Leg stenting, also called “angioplasty,” is a procedure designed to prop open arteries that have become blocked by fatty deposits. Any artery can be stented, but stents are most frequently used in the legs. Stents are very small and are made of wire mesh. To insert a stent, your surgeon will attach it to a balloon catheter via a small incision. Once the stent is in the correct place, your surgeon will expand and retract the balloon, propping open your artery and causing improved blood flow. While all surgeries carry some risks, stenting is considered a very safe procedure.
