Laird, J. R. (n.d.). Limitations of Percutaneous Transluminal Angioplasty and
     Stenting for the Treatment of Diesease of the Superficial Femoral and
     Popliteal Arteries.
       Reflecting on the failing long-term patency rates of percutaneous
       angioplasty and stenting, this study aimed to asses long term data
       surrounding new nitinol stents which show promise so far on a short term
       basis. Balancing their success with high fracture rates, this study also
       asses the best conditions under which new nitinol stents may be
       prescribed for implantation, highlighting those patients who depict good
       distal runoff.
