Minimally Invasive Treatment for Varicose Veins
Varicose veins can cause more than visible changes in the legs when weakened vein valves interfere with normal blood circulation. Aching, heaviness, swelling and tiredness may develop when blood begins to move backwards through an affected vessel. Endovenous Laser Ablation (EVLA) Pickering is a minimally invasive treatment that may be considered for appropriately selected patients with symptomatic varicose veins associated with venous reflux. At Atrium Vascular Associates, Dr. Sydney Wong, M.D., FRCSC, evaluates each patient’s vascular condition before determining whether laser treatment is an appropriate option.
When Varicose Veins Need More Than Cosmetic Treatment
Visible veins are not necessarily a medical problem, but persistent symptoms can indicate an underlying issue with venous circulation. When the valves inside a vein become ineffective, blood may flow in the wrong direction and increase pressure within the vessel.
Symptoms may include:
- Aching or throbbing sensations in the legs
- Heavy or fatigued legs
- Swelling around the ankles
- Discomfort following prolonged standing
- Enlarged or twisted surface veins
- Symptoms that become more noticeable later in the day
- Certain skin changes associated with chronic venous disease
When these concerns are connected to venous reflux, Endovenous Laser Ablation (EVLA) Pickering may be discussed as part of an individualized treatment plan.
Understanding Venous Reflux
Vein valves normally help maintain one-way blood flow towards the heart. If these valves become weakened or damaged, they may allow blood to travel backwards and accumulate in the affected vessel.
This condition is known as venous reflux. The increased pressure can contribute to enlarged veins and symptoms that develop or worsen over time.
When required, specialized vascular ultrasound, Ankle-Brachial Index (ABI) testing, and CTA imaging can be arranged through appropriate diagnostic facilities to assess blood flow and identify the underlying cause of symptoms.
These findings can help determine whether Endovenous Laser Ablation (EVLA) Pickering is suitable for the vein responsible for abnormal blood flow.
How EVLA Fits Into Modern Vein Care
Endovenous Laser Ablation (EVLA) Pickering uses controlled laser energy to close a problematic vein from within. Instead of removing the vessel through traditional surgery, the treatment targets the affected vein internally.
Ultrasound guidance is used to position a small catheter inside the selected vein. A fine laser fibre is then introduced through the catheter, allowing controlled thermal energy to be applied along the treatment area.
The heat causes the vein to close, after which blood can be redirected through healthier veins. This minimally invasive approach allows treatment of venous reflux without conventional surgical removal of the affected vessel.
Could EVLA Be Suitable for Your Veins?
Laser ablation is not appropriate for every patient with varicose veins. The suitability of Endovenous Laser Ablation (EVLA) Pickering depends on the patient’s symptoms, the anatomy of the affected vein, the presence of reflux and overall vascular health.
EVLA may be considered when:
- A particular vein has been identified as contributing to reflux.
- Varicose veins are associated with ongoing symptoms.
- The affected vessel is suitable for endovenous treatment.
- Conservative measures have not adequately addressed the symptoms.
- Clinical assessment supports closing the problematic vein.
A vascular specialist can review these factors and recommend an approach suited to the individual patient.
Before Treatment
Before Endovenous Laser Ablation (EVLA) Pickering, your symptoms, medical history and relevant vascular findings are reviewed. You may discuss when your symptoms started, whether swelling occurs and whether standing, walking or other activities affect your legs.
The location and characteristics of the affected veins are also considered during treatment planning. This helps ensure that management is focused on the underlying venous problem rather than simply treating the appearance of visible veins.
During Treatment
During Endovenous Laser Ablation (EVLA) Pickering, ultrasound imaging is used to guide the physician and accurately identify the vein being treated.
Local anaesthetic is generally applied around the treatment area. A small access point allows a catheter to be inserted into the affected vessel. A narrow laser fibre is then positioned through the catheter.
Controlled thermal energy is delivered along the targeted portion of the vein. The resulting heat causes the vessel to close, allowing blood to travel through healthier veins elsewhere in the leg.
The exact treatment approach can vary depending on the patient’s vein anatomy and the characteristics of the affected vessel.
After Treatment
Recovery following Endovenous Laser Ablation (EVLA) Pickering is generally intended to be less disruptive than recovery from traditional vein surgery. Many patients can walk following the procedure and return to light activities relatively soon, although recovery varies between individuals.
Aftercare may include:
- Walking according to your physician’s instructions
- Wearing compression stockings if recommended
- Temporarily avoiding strenuous exercise
- Monitoring the treated area
- Following recommended follow-up care
Your physician will advise you when it is appropriate to resume exercise, physically demanding work and other activities.
What Happens to the Treated Vein?
After Endovenous Laser Ablation (EVLA) Pickering, the targeted vein remains closed rather than being surgically removed.
Blood can be redirected through healthier functioning veins, while the body gradually processes the closed vessel. The purpose of treatment is to reduce abnormal flow through the affected vein while preserving circulation through the rest of the venous system.
Since venous disease can affect multiple vessels, treating one refluxing vein does not necessarily prevent other varicose veins from developing in the future.
EVLA Compared With Other Vein Treatments
Several approaches may be used to manage varicose veins and venous reflux. The appropriate option depends on the patient’s vascular findings, symptoms and vein anatomy.
Compression Therapy
Compression stockings provide support to the legs and may help manage swelling and other venous symptoms. They can be part of conservative care but do not directly close a vein affected by reflux.
Sclerotherapy
Sclerotherapy involves injecting a solution into selected veins to encourage them to close. It may be appropriate for certain smaller veins or particular patterns of venous disease.
Surgical Treatment
Traditional vein surgery can involve removing or tying off problematic vessels. For appropriately selected patients, Endovenous Laser Ablation (EVLA) Pickering provides a minimally invasive method of closing a refluxing vein without conventional surgical removal.
A vascular specialist can compare these options based on the patient’s individual circumstances.

Frequently Asked Questions (FAQs)
Is EVLA painful?
Local anaesthetic is generally used during Endovenous Laser Ablation (EVLA) Pickering to help maintain comfort during treatment. Some patients may experience pressure, warmth or other sensations during the procedure.
Can I walk after EVLA?
Walking is commonly encouraged following treatment when medically appropriate. Your physician will provide specific instructions regarding movement and activity after the procedure.
How quickly can I return to normal activities?
Many patients can resume light daily activities relatively soon after treatment. The appropriate timing for returning to strenuous exercise or physically demanding work varies according to individual recovery.
Will I need compression stockings?
Compression stockings may be recommended after Endovenous Laser Ablation (EVLA) Pickering. Your physician will determine whether they are appropriate and provide instructions for their use.
Is EVLA a permanent treatment?
The treated vein is closed, but venous disease can affect other vessels. New reflux or varicose veins may develop over time, so treating one vein does not guarantee that future vein problems will not occur.
Is laser ablation suitable for everyone?
No. Endovenous Laser Ablation (EVLA) Pickering is intended for appropriately selected patients. The affected vein’s anatomy, vascular findings, symptoms and overall health should be evaluated before treatment is recommended.
Take the Next Step Towards Better Vein Health
Persistent leg aching, heaviness, swelling or prominent varicose veins can sometimes be associated with an underlying venous circulation problem. Identifying the cause of these symptoms can help you understand which treatment options may be suitable.
