  Purpose

This is a Belgian prospective multicentre registry to evaluate safety and performance of the Sinus-Superflex-Visual stent (Optimed) in Superficial Femoral Artery (SFA) atherosclerotic lesions. Target number is 500 patients in approximately 11 centres. Patients will be followed for a period of 2 years.


Condition
Peripheral Arterial Disease

Primary Outcome Measures:
  • Primary patency [ Time Frame: 12, 24 months ] [ Designated as safety issue: No ]
    Primary patency rate at 12 and 24 months as determined by Duplex ultrasound, defined as <50% diameter restenosis(systolic velocity ratio no greater than 2.4) at the level of the treated lesion, without occurrence of target lesion revasularization between the index-procedure and the 12 and 24 months follow-up.


Secondary Outcome Measures:
  • Secondary patency [ Time Frame: 12 and 24 months ] [ Designated as safety issue: No ]
    Patency as defined by absence of >50% restenosis , whether or not after additional intervention to maintain this patency

  • Target lesion revascularization [ Time Frame: 12 and 24 months ] [ Designated as safety issue: No ]
    Target lesion revascularisation rate as defined by the number of new revascularizations (endovascular or surgery) carried out due to restenosis or thrombosis at the level of the stented lesion

  • Target vessel revascularization [ Time Frame: 12 and 24 months ] [ Designated as safety issue: No ]
    Target vessel revascularization rate as defined by the number of new revascularizations (endovascular or surgery) carried out due to restenosis or a new stenosis in the SFA

  • Limb-salvage rate [ Time Frame: 12 and 24 months ] [ Designated as safety issue: No ]
  • Clinical success rate [ Time Frame: 12 and 24 months ] [ Designated as safety issue: No ]
    Clinical success rate defined asimprovement in symptoms according to the Rutherford classification by a minimum of 1 class.
