title: Present status of infrainguinal arterial bypass procedures following an all autogenous policy--long-term results of a single center.
abstract: OBJECTIVE
  The direction of vein grafts for infrainguinal arterial reconstruction is controversial. Long-term results of a single center following an all autogenous tissue policy in infrainguinal arterial reconstruction are reported with special attention to possible advantages for the in situ and non-reversed bypass using angioscopy.
  
  
  METHODS
  From 10/88 until 12/00 540 bypasses with autogenous veins were performed on 497 patients. Veins were used in a non-reversed or in-situ direction, valve disruption was performed under angioscopic control. All grafts were prospectively included in our data base and follow-up was scheduled in our vascular lab before discharge and after 3, 6, 9, 12, 24 etc. months.
  
  
  RESULTS
  Primary patency of all bypasses after 108 months was 55.2%, primary assisted 76.9% (SE +/- 9.87), survival 58.4% (SE +/- 8.88) and limb salvage 81.3% (SE +/- 9.75). Perioperative mortality was 0.9% (5 pat). Patency rates (primary assisted patency) after 72 months were 81.7% (98.2%) for supragenicular, 61.5% (79.4%) for infragenicular and 56.6% (78.1%) for tibial anastomoses and for pedal reconstructions after 48 months 49.3% (68.6%).
  
  
  CONCLUSIONS
  Reviewing the literature neither the in situ and non-reversed nor the reversed grafts yielded better long-term results. Absence of size mismatch may be an advantage in smaller veins. Angioscopy may detect unsuspected vein disease.
