title: Evaluation of A-V impulse technology as a treatment for oedema following polytetrafluoroethylene femoropopliteal surgery in a randomised controlled trial.
abstract: OBJECTIVE
  To investigate the efficacy of A-V impulse technology (A-V) for oedema prevention and treatment following PTFE femoropopliteal surgery.
  
  
  METHODS
  Prospective randomized clinical trial.
  
  
  METHODS
  36 patients undergoing PTFE femoropopliteal bypass reconstructions, either being treated postoperatively with a compression stocking (CS) (Group-1, n = 19) or with A-V (Group-2, n = 17).
  
  
  METHODS
  Patients in treatment group-1 used a CS postoperatively during 1 week day and night, patients in group-2 were treated with A-V postoperatively at night during one week. The lower leg circumference was measured preoperatively and at five postoperative time points.
  
  
  RESULTS
  Limb circumference has increased postoperatively on day 1 (CS 1.5%/A-V 1.4%), on day 4 (5.7%/6.3%), on day 7 (6.6%/6.1%), on day 14 (7.9%/7.7%) and on day 90 (5.8%/5.2%). Differences between treatment groups were not significant. A re-operation gives a significant 3.9% increase in circumference as compared to a first operation (95% CI: 1.5-6.4%; p = 0.002).
  
  
  CONCLUSIONS
  No significant differences were found in the extent of developed edema between the groups following PTFE femoropopliteal bypass surgery. A redo peripheral bypass operation results in significantly more postoperative oedema than a first-time performed bypass operation.
