Endothermal ablation is a minimal invasive procedure using heating energy to seal the affected varicose veins. For this purpose, two different methods which are radiofrequency ablation (RFA) and endovenous laser treatment (EVLT) are applied.
RFA and EVLT can be performed under local anesthesia or general anesthesia. RFA may temporarily cause paresthesia in a short time. EVLT may cause tightness in the legs, and nerve injury bruising and pain in the affected areas, but all of them are usually temporary side effects.
