Micro-sclerotherapy

Sclerotherapy of small varicose veins is also called micro-sclerotherapy. It is an outpatient (ambulatory) method used to treat spider veins and reticular varicose veins without lasers, anaesthesia, or surgery. A specially developed medicinal product, the sclerosant, is injected directly into the diseased vein through a very fine needle. Inside the varicose vein, the sclerosant reacts with the vein wall. Normal processes in the body cause the walls to stick together, thus closing the vein so that blood no longer pools in the dilated vein. The body gradually converts the diseased vein into connective tissue and it disappears with time.

More than one treatment session may be needed, depending on the size and number of the varicose veins to be treated. Patients can resume their normal activities immediately after sclerotherapy and return to work without delay. Compression stockings should be worn for a few days after micro-sclerotherapy.
According to the German Society of Phlebology guidelines, sclerotherapy is the method of first choice for treating spider veins and small varicose veins.
