Kurzbeschreibung/Zielsetzung

The treatment of varicose veins comprises conservative and active options. Every patient with varices has to be informed on the conservative modalities and should apply them in daily life. Compression therapy, as the most important part of the conservative treatment, should be considered individually for any patient according to the varicose-type, the grade of chronic venous insufficiency and the compliance of the patient. Active treatment modalities are clearly indicated in varices with complications such as trophic skin changes, varicophlebitis or when varices cause pain. But the cosmetic problem should not be underestimated. Morphologic and hemodynamic information obtained by noninvasive duplex technique allows the individualization of the surgical strategy for each patient. Besides surgical techniques used being less and less traumatic (invagination stripping, stab evulsion phlebectomy), more and more interventions are realized under ambulatory conditions in local anesthesia, even crossectomy with partial stripping of truncal varices. More important and complex operations, interventions involving more than one saphenous vein or reinterventions in recurrent varices are still performed under hospital conditions. They require only a short hospitalization time (2 to 4 days). Considering this very favourable evolution in surgery with a net trend to ambulatory, thus more economic treatment, the indications for sclerotherapy--a traditionally ambulatory modality with high recurrence-rate--are limited to reticular varices and telangiectasies.
