title: Subintimal recanalization of femoropopliteal occlusive lesions in patients with critical ischemia: 66 cases.
abstract: BACKGROUND
  Subintimal recanalization allows for the treatment of percutaneously extended occlusive lesions. The aim of this study was to evaluate the feasibility and short- and mid-term results of subintimal recanalization in the treatment of femoropopliteal occlusive lesions in patients with critical ischemia.
  
  
  METHODS
  Between January 2009 and December 2010, consecutive patients with critical ischemia presenting with femoropopliteal arterial occlusion were included in this study. These patients underwent subintimal recanalization, and all patients had clinical and ultrasound follow-up.
  
  
  RESULTS
  Sixty-six procedures were performed on 66 patients (mean age, 79±10 yrs). All patients were American Society of Anesthesiologists classification 3 or 4. Thirty-two patients had diabetes and 27 had chronic renal insufficiency. More than two-thirds (76%) of the lesions had a Trans-Atlantic Inter-Society Classification of C or D. The mean occlusion length was 13.5±7 cm. The rate of technical success was 85%. The peroperative complication rate was 4.5%. There were no cases of operative mortality. Occlusion length was the only predictive factor of restenosis (P=0.049). At 1 year, primary and secondary patency rates were 56% and 70%, respectively, for a 92% rate of limb salvage.
  
  
  CONCLUSIONS
  The subintimal recanalization technique is feasible and minimally invasive. At 1 year postprocedure, the primary patency is poor, but this technique is associated with a high rate of limb salvage. It is suitable for the treatment of critical ischemia, taking into account the often precarious clinical backgrounds of these patients.
