The Posterior Tibial Vein is a significant vein located in the lower leg, responsible for draining blood from the posterior compartment of the leg and the plantar surface of the foot. It is a paired vein, with one running along each leg.

Structure

The posterior tibial vein originates from the Plantar venous arch and ascends along the medial side of the leg, running parallel to the Posterior tibial artery. It is accompanied along its course by the posterior tibial artery and its corresponding nerves.

Function

The primary function of the posterior tibial vein is to return deoxygenated blood from the lower leg and foot back to the heart. It does this by merging with the Peroneal vein to form the Tibial veins, which in turn join to form the Popliteal vein.

Clinical significance

Due to its location and function, the posterior tibial vein can be involved in several medical conditions, including Deep vein thrombosis and Varicose veins. Its accessibility makes it a common site for venous access in certain medical procedures.
