Covered stenting of the superficial femoral artery using the Viabahn stent-graft.

High initial technical success rates for superficial femoral artery revascularization are possible using multiple modalities. For these interventions to pose a serious challenge to open surgical bypass, improved primary patency in mid- and long-term follow-up must be achieved. In several smaller studies, covered stenting of the superficial femoral artery has shown superior patency at 2 years after intervention. The ongoing VIBRANT trial randomizes patients to superficial femoral artery intervention with either bare nitinol stents or Viabahn covered stents. The 3-year outcomes data from this trial will better define the role of percutaneous intervention for complex superficial femoral artery disease.
