Procedures for peripheral artery disease (PAD)
Angiography uses a catheter, X-ray imaging guidance and an injection of contrast material to examine blood vessels in key areas of the body for abnormalities such as aneurysms and disease such as atherosclerosis (plaque). The use of a catheter makes it possible to combine diagnosis and treatment in a single procedure. Angiography produces very detailed, clear and accurate pictures of the blood vessels and may eliminate the need for surgery.
- The narrowing in the artery may be reduced, resulting in improved blood flow.
- The risk of complications are rare.
- You may be able to return to normal activities shortly after the procedure.
- The procedure is usually performed using local anesthesia, which involves fewer risks than general anesthesia.
Balloon angioplasty is a minimally invasive, non-surgical endovascular procedure to widen narrowed or obstructed arteries or veins caused by plaque buildup in the vessels. During the procedure, the doctor injects contrast through a small, thin tube called a catheter into your bloodstream. The contrast allows the doctor to view your blood vessels on an X-ray monitor. A catheter with a small balloon on its tip is then inserted through an artery in your leg or arm and threaded through the arteries until it reaches the narrowed area. The balloon is inflated to flatten the plaque against the wall of the artery, opening the artery and restoring blood flow. Then the balloon is deflated and removed from your body. This allows more blood and oxygen to be delivered to the leg and feet.
