Venous diseases are common in the general population. After a comprehensive diagnostic evaluation, an individual therapeutic approach should be selected on the basis of the findings, with the aim of treating the diseased vein segments and improving quality of life. Numerous therapeutic options are available for the treatment of varicose veins. In addition to conservative methods such as compression therapy, exercise or drugs, surgical procedures such as traditional surgery, thermal ablation techniques or sclerotherapy can be performed. Recent developments include the use of endoluminal water vapor or mechano-chemical endovenous ablation.
