title: The bridge graft: a new concept for infrapopliteal surgery.
abstract: BACKGROUND
  The long-term results of ePTFE grafts are particularly poor in crural reconstructions. We report on a novel surgical technique, whereby both run-off and anastomotic mismatches are concomitantly addressed.
  
  
  METHODS
  Short segments of vein grafts (5-15 cm in length) were used to bridge two crural artery segments. Subsequently, a femoro-distal ePTFE graft was anastomosed to the bridge graft. Venous valves were made incompetent to allow bi-directional flow. In a retrospective series of 45 patients with crural bridge grafts, 12 patients were in stage III and 33 in stage IV. In 18 patients the reconstruction was the first procedure and in the remaining 28 patients it was the first or second re-operation.
  
  
  RESULTS
  The primary patency rate at 1, 2, 3 and 4 years was 53, 44, 35 and 26% respectively. The secondary patency rate was 67, 53, 49 and 39% respectively. The corresponding limb salvage rate was 70, 61, 56 and 45%. In a small subgroup of patients, in which the crural bridge was the first reconstructive procedure, the primary patency was 76 at 1 year and 64 at 4 years.
  
  
  CONCLUSIONS
  convincing long-term crural bridge grafts should be considered in those patients who have more than one crural or pedal artery available for grafting and an insufficient length of saphenous vein.
