Also known as the Large, Internal, or Long Saphenous, the Great Saphenous is a
superficial vein that runs from the foot to the upper thigh.
The Great Saphenous Vein begins
with the merging of the Dorsal Venous Arch and the Dorsal Vein of the
big toe. It travels up the medial side of the leg,
anastomosing with the Small Saphenous Vein. It is
connected to several smaller veins, including the anterior and
posterior tibials (located in the shins). At its distal end (the end
closest to the groin) it is joined by the superficial epigastic, the
superficial iliac circumflex, and the superficial external pudendal
vein. This allows it to drain blood from the lower abdominal wall,
upper thigh, and groin. It passes
through the fossa ovalis, or the saphenous opening, in the fascia lata
(a large muscle in the upper thigh) and empties into the Femoral Vein. This occurs
before the inguinal or Poupart's ligament. It is
the longest vein in the body.
There is some question about the origin of the term Saphenous.
Some believe it is from the Greek "Safaina", or "manifest", owing
to its superficial nature along its lower course. However, the
anatomist Avicenna referred to the vein as "al-Safin", Arabic for
"The Concealed". When the Great Saphenous travels up the thigh it is
"concealed" in its own fascial compartment.
