Compression therapy is one of the most important methods in the treatment of venous disorders. Applying compression bandages or wearing compression stockings presses the distended veins (varicose veins, varicosities) together from the outside. This enables the venous valves to close again, the leg muscles can squeeze the blood better out of the veins which, in turn, improves the return transport of blood to the heart.
Since veins that have once been distended are no longer able to actively contract, such compression must be used for the rest of the patient’s life if surgery is contraindicated. However, even in cases where surgery is indicated, compression stockings must also be worn or the legs must be dressed with compressive bandages for a number of weeks after the surgical removal of the veins.
