2 Fig 1 A, The re-entry perforating vein (PV) would have a retrograde flow (red arrows) in muscular contraction (systole; orange arrows) which would ascend through the superficial venous tract. B, But during the muscular release (diastole; orange arrows), the lower pressure generated in the deep venous system would add to the hydrostatic pressure of the blood column from the superficial venous tract, thereby generating an anterograde flow which would be greater than the initial retrograde flow (blue arrows). C, Duplex examination of the PV during Paranà maneuver.13 : retained flow. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2009 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 A, Perforating veins (PV) acting as venous reflux points are those showing retrograde flow (red arrows) during muscular contraction (systole; orange arrows) (B) and principally during muscular release (diastole; orange arrows). C, Duplex examination of the PV during Paranà maneuver.13 VVs, Varicose veins; : retained flow.

4 Fig 3 A, Perforating veins (PV) acting as venous reflux points are those showing retrograde flow (red arrows) during muscular contraction (systole; orange arrows), (B) which would be markedly greater than the anterograde flow (blue arrows) during muscular release (diastole; orange arrows). C, Duplex examination of the PV during Paranà maneuver.13 VVs, Varicose veins; : retained flow.
