The Venefit® (VNUS ClosureFast) RFA method is a minimally invasive therapy for varicose veins. You receive outpatient treatment under local anaesthetic; the risk of an infection is low. The damaged stem vein is treated with the help of a high-precision radiofrequency catheter. Only a small cut is necessary. Under ultrasound guidance the vein is heated up to about 120 degrees by high-frequency electric current radiofrequency and closed. After that it completely dissolves. Immediately after the operation sport is possible without any problems.
The endovenous laser ablation ELVT can be compared to radiofrequency therapy as far as the procedure is concerned. For the ELVT different lasers with wavelengths from 810 to 1470 nm are used. Average temperatures up to 700 degrees (Celsius) develop. Endonevous vapour ablation EVSA serves to close veins with the help of vapour. A catheter gives off hot vapour in two directions, the temperature of which may reach 120 degrees.
Like the treatment of spider veins Aethoxysklerol is injected into the varicose veins that need to be treated. But the veins are bigger so that a higher concentration is needed. Sclerotherapy only requires outpatient treatment and does not need any anaesthetization at all. As the success rate is rather low this method is only applied if none of the treatments described above is possible.
