts only a few seconds. For some people, the feeling of heat is strong and for others it is very mild.

You may have a headache, flushing of the face, or a salty or metallic taste in your mouth after the dye is used. These feelings do not last long. Some people may feel sick to their stomachs or may vomit, but this is not common.

After the test, you may have some tenderness and bruising at the site where the catheter was inserted.

You can drink extra fluids to pass the dye from your body unless your doctor has told you not to.
