title: Treatment of complex atherosclerotic femoropopliteal artery disease with a self-expanding interwoven nitinol stent: Midterm results.
abstract: OBJECTIVE
  To examine the efficacy and durability of an interwoven self-expanding nitinol stent for the treatment of superficial femoral and popliteal arteries.
  
  
  METHODS
  Consecutive patients with severely diseased superficial femoral and popliteal arteries who received SUPERA® stents were retrospectively identified.The patients were followed for 12 months by Doppler ultrasound examinations, stent roentgenograms, and estimation of Rutherford-Becker class and ankle-brachial index.
  
  
  RESULTS
  From July 2012 to May 2014, 42 limbs in 36 patients (mean age, 61.5 ± 7.5 years; 75% male) were treated with angioplasty and primary stenting. Total occlusions were present in 14 limbs, and 63.8% had either moderate or severe calcification. The mean (±SD) lesion length was 105 mm (±28). Primary patency was 91.4% at 6 months and 85.7% at 12 months. The ankle brachial index increased from 0.57 ± 0.19 preoperative to 0.91 ± 0.12 postoperative. There was no procedural or device-related morbidity or mortality after revascularization and only one major amputation was observed on follow-up.
  
  
  CONCLUSIONS
  Our experience shows that, Supera stents are safe and effective in our cohort of patients, with acceptable patency rates. There were no stent fractures so far even with stenting of the femoropopliteal segments. Stent design provides a viable option for high-grade obstructive disease in the femoropopliteal artery.
