• Temperature: warm (DVT, infection)
  • Tense and tender calf (DVT)
  • Homan’s sign- stretching calf by foot dorsiflexion causes pain
  • Pitting edema
  • Skin thickening, redness
  • Cord like superficial tender swelling (superficial thrombophlebitis)

Tapping the venous column
demonstrates pressure transmission to incompetent distal veins.

Coughing impulse at sapheno-femoral junction denotes incompetent valve

Trendelenburg test

  • Patient’s leg elevated to drain venous blood.
  • An elastic tourniquet applied at the sapheno-femoral junction
  • The patient then stands with tourniquet in place.
  • Rapid filling (<30 seconds) of the great saphenous system- perforator valve incompetent.
  • No filling - perforators are competent
  • Now release the tourniquet
  • Filling of the great saphenous system from above- sapheno-femoral valve is also incompetent.
