The detailed process of an arteriogram procedure depends on the part of the body involved, according to Healthline. The procedure generally consists of the doctor inserting a tube in a vein that is guided to a specific area. Dye is injected through the tube to reveal blockages on an X-ray.
An anteriogram can be performed on the heart, kidneys, lungs and aorta, Healthline reports. It can also be used in the eyes, brain and extremities. The procedure creates an image of the arteries using dye and X-rays so that the doctor can observe flow through the arteries and identify any blockages or damage.
Most patients are offered a sedative during an anteriogram, Healthline says. The doctor inserts a catheter in an artery, usually in the leg, to administer the dye and sometimes to treat a blockage or constriction. They doctor guides the catheter to the area to be observed. Then dye is injected to flow through the surrounding arteries. The dye appears in an X-ray and can highlight any trouble spots. In some anteriograms, the doctor can use the catheter to treat damaged or blocked arteries.
Anteriograms can detect tumors, blood clots, hemorrhages, constricted vessels and inflammation, Healthline states. After the procedure, the doctor can determine the best treatment for the patient's condition.
