Stenting is a common treatment method used to expend arteries within the lower extremities affected by peripheral artery disease (PAD). This condition involves blockage, hardening or narrowing of blood vessels throughout the body as a result of a buildup of plaque. This reduced or blocked blood supply can significantly increase a person's risk of having a heart attack or stroke.
A stent is a wire mesh tube that can help keep affected arteries open once they have been expanded during a balloon angioplasty procedure. Stents are placed over a catheter that is then guided to the affected artery, where it will expand and remain in place after the catheter is removed. Over time, the inside lining of the artery will grow over the metal surface of the stent.
