Great Saphenous Vein. This vein is a conjunction of the dorsal vein of the great toe and the dorsal venous arch of the foot. It travels up the leg, in front of the inner ankle protruberance (anterior to the medial malleolus), and ascends all the way up the lower limb on the inner aspect leg and thigh (anteromedial aspect).
Measurements were carried out in 444 vein segments, (96 legs of 48 healthy volunteers, 52 legs of 35 patients with varicose veins). The common femoral vein (CVF), the femoral vein (FV) and the great saphenous vein (GSV) were investigated. The parameters of reflux and the relative venous diameter change (VD diff %) were measured simultaneously during a standardised Valsalva manoeuvre.
