Answer

For complex cases, the following physiologic tests of venous function may reveal more information:

  • Venous refilling time (VRT) – Results correlate with severity of venous insufficiency and reflux

  • Maximum venous outflow (MVO) – Detects obstruction to venous outflow from the lower leg, regardless of cause

  • Calf muscle pump ejection fraction (MPEF) – Detects failure of the calf muscle pump to expel blood from the lower leg.

See Workup for more detail.
