[TA]
formed by the union of the dorsal vein of the great toe and the dorsal venous arch of the foot, ascends anterior to the medial malleolus, posterior to the medial condyle of the femur, and traverses the saphenous hiatus in the fascia lata to empty into the femoral vein in the upper part of the femoral triangle.

long saphenous vein

The longest vein in the body, the long saphenous is the major superficial vein of the lower leg. It begins in the venous plexus along the medial side of the foot, and it runs up the medial side of the leg and knee, alongside the saphenous nerve. In the thigh, the long saphenous vein continues up the medial surface, accompanying the medial femoral cutaneous nerve. Before reaching the inguinal ligament, the long saphenous vein slips under the deep fascia of the thigh through a tunnel called the saphenous opening; the vein then empties into the underlying femoral vein. Tributaries of the long saphenous vein include the posterior tibial, posteromedial thigh, anterolateral thigh, superficial epigastric, superficial circumflex iliac, and external pudendal veins.
