title: Short-term results of a randomized trial comparing remote endarterectomy and supragenicular bypass surgery for long occlusions of the superficial femoral artery [the REVAS trial].
abstract: OBJECTIVE
  Techniques for surgical repair of Trans-Atlantic Inter-Society Consensus (TASC) C and D lesions of the superficial femoral artery (SFA) are supragenicular bypass grafting or the less invasive remote endarterectomy (RSFAE). This trial compares the patency rates of both techniques.
  
  
  METHODS
  Randomized, multicenter trial.
  
  
  METHODS
  116 patients were randomized to RSFAE (n=61) and supragenicular bypass surgery (n=55). Indications for surgery were claudication (n=77), rest pain (n=21), or tissue loss (n=18).
  
  
  RESULTS
  Median hospital stay was 4 days in the RSFAE group compared with 6 days in the bypass group (p=0.004). Primary patency after 1-year follow-up was 61% for RSFAE and 73% for bypass (p=0.094). Secondary patency was 79% for both groups. Subdividing between venous (n=25) and prosthetic grafts (n=30) shows a primary patency of 89% and 63% respectively at 1-year follow-up (p=0.086).
  
  
  CONCLUSIONS
  RSFAE is a minimally invasive adjunct in the treatment of TASC C and D lesions of the SFA, with shorter admittance and a comparable secondary patency rate to bypass. The venous bypass is superior to both RSFAE and PTFE bypass surgery, but only 45% of patients had a sufficient saphenous vein available. This study is registered with ClinicalTrials.gov, number NCT00566436.
