Endovenous Laser Ablation, commonly called EVLA or EVLT, is a modern, minimally invasive treatment for varicose veins. It uses laser energy to close off damaged veins in the legs, allowing blood to flow through healthier veins instead. This procedure has largely replaced traditional vein surgery for many patients because it is less painful, requires no large incisions, and allows faster recovery.
Varicose veins are swollen, twisted veins that can cause pain, heaviness, swelling, itching, and cosmetic concerns. They happen when the valves inside veins become weak and blood flows backward, pooling in the legs. Over time, this can lead to skin changes, ulcers, and significant discomfort. EVLA offers a safe and effective solution for patients who want lasting relief with minimal downtime.
What is Endovenous Laser Ablation?
Endovenous Laser Ablation is a minimally invasive procedure that uses laser energy to treat varicose veins. The term endovenous means inside the vein. During the procedure, a thin laser fiber is inserted into the affected vein through a small puncture in the skin. Laser energy is then delivered to the vein wall, causing it to heat up, collapse, and seal shut.
Once the vein is closed, blood naturally reroutes through healthier veins in the leg. The treated vein is gradually absorbed by the body over time. This improves circulation, reduces symptoms, and improves the appearance of the legs.
EVLA is performed under local anesthesia, meaning the patient is awake but the area is numbed. It is usually done as a day care procedure, and most patients can go home the same day. The entire process typically takes about 30 to 60 minutes per leg, depending on the number and size of veins being treated.
How Does EVLA Work?
EVLA works by using controlled laser energy to damage the inner lining of the diseased vein. This causes the vein wall to shrink and close. The body then naturally absorbs the closed vein over weeks to months.
Key steps in how EVLA works
- A small puncture is made in the skin, usually near the knee or ankle.
- A thin catheter with a laser fiber is guided into the varicose vein using ultrasound.
- Local anesthesia is injected around the vein to numb the area and protect surrounding tissue.
- Laser energy is delivered as the catheter is slowly pulled back.
- The heat from the laser seals the vein shut.
- Blood flow is redirected to healthy veins.
- The treated vein gradually fades and is absorbed by the body.
Why laser energy is effective
Laser energy provides precise, controlled heat that targets only the diseased vein. It causes immediate closure of the vein and prevents blood from pooling. This reduces pressure in the leg veins and improves overall circulation. The surrounding healthy veins are not affected and continue to function normally.
Who is a Candidate for EVLA?
Not everyone with varicose veins needs EVLA, but many patients benefit from it. A vascular specialist will evaluate the veins using ultrasound to determine if EVLA is suitable.
Ideal candidates include:
- Patients with symptomatic varicose veins causing pain, heaviness, or swelling.
- People with visible bulging veins in the legs.
- Patients with skin changes or discoloration due to vein disease.
- Individuals who have tried conservative treatments without sufficient relief.
- People who want a minimally invasive option with quick recovery.
- Patients with ultrasound-confirmed vein reflux or valve dysfunction.
- Adults in good general health who can walk after the procedure.
Patients who may not be suitable
- Pregnant or breastfeeding women, as treatment is usually postponed.
- Patients with severe arterial disease or poor circulation.
- People with active infection or blood clotting disorders.
- Patients who cannot walk after the procedure.
- Individuals with very small or superficial veins that may need different treatment.

EVLA Procedure Steps
The procedure is performed in a specialized procedure room or operating theater with ultrasound guidance.
Step-by-step procedure
- The patient lies on the procedure table with the leg exposed.
- Ultrasound is used to mark the vein to be treated.
- The skin is cleaned and numbed with local anesthesia.
- A small puncture is made in the skin using a needle.
- A thin catheter with laser fiber is inserted into the vein.
- Ultrasound confirms correct placement of the catheter.
- Additional local anesthesia is injected around the vein for comfort and protection.
- Laser energy is activated as the catheter is slowly withdrawn.
- The vein seals shut as the laser moves along its length.
- The catheter is removed and a small bandage is applied.
- Compression stockings are placed on the leg.
- The patient is asked to walk for a few minutes to ensure good circulation.
Duration and anesthesia
- The procedure typically takes 30 to 60 minutes per leg.
- Local anesthesia is used, so the patient is awake but comfortable.
- Some patients may receive mild sedation if needed.
- No stitches are required in most cases.
Recovery After EVLA
