Gastrocneimus Vein
Veins in the posterior calf associated with the gastrocnemius muscle. Clots can occur in these veins but, are not as dangerous as clots in the popliteal vein.
  -- Short-term natural history of isolated gastrocnemius and soleal vein thrombosis


Partibial Perforator
Also known as Boyd's and Sherman's perforators. These veins connect the saphenous vein to either the posterior tibial vein or the popliteal vein. -- Also called: Boyd's perforators, Sherman's perforators


Popliteal Vein
Refers to the main draining vein of the leg located behind the knee. The popliteal vein becomes the femoral vein in the lower thigh.


Small Saphenous Vein
(SSV) The small saphenous vein is located in the back of the leg. The vein starts at the crease in the knee and runs down the back of the calf and angles to the outside of the foot. This vein is responsible for varicose veins in 10% of patients. Varicose veins are located on the back of the calf or thigh. The vein empties into a deep vein called 'popliteal'. The popliteal vein is the main deep vein in the knee area. -- Also called: Short Saphenous Vein, Lesser Saphenous Vein
