 Superficial venous system     Deep venous system

A: Superficial venous system

Main veins 1 Great saphenous vein (Vena saphena magna) 2 Small saphenous vein (Vena saphena parva)

Lateral tributaries 3 Superficial epigastric vein (Vena epigastrica superficialis) 4 Superficial circumflexiliac vein (Vena circumflexa iliaca superficialis) 5 Posterior accessory saphenous vein (Vena saphena accessoria posterior) 6 Anterior accessory saphenous vein (Vena saphena accessoria anterior) 7 External pudendal vein (Vena pudenda externa) 8 Posterior arcuate vein (Vena arcuata cruris posterior) 9 Anterior arcuate vein (Vena arcuata cruris anterior) 10 Posterior femoral vein (Vena Giacomini)

11 Saphenofemoral junction (“Magna-Krosse”) 12 Saphenopopliteal junction (“Parva-Krosse”)

14 Anterior tibial vein (Venae tibiales anteriores) 15 Posterior tibial vein (Venae tibiales posteriores) 16 Fibular vein (Venae fibulares) 17 Popliteal vein (Vena poplitea) 18 Femoral vein (Vena femoralis) 19 Deep femoral vein (Vena profunda femoris)

Function of the venous valves – in health

These clots can block the veins and prevent the venous return. The first signs of thrombosis are swelling of the calf, pain and a feeling of heaviness.

Function of the venous valves – in venous disease

A medical compression garment helps to approximate defective venous valves, thereby improving the venous return and lowering venous hypertension.

Irregular blood flow allows the formation of blood clots on the vessel wall.
