Study details

  • Retrospective, non-randomized, multi-center study
  • All patients had CLI
  • Combined fem-pop and infrapopliteal limb salvage rate at 3 years was 81% in these CLI patients

…the good results at 3 years in primary interventions in patients with more than one distal vessel and with rest pain could suggest a significant role of the heparin-bonded graft in these subgroups of patients. — R. Pulli

Primary and secondary patency rates make this graft an excellent alternative to autologous saphenous vein when it is absent, unsuitable, or of poor quality. — R. Pulli
