Radiofrequency Ablation (RFA) and Endovenous Laser Therapy (EVLT) techniques are both “minimally invasive” procedures for the treatment of varicose veins. Both are relatively painless options and requires no hospitalisation. The difference between the two is primarily in the type of energy used , which is either thermal energy in the form of laser or radiofrequency energy to treat the diseased vein inside . The treated vein eventually is absorbed by the body. This causes decrease of venous pressure in the leg. Laser ablation may result in slightly more bruising after treatment but both options are relatively painless and require minimal recovery time. Radiofrequency ablation is used for treatment of incompetent saphenous veins and perforator veins, whereas laser ablation treats incompetent saphenous veins and is ideal for patients who have large , symptomatic varicose veins.
