[Treatment of primary varicosis].

While the treatment of varicose veins has remained unchanged over the past 100 years based on the three principles of compression, sclerotherapy, and classic varicose vein surgery, alternative approaches and advancements in treatment have developed in the last 10 years such as foam sclerotherapy, endovenous laser therapy, and radiofrequency obliteration. In contrast to classic varicose vein surgery, prospective, randomized, comparative studies are available with respect to the modern treatment procedures. They clearly show that endovenous thermal techniques are not inferior to the classic operation regarding the perioperative complication rate. There appears to be a tendency toward considerably fewer perioperative complaints with endovenous laser therapy and in particular with radiofrequency obliteration. Foam sclerotherapy represents a minimally invasive alternative that is markedly cost-effective. Even though the occlusion rate of the root veins after foam sclerotherapy is not as good as after endovenous therapy, the method is initially very effective. Especially in cases of recurrent varicose veins from the saphenofemoral or popliteal junction, foam sclerotherapy should be considered as the ideal method. All procedures significantly improve the patients' quality of life and the symptom complaints related to varicose veins. They are not in competition, but rather partially complement each other so that a combination of several approaches is quite judicious.
