What is EVLT Vein Treatment?

Endovenous Laser Treatment, commonly referred to as EVLT, is a widely used procedure for treating varicose veins. It is a minimally invasive technique that uses targeted laser heat to close a faulty vein from the inside. Once the vein is sealed, blood flow is naturally redirected to nearby healthy veins, improving circulation.

Over recent years, EVLT has become a preferred option within vascular care in the UK. It yields effective results with a shorter recovery period than traditional surgical approaches. For many patients, it provides relief from both the visible appearance of varicose veins and the symptoms that often accompany them.

Varicose Veins

Varicose veins develop when the valves inside the veins no longer function properly. These valves are responsible for keeping blood moving in the correct direction, back towards the heart. When they weaken or fail, blood can collect within the vein, increasing pressure and causing it to enlarge.

This process leads to veins that appear swollen, twisted, and raised beneath the skin. They are most commonly found in the legs due to gravity and the pressure of standing and walking.

Symptoms can vary from mild to more persistent discomfort. Patients often report aching, heaviness, swelling around the ankles, and irritation of the surrounding skin. In some cases, untreated venous disease may progress and affect skin quality over time.

Suitability For EVLT

EVLT is not necessary for every visible vein. It is typically recommended when there is clear evidence of venous reflux, which means blood is flowing in the wrong direction within the vein.

A full clinical assessment is required before treatment is considered. This usually includes a detailed medical history and a duplex ultrasound scan. The scan allows the clinician to map the veins, assess valve function, and identify the source of the problem.

Patients with straightforward superficial venous reflux are often suitable for EVLT. In cases where the vein issue is linked to prior surgery, deep vein conditions, or other underlying causes, alternative treatments, such as foam sclerotherapy, may be more appropriate.

Clinical Guidance

Guidance from the National Institute for Health and Care Excellence supports the use of endovenous treatments such as EVLT as a first-line option for suitable patients with varicose veins. The NICE CG168 recommends endothermal ablation as the initial treatment approach where venous reflux is confirmed.

If EVLT is not suitable, ultrasound-guided foam sclerotherapy may be considered. Traditional surgery is generally reserved for cases where less invasive options are not appropriate. These recommendations are based on clinical evidence showing strong outcomes and a favourable recovery profile.

Treatment Process

EVLT is performed as an outpatient procedure under local anaesthesia. It is designed to be efficient and well-tolerated, with most treatments completed within an hour.

The process begins with ultrasound mapping of the affected vein. The skin is then numbed along the course of the vein using a local anaesthetic. A fine needle is used to access the vein, and a thin catheter is inserted. Through this catheter, a laser fibre is carefully guided to the top of the vein.

Once in position, the laser is activated. As the fibre is slowly withdrawn, controlled heat is delivered to the vein wall. This causes the vein to collapse and seal. Over time, the body absorbs the treated vein.

A dressing is applied after the procedure, and compression stockings are fitted to support healing. Patients are encouraged to walk soon after treatment to support healthy circulation.

Preparation Before Treatment

Preparation for EVLT is straightforward but important for ensuring safe and effective care. During consultation, your clinician will review your overall health and discuss any factors that may influence treatment.

You will be asked about current medications, lifestyle habits such as smoking and alcohol intake, and any medical conditions, including diabetes or kidney disease. It is also important to mention pregnancy or breastfeeding.

Clear guidance will be provided before your appointment, including advice on clothing, activity, and any medication adjustments if required.

Recovery and Aftercare

Recovery following EVLT is usually quick, with many patients returning to normal activities within a short period. Walking is encouraged on the same day to support circulation and reduce the risk of complications.

Compression stockings are worn for a period recommended by your clinician. These help reduce swelling, support the treated vein, and improve overall comfort.

It is advisable to avoid heavy lifting, prolonged standing, and high-impact exercise for a couple of weeks. Hot baths and saunas are also avoided during early recovery, as heat can affect the healing process.

Mild discomfort, tightness, or bruising along the treated vein is common and typically settles without intervention.

Additional Treatment Options

EVLT addresses the underlying cause of varicose veins, but it may not remove all visible veins. For this reason, additional varicose vein treatments are sometimes recommended to achieve a more complete result.

Foam sclerotherapy is commonly used to treat residual veins after EVLT. A specially prepared solution is injected into the vein, causing it to close and gradually fade.

Microphlebectomy may also be considered for larger surface veins. This involves removing sections of vein through very small incisions under local anaesthetic. Scarring is minimal, and the procedure can often be performed alongside or after EVLT.

Risks and Safety Considerations

EVLT is considered a safe procedure when carried out by an experienced vascular specialist. As with any medical treatment, there are some risks to be aware of, although these are uncommon.

Possible side effects include temporary bruising, inflammation of the treated vein, and mild discomfort. In rare cases, complications such as infection, nerve irritation, or deep vein thrombosis may occur.

Patients are provided with clear aftercare instructions and follow-up appointments to monitor progress and address any concerns.

Benefits Of EVLT

EVLT offers several advantages that make it a suitable option for many patients. The procedure is performed under local anaesthetic and does not require a hospital stay. Treatment times are short, and recovery is generally rapid.

Patients can return to normal routines quickly, often on the same day. There is minimal scarring, and the procedure is associated with high rates of vein closure.

In addition to improving the appearance of the legs, EVLT often relieves symptoms such as aching, heaviness, and swelling.

Effectiveness and Success Rates

Clinical evidence in the UK supports the use of EVLT as an effective treatment for varicose veins. Vein closure rates are typically reported above 90 per cent.

Success depends on several factors, including the size and position of the vein and adherence to aftercare advice. While the treated vein does not reopen, new veins may develop over time if there is an underlying tendency.

Regular follow-up and early assessment of new symptoms can help maintain results over the long term.

Results and Outlook

Changes are often noticeable within the first few weeks after treatment. The treated vein gradually fades as the body breaks it down. Full results may take a few months to become apparent.

Patients usually experience both cosmetic and physical improvement. The legs may feel lighter, and visible bulging is reduced.

Maintaining a healthy weight, staying active, and wearing compression when advised can support vein health.
