title: Fracture of a Supera Interwoven Nitinol Stent After Treatment of Popliteal Artery Stenosis.
abstract: To present a Supera stent fracture following treatment of popliteal artery stenosis.
  
  
  
  A 60-year-old man previously treated with angioplasty/stenting of a popliteal artery lesion with a Supera stent presented at 8 months with in-stent occlusion that proved to be secondary to stent fracture.
  
  
  
  Supera interwoven nitinol stents, despite having higher radial force and conformability than classic tube stents, are not free from fracture. Moreover, due to their peculiar structure, a break in these stents results in complete loss of integrity and consequent device collapse, thus jeopardizing endovascular recanalization and relining.
