Femoral vein

The femoral vein (Latin: vena femoralis) is a large blood vessel of the thigh formed by the popliteal vein and accompanying the femoral artery. The femoral vein collects deoxygenated blood from the muscles and skin of the thigh.

The femoral vein arises at the adductor canal as the continuation of the popliteal vein. It accompanies the femoral artery in the femoral sheath. The vein ends at the inferior margin of the inguinal ligament, becoming the external iliac vein. The main tributaries of the femoral vein, besides the popliteal vein, are the deep vein of the thigh and the great saphenous vein.
