title: [Retrograde tibial approach for endovascular recanalization of popliteal and tibioperoneal artery occlusion].
abstract: OBJECTIVE
  To describe a procedure of the retrograde approach for endovascular treatment of complex popliteal and/or infrapopliteal occlusions and to determine its safety and efficacy in minimizing failure rates.
  
  
  METHODS
  Between January 2010 and March 2012, 28 patients (16 male and 12 female patients) received retrograde tibial approach after failure of antegrade intervention. There were 3 patients with severe claudication (Rutherford category 3) and 25 patients with critical limb ischemia (Rutherford category 4 to 6). From this group, two techniques were employed. Twenty-four patients were treated via a retrograde transpedal access site and 4 patients via a transcollateral loop technique. The clinical and follow-up data of these patients were analyzed retrospectively.
  
  
  RESULTS
  The technique success rates were 92.8% (26/28). No major complications and 3 (10.7%) minor sequelaes were documented in this study. Twenty-three patients were followed up for 3 to 29 months, with a mean of (14 ± 9) months. Overall patency was 73.9% (17/23) and 47.8% (11/23) at 6 and 12 months. Overall survival and limb salvage was 95.7% (22/23), ulcer were healed in 9/10 patients.
  
  
  CONCLUSIONS
  The use of retrograde tibial or pedal approach seems feasible and safety in case of failure in antegrade revascularization of popliteal and/or infrapopliteal occlusions.
