What is Endovenous Laser Therapy? EVLT Explained.

Posted on February 27, 2017 by Dr. Stephen Rivard


Over the last decade treatment for varicose vein disease has made significant advancements. These advancements have improved efficacy rates and recovery time, reduced pain as a result of the procedure and allowed patients to seek treatment in the comfort of an out patient clinic setting. While there are a few very common procedures offered these days, one of the most popular forms of varicose vein treatment is known as Endovenous Laser Therapy (EVLT).

Many of the treatments focus around the same application of heat within the veins to seal the veins, however, Endovenous Laser Therapy uses a thin laser fiber to apply the heat. At the tip of the laser is where the heat is created and using a small catheter the laser fiber is placed inside the damaged vein - often guided with an ultrasound. While applying the appropriate amount of heat the laser fiber is gently removed as heat is applied. Think of a zipper, but reversed. This allows for the vein to seal as the laser is removed to close off the vein - which eventually dissolves into the blood stream.

Once the laser fiber is removed, the blood flow to that vein is redirected to healthy working veins, decreasing pressure and swelling almost immediately. EVLT is one of the most effective forms of modern day varicose vein treatment with efficacy rates as high as 98%. Other benefits from using EVLT treatments focus on treating your varicose veins at their source - meaning that these damaged veins will not return later in life.

EVLT is most commonly used for deep veins, and is one of the first forms of proper varicose vein treatment, followed by other treatments that focus on more surface veins - or branch veins. Think of a diseased tree, the varicose veins are the trunk, spider veins are the branches. EVLT helps to remove the trunk.
