Posterior tibial vein

The posterior tibial vein (latin: vena tibialis posterior) is a deep vein of the lower leg formed by the lateral and medial plantar arteries.

The posterior tibial vein arises on the plantar surface, ascends to the flexor retinaculum, then passes through the cruropopliteal canal, and at the distal border of the popliteus muscle the posterior tibial vein unites with the anterior tibial vein to form the popliteal vein.

Along its course the posterior tibial vein is accompanied by the posterior tibial artery.

The main tributaries of the posterior tibial vein are the medial and lateral plantar vein, the fibular veins and the superficial veins.

The posterior tibial vein collects venous blood from the posterior compartment of the leg and from the plantar surface of the foot.
