Peripheral angiograms (arteriograms) are considered the gold standard for testing the arteries which supply the blood to the head and neck or those to the abdomen and legs. Peripheral angiograms do not include the brain or heart vessels. The type of treatment your particular condition may require will be determined by your angiogram. These are minimally invasive, outpatient procedures and usually you may go home after the procedure. When angiograms are performed during a surgical procedure, the length of time in the hospital will be individualized by your condition. Because these procedures involve the use of a contrast material to allow visualization of the blood vessels on an imaging screen, you may be prescribed medication to take before the procedure to protect the kidneys and will be asked to drink more water the day before the procedure.
