Radio Frequency Ablation (RFA) is a minimally invasive procedure adopted to treat varicose veins. This procedure is performed to avoid pain and follow nonsurgical technique with application of radiofrequency energy for generating heat. The heat is sent into the vein through a thin, flexible tube (catheter). This closes off blood flow in the main problem vein.
Effectiveness of RFA and its applications
RFA is a very effective procedure for targeted treatment towards specific abnormal tissue, with relatively low risk of complications such as bleeding, infection and damage to nearby tissue or organ. RFA has got applications especially for treating varicose veins, shrinking of benign thyroid nodules, and certain cases of endometriosis with difficult location-to-reach areas.
