Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to your legs. Fatty deposits can build up inside the arteries and block blood flow.
Angioplasty uses a medical “balloon” to widen blocked arteries. The balloon presses against the inside wall of the artery to open the space and improve blood flow. A metal stent is often placed across the artery wall to keep the artery from narrowing again.

To treat a blockage in your leg, angioplasty can be done in the following:

• Aorta, the main artery that comes from your heart
• Artery in your hip or pelvis
• Artery in your thigh
• Artery behind your knee
• Artery in your lower leg
