Also, unlike ultrasonography of deep venous thrombosis, the procedure focuses mainly on superficial veins. Also, unlike the arterial ultrasound examination, blood velocity in veins has no diagnostic meaning. Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity.
The popliteal vein is a vein of the lower limb. It is formed from the anterior tibial vein and the posterior tibial vein. It travels medial to the popliteal artery, and becomes the femoral vein. It drains blood from the leg. It can be assessed using medical ultrasound. It can be affected by popliteal vein entrapment.
The tibial nerve, posterior tibial artery, posterior tibial vein, and flexor tendons travel in a bundle along this pathway through the tarsal tunnel, in the following order from anteromedial to posterolateral: Tibialis posterior tendon. [2] Flexor digitorum longus tendon. [2] Posterior tibial artery. [2] Posterior tibial vein. [1] Tibial nerve. [2]
The others lie at the sides of the popliteal vessels, and receive, as efferents, the trunks that accompany the anterior and posterior tibial vessels. [ 2 ] The efferents of the popliteal lymph nodes pass almost entirely alongside the femoral vessels to the deep inguinal lymph nodes , but a few may accompany the great saphenous vein , and end in ...
tibial nerve; common fibular nerve (also known as the common peroneal nerve) [3] popliteal vein; popliteal artery, a continuation of the femoral artery; small saphenous vein (termination) [3] Popliteal lymph nodes and vessels [3] It is of note that the common fibular nerve also begins at the superior angle of the popliteal fossa.

They drain the posterior compartment of the leg and the plantar surface of the foot to the popliteal vein, which it forms when it joins with the anterior tibial vein. [1] The posterior tibial vein is accompanied by an homonym artery, the posterior tibial artery, along its course. [2] It lies posterior to the medial malleolus in the ankle. [2]
The fibular veins are deep veins that help carry blood from the lateral compartment of the leg. They drain into the posterior tibial veins , which in turn drain into the popliteal vein . The fibular veins accompany the fibular artery .
Sometimes, the SSV joins the common gastrocnemius vein before draining in the popliteal vein. [2] Sometimes, it does not make contact with the popliteal vein, but goes up to drain in the GSV at a variable level. [1] Instead of draining in the popliteal vein, it can merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh.
