Endovenous laser ablation is a minimally invasive procedure used to treat varicose veins. A laser fiber is inserted into the affected vein, emitting heat that seals the vein shut. This redirects blood flow to healthier veins, reducing symptoms like pain and swelling, and improving the appearance of the legs. Dr. Arunagiri Viruthagiri, Consultant - Vascular & Endovascular Surgeon, discusses the use of endovenous laser ablation to treat varicose veins.
