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.
