A Novel Self-Expanding Interwoven Nitinol Stent for Complex Femoropopliteal Lesions: 24-Month Results of the SUPERA SFA Registry

Abstract

Purpose To examine the efficacy and integrity of a novel interwoven self-expanding nitinol stent system for the treatment of complex femoropopliteal lesions in a “real world” medical practice. Methods This retrospective analysis included 107 consecutive patients (77 men; mean age 68.9 years) with atherosclerotic femoropopliteal lesions (occlusions in 31%) who underwent implantation of 137 SUPERA stents. The patients were followed for up to 24 months by Doppler ultrasound examinations, radiography of the stent, and assessments of Rutherford-Becker class and ankle-brachial index (ABI). Results The mean implanted stent length was 111±50 mm (range 40–270). Procedure success (residual stenosis Conclusion Over a 2-year surveillance period, excellent durability without stent fractures was documented after implantation of the SUPERA stent in complex femoropopliteal lesions. In addition, significant improvements were observed in symptom classification and hemodynamics.
