Endovenous Laser Ablation (EVLA) is a minimally invasive treatment that uses laser energy to close faulty varicose veins. It is a safe, effective alternative to surgery, with high success rates, minimal downtime, and long-lasting symptom relief.
What does Endovernous Laser Ablation mean?
- ‘Endovenous’ means ‘inside the vein’
- ‘Laser’ is heat energy transmitted by light
- ‘Ablation’ means to ‘destroy’
Therefore, Laser Ablation literally means to destroy veins from the inside with laser. It is an advanced technique that uses heat from a laser to seal off varicose veins and prevent the flow of blood.
Below are 10 key facts about Endovenous Laser Ablation (EVLA). This article explains why it is the treatment of choice for both physicians and patients.
10 Key Facts About Endovenous Laser Ablation (EVLA)
-
EVLA Treats the Varicose Veins
EVLA targets the faulty varicose vein. By sealing the diseased vein, blood is naturally redirected into healthy veins, improving circulation and reducing symptoms such as pain, swelling, and heaviness.
-
EVLA Is a Minimally Invasive Procedure
EVLA is performed through a small needle-sized entry point, not surgical incisions. This means:
- No stitches
- Minimal scarring
- Faster recovery compared to traditional vein surgery
-
The Procedure Is Performed Under Local or Regional Anaesthetic
EVLA does not require general anaesthetic. Local anaesthetic is used along the vein to keep patients comfortable throughout the procedure, making it suitable for most adults, including older patients. Some doctors will also use a regional anaesthetic for enhanced anaesthesia during the procedure.
-
EVLA Has a Very High Success Rate of 98%
Clinical studies show EVLA successfully closes the treated vein in about 92-98% of cases at 5 years. Most patients experience significant improvement in symptoms and appearance, with long-term results when combined with proper assessment and follow-up care.
-
EVLA Is Not the Same as Cosmetic Laser Treatments
EVLA treats veins from the inside, using laser energy delivered directly into the vein under ultrasound guidance. This is different from surface laser treatments, which are typically used for small spider veins on the skin which is sometimes known as “exo-laser”.
-
The Procedure Is Guided by Ultrasound
Ultrasound imaging is used throughout EVLA to:
- Identify the faulty vein
- Guide accurate laser placement
- Ensure the vein is fully sealed
This precision improves safety and long-term outcomes.
-
Recovery After EVLA Is Usually Quick
Most patients:
- Walk immediately after the procedure
- Return to normal daily activities within 24–48 hours
- Experience mild bruising or tenderness that settles within days
Compression stockings may be recommended for a short period after treatment.
-
EVLA Reduces Symptoms, Not Just Visible Veins
In addition to improving the appearance of varicose veins, EVLA commonly relieves:
- Aching or throbbing legs
- Heaviness or fatigue
- Swelling around the ankles
- Night cramps or itching
Symptom improvement is often noticed within hours of the treatment.
-
EVLA Is Safer and More Effective Than Traditional Surgery
Compared to vein stripping surgery, EVLA:
- Has fewer complications
- Involves less pain
- Requires shorter recovery time
- Has lower recurrence rates
For this reason, EVLA has largely replaced surgery for suitable patients.
-
EVLA Is Not Suitable for Every Vein Without Assessment
While EVLA is highly effective, not all veins are treated with the same method. A comprehensive vein assessment and duplex ultrasound are essential to determine:
- Whether EVLA is appropriate
- If additional treatments (e.g. sclerotherapy) are required
A personalised treatment plan delivers the best results.
Frequently Asked Questions
- Is EVLA painful?
Most patients experience minimal discomfort during EVLA due to local anaesthetic and even less with a regional anaesthetic. Mild tenderness or tightness afterward is common and temporary. - How long does EVLA last?
Once a vein is successfully closed, it does not reopen in most cases. EVLA provides long-term results, although new veins can develop over time due to underlying venous disease. - Is EVLA covered by Medicare or private health insurance?
In Australia, a portion of the treatment may be covered by Medicare and private health insurance when medically indicated. Eligibility depends on symptoms, ultrasound findings, and individual policy terms.
Bottom Line
EVLA is a safe, effective, and minimally invasive treatment for varicose veins that addresses the underlying cause rather than just surface appearance. With high success rates and rapid recovery, it is one of the most recommended treatments for venous reflux today.
