Endovenous laser therapy (EVLT) is a minimally invasive procedure used to treat varicose veins. It involves inserting a thin laser fiber into the affected vein through a small incision. The laser emits energy that heats the vein, causing it to collapse and seal shut, which redirects blood flow to healthier veins. This treatment is typically performed under local anesthesia and can be done in an outpatient setting. Patients may experience less pain and quicker recovery times compared to traditional surgical methods. EVLT is considered effective for improving symptoms and the appearance of varicose veins.
