EVLT vs. Sclerotherapy — Which Vein Treatment Is Right for You?

EVLT (Endovenous Laser Treatment) is typically used for larger varicose veins and underlying venous insufficiency — the circulatory problem that causes varicose veins to form. Because it addresses a medical condition, it is often covered by insurance.

Sclerotherapy is typically used for spider veins and smaller surface vessels. It is a quicker procedure, but because it is generally considered cosmetic, it is usually self-pay.

If you are dealing with bulging, ropy veins with pain, swelling, or heaviness, EVLT may be the right path. If your concern is fine red or purple web-like veins near the skin surface, sclerotherapy is often the better fit. Patients across Manhattan, the Upper East Side, and Long Island regularly ask our team this exact question — and the answer always starts with a proper ultrasound evaluation.

EVLT stands for Endovenous Laser Treatment. It targets venous insufficiency, where faulty vein valves allow blood to pool and flow backward instead of returning efficiently to the heart.

During the procedure, a thin laser fiber is inserted into the affected vein through a small puncture. Under ultrasound guidance, heat energy closes the vein from the inside. Blood naturally reroutes through healthier veins as the treated vein is reabsorbed.

The procedure typically takes 45 to 60 minutes in-office under local anesthesia. Most patients in our Manhattan and Midtown locations return to normal activity the same day or the day after treatment.

Sclerotherapy treats spider veins and smaller superficial vessels by injecting a medical sclerosing solution directly into the vein. The vein wall collapses and gradually fades as the body clears it.

Most sessions take 15 to 30 minutes with little to no downtime. Patients at our spider vein treatment clinic usually return to normal daily activities right away.

Schulman Vein and Laser Center uses both traditional and foam sclerotherapy techniques based on vein size and treatment goals.

EVLT is typically best for larger refluxing varicose veins and symptomatic venous insufficiency. Sclerotherapy is best for spider veins and smaller surface vessels.

Both are minimally invasive, in-office treatments and can be combined in a staged plan when clinically appropriate — which is common for New York patients managing both symptomatic varicose veins and cosmetic spider veins.

Varicose veins are usually larger, raised, and associated with venous reflux symptoms such as heaviness, aching, and swelling. They signal a deeper circulation problem. Learn more on our varicose vein treatment page.

Spider veins are smaller surface vessels and are more commonly cosmetic, though they can occasionally cause mild burning or aching.

EVLT is frequently covered by insurance when medical necessity is documented through symptoms and ultrasound-confirmed venous insufficiency. Most New York carriers and Medicare require a trial of compression therapy before approving procedures.

Sclerotherapy is usually considered cosmetic and is typically self-pay unless unusual medical criteria are met.

Schulman Vein and Laser Center helps patients understand insurance requirements and handles prior authorization documentation before treatment is scheduled.

The right treatment depends on your vein anatomy, symptoms, and ultrasound findings. Choosing treatment before a proper evaluation can lead to recurrence or incomplete results.
