  1. Parameters were measured during the different phases of an operative cycle at baseline, after 30 minutes, and at the end of the treatment.
  2. Abbreviations: GP Gradient Pump device, SFC sequential foot-calf device, TAV Time Averaged Velocity, BF Blood Flow, FV Femoral Vein, PA Popliteal artery.
  3. For GP device: Cp, early (pushing) compression phase, and Cc, full (closing) compression phase; D, Decompression phase. For SFC device: C, Compression phase; D, Decompression phase.
  4. Data refer to 12 patients/20 diseased legs for GP device and 11 patients/18 diseased legs for SFC device.
