Infrainguinal angioplasty has less initial and long-term success compared with more proximal sites. These suboptimal initial technical results may be related to the heavy calcific burden in the femoral and popliteal arteries and, subsequently, higher incidence of distal dissection. Cutting balloon angioplasty (CBA) is a newer technique that is thought ...
