PTA vs. Primary Stenting of SFA Using Self-Expandable Nitinol Stents
Balloon Angioplasty vs. Primary Stenting of Femoropopliteal Arteries Using Self-Expandable Nitinol Stents - a Randomized Controlled Trial
The investigators evaluated whether primary implantation of a self-expanding nitinol stent yielded anatomical and clinical benefits superior to those afforded by percutaneous transluminal angioplasty with optional secondary stenting.

Phase 4
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Peripheral Vascular Diseases
  • Intermittent Claudication
  • Angioplasty
  • Device: Nitinol stent
    Interventions are performed percutaneously from either an antegrade or an over-the-bifurcation approach. After insertion of an 6 French sheath, 5000 IU of heparin are administered intra-arterially. After passage of the stenosis/occlusion with the guide wire, patients are randomized to either PTA or primary stent implantation. For standardized documentation of the lesion morphology and comparability during follow-up, a ruler is fixed at the patients thigh with the distal end exactly overlapping at the upper edge of the patella. As a bail-out procedure in the PTA group, stent placement is performed in cases with a residual stenosis of more than 30% in the worst view angiogram.
