saphenous veins

; SV main superficial veins draining the leg and foot
  • great SV; long SV largest of the two main superficial veins in lower leg; extends from medial dorsal foot to the proximal thigh; drains medial aspect of foot, lower limb and thigh; formed by union of the medial end of dorsal venous arch and medial dorsal digital vein; courses proximally via anterior aspect of medial malleolus into the lower limb at anteromedial aspect of lower one-third of tibia; passes to posteromedial aspect of knee and via saphenous opening to anteromedial thigh, becoming continuous with (deep) femoral vein; it is compartmented along its entire length by a system of valves; gives rise to several communicating veins linking with deep-vein system, e.g. medial plantar veins, anterior tibial vein anterior to ankle and tributaries of posterior tibial vein

  • small SV; short SV shorter of the two main superficial veins in lower leg; extends from lateral dorsal foot to knee; formed by union of the lateral end of dorsal venous arch and lateral dorsal digital vein; courses proximally via inferior/posterior aspect of lateral malleolus; ascends along midline of lower leg; pierces deep fascia at lower border of popliteal fossa to enter popliteal vein of deep-vein system; drains lateral side of foot and ankle and posterior area of lower leg; anastomoses with tributaries of great SV
