title: Efficacy of Viabahn in the treatment of severe superficial femoral artery lesions: which factors influence long-term patency?
abstract: OBJECTIVE
  To evaluate superficial femoral artery (SFA) occlusive disease treatment by means of covered stents.
  
  
  METHODS
  retrospective.
  
  
  METHODS
  From 2000 to 2005, a Hemobahn/Viabahn endoprosthesis was implanted in 102 limbs (95 patients; mean age: 72.1 years, 52-94) for intermittent claudication (group I, n=50 limbs), critical (group II, n=32) or acute ischemia (group III, n=20). Lesions treated were Trans-Atlantic Inter-Society Consensus (TASC) A (n=9) B (n=42), C (n=28) or D (n=23), associated with a good (2 or 3 leg arteries, n=60) or a poor (1 or 0 artery, n=42) runoff.
  
  
  RESULTS
  The endograft was placed successfully in all cases, but 3 early deaths (3.2%) (1 in group II and 2 in group III), and 4 acute thromboses (4%) occurred. Primary and secondary actuarial patency rates were 97+/-1.7%, and 99+/-1% at 1 month, 74+/-4.8% & 84+/-4.1% at 1 year,and 71+/-9.5% & 79+/-8.5% at 3 years, after a mean follow-up of 30.2 months (1-60). Long-term primary and secondary patencies were significantly different between TASC Cand TASC D lesions (P<.004 & .001).
  
  
  CONCLUSIONS
  Severity of lesions, rather than preoperative symptoms or runoff, is mainly to be considered before using Hemobahn/Viabahn endoprosthesis in severe SFA occlusive lesions.
