An angiography, sometimes also referred to as an arteriography, is an exam which allows health care practitioners to see how well your blood is flowing through your arteries.

With your head held still, physicians will then insert a needle followed by a long narrow tube (catheter) into an artery near your groin area.

Once the imaging is complete, the catheter and needle will be removed from the body. You may be given a mild sedative before the procedure to relax your body or prevent discomfort. Once the procedure has finished and the groin area has been cleaned and bandaged, you should keep your legs straight for the next 4–6 hours and ensure no bleeding occurs.
