During endovenous laser therapy (EVLT), a treatment for varicose veins, laser energy creates heat in a vein, which causes it to shrink and eventually disappear.
Varicose veins are a symptom of chronic venous insufficiency, which is common as people age. They are caused by a failure in the one-way valves that prevent blood from flowing backward into the legs. The resulting backflow, called reflux, and pooling of blood can lead to enlarged (varicose) veins. They are often visible through the skin of a person’s legs as reddish or blue in color, and can cause symptoms.
EVLT is performed on an outpatient basis.
EVLT is recommended to patients who:
- Have varicose veins that cause symptoms;
- Have circulatory problems because of chronic venous insufficiency;
- Cannot have surgery to treat varicose veins because of other conditions or vulnerabilities; or
- Wish to remove unsightly, enlarged veins.
