Endovenous Thermal Ablation Treatment

Feeling and looking healthy, sooner.


Endovenous Thermal Ablation Treatment 101

Endovenous Thermal Ablation Treatment, also known as laser therapy, is a safe, proven medical procedure that not only treats the symptoms of varicose veins, but also treats the underlying condition that causes them. The outpatient procedure time is usually less than an hour and does not require hospitalization. Most people do not find endovenous thermal ablation to be overly uncomfortable, and recovery time is generally a matter of hours.

In EVTA (sometimes referred to as “laser treatment”), the doctor uses a small optic fiber inserted directly into targeted veins, and laser light is delivered to heat and collapse veins with unhealthy valves. The procedure is nearly always performed under ultrasound guidance, giving the doctor a live view of your veins, for accuracy and safety. Watch the video below on how EVLT laser therapy treats varicose veins.


This minimally-invasive outpatient procedure, which takes less than an 45 minutes to perform, uses laser light to shrink and close varicose veins. The laser is inserted into the target veins through a catheter, leaving surrounding tissues unaffected.


In preparation for the treatment, the physician uses a hand-held ultrasound probe to scan the varicose veins through the skin. The ultrasound allows the physician to visualize the anatomy of the veins and identify weak valves or other trouble spots that are causing the problem.

Inserting the Instruments

After cleaning and sterilizing the skin, the physician inserts a tiny guide wire through the skin and into the target vein. Once inside, a sheath is inserted along the wire and fed up through the varicose vein. When the sheath is in place, the laser is placed inside and gently fed into the vein.

Treating the Vein

After local anesthetic is injected through the skin to numb the vein, the laser is activated and slowly pulled back through the vein. The laser heats the vein walls, causing the tissue to contract and the vein to close. The lasing process typically lasts no more than two or three minutes.

End of Procedure

Relief of symptoms may be immediate. The patient will wear a compression stocking for up to two weeks following the procedure. In some cases, EVLT may be combined with other treatments to obtain the desired cosmetic outcome.


Healthy blood flow restored for improved circulation.

Endovenous thermal ablation treats varicose veins by destroying veins with damaged valves; they are eventually absorbed by your body. After laser treatment, blood flow is diverted to healthy veins, improving circulation.

Real Patients, Real Results

Not only has the pain in the back of my knees disappeared, but my thighs and calves now look fabulous. Haven't seen this clear skin look in more than 20 years. I can now spend time in the garden, cleaning the floors, and playing with my fur babies on the floor without any pain.


Every patient is unique, and so is every treatment plan.

EVTA, or laser treatment, cannot treat veins that are too small, twisted, and/or close to the surface of the skin; that’s what sclerotherapy is for. Your VCA vascular specialist will tailor a treatment plan specifically for your condition; it may involve a combination of different treatments to give you the best possible results. The goal is to improve your health and restore your active lifestyle as quickly as possible.
