What Is EVLA? A Patient's Guide to Endovenous Laser Ablation
If you have varicose veins or another condition involving venous reflux, you may have come across the term EVLA, or endovenous laser ablation. EVLA is a minimally invasive procedure used to treat certain veins when their valves are not functioning effectively and blood is flowing backward or pooling within the vein.
Understanding what EVLA is, how the procedure generally works, and what patients may expect can make conversations about potential vein treatment easier. EVLA is not appropriate for every patient with visible veins, and whether it is recommended depends on an individualized vascular assessment.
At Atrium Vascular, we provide specialized vascular services for referred patients from Richmond Hill, Markham, Vaughan, Aurora, Scarborough, North York, and communities throughout the Greater Toronto Area (GTA).
What Does EVLA Mean?
EVLA stands for endovenous laser ablation. It may also be referred to as endovenous laser treatment or EVLT.
“Endovenous” means that the treatment takes place from inside the vein. During EVLA, a thin laser fibre is introduced into the affected vein. Laser energy is then used to heat the vein wall, causing the treated vein to close.
Once the vein has been closed, blood is naturally redirected through other functioning veins. Over time, the treated vein is gradually broken down and absorbed by the body.
Why Is Endovenous Laser Ablation Performed?
EVLA can be used to treat certain superficial veins affected by venous reflux.
Healthy leg veins contain one-way valves that help blood travel toward the heart. When these valves become ineffective, blood can flow backward and increase pressure within the venous system. This may contribute to varicose veins and symptoms such as aching, heaviness, swelling, throbbing, or other changes involving the lower legs.
The goal of EVLA is to close an appropriately selected refluxing vein so blood can be redirected through healthier veins.
Not everyone with varicose veins requires EVLA. The appropriate treatment depends on which veins are affected, the patient’s symptoms, vascular testing, medical history, and other individual factors.
What Happens During an EVLA Procedure?
The exact process can vary depending on the patient and treatment plan. In general, ultrasound imaging is used to identify and guide treatment of the affected vein.
A small access point is made so that a thin catheter or laser fibre can be positioned within the vein. Local anaesthetic is commonly used around the treatment area. Once the fibre is appropriately positioned, controlled laser energy is delivered as it is withdrawn through the vein.
The heat causes the targeted vein to close.
Because EVLA is performed through a small access point rather than a large surgical incision, it is considered a minimally invasive vein treatment.
Your vascular specialist can explain the specific technique, anaesthesia, expected duration, and other details relevant to your procedure.
What Is Recovery Like After EVLA?
Recovery varies between patients, so post-procedure instructions should come from the healthcare team responsible for your treatment. Many patients are encouraged to walk following endovenous procedures, but recommendations regarding activity, work, exercise, bathing, and other aspects of recovery can vary.
Some people may experience temporary bruising, tenderness, tightness, or discomfort around the treated area. Your healthcare provider should explain which symptoms may be expected and which should prompt medical attention.
Compression stockings may also be recommended following certain vein procedures. If compression is included in your care plan, follow the specific instructions provided regarding the garment, fit, pressure, and duration of use.
Does EVLA Permanently Cure Varicose Veins?
EVLA is intended to close the vein being treated, but it should not be described as a guaranteed permanent cure for all varicose veins or venous disease.
Other veins can become problematic over time, and some patients may require additional monitoring or treatment depending on their vascular health.
A physical examination may help identify changes involving your legs, skin, veins, or circulation. Depending on your symptoms and clinical findings, additional vascular testing may be recommended to better understand blood flow.
Your vascular specialist can discuss expected outcomes, possible recurrence, alternative treatments, potential risks, and whether EVLA is appropriate based on your individual assessment.
Are There Risks With Endovenous Laser Ablation?
Like any medical procedure, EVLA has potential risks and complications.
These vary depending on the patient and procedure and should be reviewed with the treating vascular specialist as part of informed consent. Potential complications can include pain or bruising, skin or nerve-related symptoms, inflammation, infection, and blood-clot-related complications, among others.
The presence of potential risks does not mean they will occur. Your healthcare provider can explain the expected benefits and risks based on your individual circumstances.
