Endovenous Laser Ablation (EVLA)
Aching, heavy legs and bulging varicose veins often start with a leaking vein you can’t see. Endovenous laser ablation (EVLA) uses laser heat to close that vein from the inside, so blood reroutes through healthier veins. It’s done in the clinic with local numbing, and most people walk out the same day. At MVM Health, a vein specialist checks your veins with ultrasound first to see whether EVLA is the right fit.

What Is Endovenous Laser Ablation?
“Endovenous” means inside the vein. During EVLA, a thin laser fiber is placed inside a leaking vein and used to seal it shut. The treatment is also called EVLT (endovenous laser treatment) or laser vein ablation, and it has been used to treat varicose veins for more than 20 years.
Healthy leg veins have one-way valves that keep blood moving up toward the heart. When the valves in a main surface vein stop working, blood leaks backward and pools in the lower leg. This is called venous reflux, and over time it can lead to varicose veins and chronic venous insufficiency. Closing the leaking vein lets blood return to the heart through healthier veins.
What Does EVLA Treat?
EVLA targets larger veins under the skin where reflux usually starts. Your specialist may recommend it for:
Saphenous Vein Reflux
Leaking valves in the great or small saphenous vein, the main surface veins of the leg, confirmed on ultrasound.
Bulging Varicose Veins
Rope-like veins that form when backed-up pressure from a leaking vein stretches smaller branches near the skin.
Heavy, Aching Legs
Legs that feel tired, heavy, achy or crampy by the end of the day, especially after long periods of standing.
Swelling and Skin Changes
Ankle swelling, darkening skin or hard patches near the ankle that can develop when vein pressure stays high.
Are You a Candidate for EVLA?
EVLA suits many adults with vein reflux, but your specialist decides after an exam and ultrasound. If several of these apply to you, an evaluation is worth it.
If you answered yes to several and you’ve noticed leg symptoms, a vein evaluation can tell you what’s going on.
EVLA may suit you if you have:
- Ultrasound-confirmed reflux in the great or small saphenous vein
- Aching, heavy legs, swelling, night cramps or skin changes near the ankle
- A vein segment straight enough for the laser fiber to pass through
- Symptoms that continue despite compression stockings or lifestyle changes
- A wish for a treatment with a quick return to routine
Talk to your provider first if you:
- Are pregnant or breastfeeding
- Have had a blood clot in a deep vein
- Take blood thinners or have a bleeding disorder
- Have very twisted vein sections
Benefits of Laser Ablation
No Surgical Cuts
EVLA is done through a single needle entry, so there are no incisions or stitches and scarring is minimal.
Local Numbing Only
You stay awake and comfortable with local anesthetic. There’s no general anesthesia and no hospital stay.
Quick Return to Routine
Most people walk right after treatment and return to work and light activity within one to two days.
Proven Over Time
Large reviews of clinical trials show laser ablation closes veins at least as well as vein stripping surgery.
When to Consider Laser Ablation
Book a vein evaluation if leg heaviness, aching, cramping or swelling keeps coming back, gets in the way of work, sleep or exercise, or if bulging veins are getting larger. Earlier treatment can help keep vein disease from progressing to skin changes or ulcers.
Get care right away if one leg suddenly becomes swollen, painful, warm or red, or if a vein bleeds and won’t stop. Call 911 for sudden shortness of breath or chest pain.

Before Your EVLA Treatment
Every EVLA treatment at MVM Health starts with a full evaluation, so your specialist can confirm the source of the problem first.
STEP 1 · YOUR VISIT
Your specialist reviews your symptoms and health history. Tell your care team about blood thinners, allergies, past clots and pregnancy.
STEP 2 · DUPLEX ULTRASOUND
A painless ultrasound maps your leg veins, shows which ones are leaking and checks whether the vein is straight enough for a laser fiber.
STEP 3. HOW TO PREPARE
Your specialist explains your options. Don’t stop any prescribed medicine unless told to. Wear loose clothing and bring compression stockings if prescribed.
EVLA vs. Vein Stripping and Other Options
Before endovenous treatments, faulty veins were usually tied off and pulled out through cuts in the skin, often under general anesthesia, and recovery could take weeks. EVLA closes the vein in place through a single needle entry, using local numbing.
A large Cochrane review of clinical trials found that laser ablation closed the treated vein at least as well as surgery, with similar rates of vein problems coming back over five years. EVLA and radiofrequency ablation both use heat and show similar long-term success. Your specialist picks the method that best fits your vein anatomy.
| Feature | EVLA | Vein Stripping | RFA | VenaSeal / ClariVein |
|---|---|---|---|---|
| How it works | Laser heat seals the vein inside | Vein tied off and pulled out | Radiofrequency heat seals the vein | Adhesive or spinning wire + medicine, no heat |
| Incisions | Single needle entry | Several cuts | Single needle entry | Single needle entry |
| Anesthesia | Local numbing along the vein | Often general | Local numbing along the vein | Usually one numbing shot |
| Setting | Outpatient | Often hospital | Outpatient | Outpatient |
| Return to routine | About 1–2 days | Often 1–3 weeks | About 1 day | Often same day |
| Long-term closure | Very high | High | Very high | High (VenaSeal) / good, more reopening (ClariVein) |

