Angiography

An angiogram is a procedure that is used to visualize the blood vessels (arteries), detect problems with functioning of the arteries and veins, and also provide treatment for various conditions.  

During the procedure, a contrast agent is injected into the blood vessel through the angiography catheter under local anesthesia.  Most commonly, the area used for the catheter insertion is the top of a leg where the femoral artery and femoral vein are located.
