title: Impact of different patency criteria on long-term results of femoropopliteal angioplasty: analysis of 106 consecutive patients with claudication.
abstract: OBJECTIVE
  To assess the impact of different patency criteria on long-term results after percutaneous transluminal angioplasty (PTA) of femoropopliteal arteries.
  
  
  METHODS
  The results of femoropopliteal PTA in 106 consecutive patients with claudication (140 treated limbs) were analyzed. The treated artery segment was considered patent if (a) the ankle-brachial index (ABI) had increased by more than 0.10 initially and not deteriorated by more than 0.15 from the maximum early postprocedural level and (b) the ABI was consistently at least 0.15 above the preprocedural level. The third criteria was based on patients' subjective assessment of patency. Initial failures were either included or excluded and both primary (the outcome of the original PTA) and secondary patency (also repeated PTAs included) were determined.
  
  
  RESULTS
  When the different criteria were applied, the patency rates at 3 years ranged from 42% to 82% in this patient population.
  
  
  CONCLUSIONS
  These results stress the importance of uniform criteria when results of different kind of vascular interventions are reported.