How Laser Ablation Works
EVLA is an outpatient procedure done through a single needle entry, so there are no large incisions or stitches. The laser treatment usually takes under an hour for each vein, and ultrasound is used throughout so your provider can see the vein and fiber at every step. In general, it follows four steps:
1
Map and Numb Ultrasound marks the leaking vein, then a small spot on the leg is numbed and a needle is placed into the vein.
2
Place the Laser Fiber A thin sheath is guided into the vein, and the laser fiber is passed through it to the treatment starting point.
3
Protect and Seal Numbing fluid is placed around the vein to protect nearby tissue. The laser is turned on as the fiber is slowly pulled back.
4
Blood Reroutes The sealed vein shrinks and closes. Over the following months, your body absorbs it and blood uses healthier veins.
Recovery After EVLA
Most people get back to normal life quickly. These steps help you heal comfortably:
Walk soon after treatment and several times a day, and avoid sitting or standing still for long periods.
Wear your bandage or compression stocking as directed, often for about a week, to ease swelling and soreness.
Skip heavy exercise, lifting, hot baths and long trips for a short time, or as your provider advises.
Keep your follow-up ultrasound, which confirms the vein has closed and the deep veins are clear.
Laser Ablation Myths, Answered
A few common beliefs keep people from getting help. Here’s what’s actually true:
MYTH
The laser burns the skin.
FACT
The laser works inside the vein, and numbing fluid around it acts as a protective layer, so skin burns are rare.
MYTH
Laser ablation removes spider veins.
FACT
EVLA treats larger leaking veins. Spider veins are treated with sclerotherapy, often after EVLA.
MYTH
Closing a vein hurts circulation.
FACT
The treated vein is already working poorly. Blood reroutes through healthy veins, which often improves flow.
MYTH
It's a new, untested treatment.
FACT
EVLA has been used for more than 20 years and is backed by large reviews of clinical trials.

EVLA Side Effects and Risks
Most side effects are mild and fade within a few weeks. An experienced vein specialist and careful ultrasound guidance help keep risks low.
Call 911 for sudden shortness of breath or chest pain. Contact your care team the same day for new calf swelling, pain or warmth.
More common, temporary:
- Bruising, soreness or tightness along the treated vein
- A firm, cord-like feeling under the skin
- Temporary numbness or tingling from a nearby nerve
- Inflammation of a surface vein (phlebitis)
Less common:
- Skin burn (rare, thanks to the protective numbing fluid)
- Infection at the entry site (rare)
- Blood clot in a deep vein (rare)
- A clot traveling to the lungs (very rare)

Frequently Asked Questions
Most people feel a sting from the numbing injections, then only pressure or warmth during treatment. Soreness or tightness afterward usually eases within one to two weeks.
The laser treatment usually takes under an hour for each vein. Plan for a longer visit to allow for check-in, ultrasound mapping, numbing and a short rest.
Most people return to work and light activity within one to two days. Bruising and tightness fade over one to two weeks, and leg symptoms often improve over the following weeks.
The laser works inside the vein, not on the skin surface. Numbing fluid placed around the vein acts as a protective layer, so skin burns are rare.
No. EVLA is designed for larger veins that leak blood backward. Spider veins are usually treated with sclerotherapy instead.
Both use heat to close the vein from the inside, and studies show similar success over time. Your provider chooses based on your vein anatomy, the equipment available and your comfort.
Most people can, since only local numbing is used. If you’re given medicine to help you relax, you’ll need someone else to drive.
Many bulging veins shrink once the leaking vein feeding them is closed. Those that remain visible can be treated with sclerotherapy or phlebectomy.
Many plans cover it when it’s medically necessary, based on your symptoms and ultrasound findings. Some require prior authorization or a compression trial first. Our team checks your benefits.
A vein closed with EVLA rarely reopens. New varicose veins can still form over time, especially with a family history, pregnancy, extra weight or long hours on your feet. Staying active and having follow-up visits help catch any new problem veins early, when they’re easier to treat.
