Success rate 99,5%
Endovenous laser ablation (EVLA) has an initial vein closure rate of 99.5%. This rate is significantly higher compared to traditional vein stripping surgery, which has a recurrence rate of nearly 50% after five years.
What is endovenous laser ablation (EVLA)? Endovenous laser ablation (EVLA)—also known as long-pulsed laser therapy—uses thermal energy to induce fibrosis within the vein, effectively sealing off the dilated vein. This method is highly recommended (Level I recommendation, Grade A evidence) by vascular societies worldwide for its safety and efficacy in treating bulging varicose veins from grade 2 and above. It offers excellent cosmetic outcomes and leaves no scars.
The procedure begins with the insertion of a sheath to guide the laser fiber to the targeted vein, under ultrasound guidance for precision. A cooling tumescent solution and local anesthesia are injected around the vein to protect surrounding tissues from thermal damage. The laser then delivers thermal energy to contract and seal the incompetent vein.
EVLA Laser – a method recommended by the International Union of Phlebology (UIP)
Endovenous laser ablation (EVLA), also known as long-pulsed laser therapy, is a technique in which a laser fiber is inserted into the vein and guided under ultrasound to the precise treatment site. Along the length of the vein, a tumescent solution is injected to provide local anesthesia and cooling, protecting surrounding tissues from thermal injury. The incompetent vein is thermally ablated, causing it to collapse and seal from within. The treated vein will be naturally absorbed by the body within a few months. This is a minimally invasive procedure that allows for quick recovery.
According to Dr. Le Kim Cao: “For patients with bulging varicose veins (grade 2), endovenous long-pulsed laser (EVLA) is strongly recommended at the highest level by the International Union of Phlebology (UIP), with Level I recommendation and Grade A evidence according to evidence-based medicine.”
Steps of EVLA Treatment
- A sheath is inserted to guide the laser fiber into the vein. The surgeon monitors the position in real time using ultrasound imaging.
- A tumescent solution is then injected to cool and anesthetize the area around the vein. This solution helps protect surrounding tissues from heat.
- Thermal energy is activated to ablate the incompetent vein.
- The heat from the laser causes the vein to collapse and seal shut. The vein is then gradually absorbed by the body, eliminating the need for surgical removal.
Advantages of EVLA Laser in the Treatment of Venous Insufficiency
With a first-time treatment success rate of over 99% and a sustained success rate of over 95% after five years, EVLA is one of the most highly recommended methods worldwide for treating venous insufficiency, especially for hidden varicose veins.
This is a minimally invasive procedure. The vein is not surgically removed from the body, so no scarring is left, and recovery time is fast. Bruising and discomfort are minimal after the procedure.
The treatment is performed quickly, typically within one hour, without the need for hospitalization or general anesthesia.
Return to daily activities within 24 hours
EVLA is a minimally invasive procedure. You can return to work and normal activities the day after treatment.
Immediate improvement
This method is highly recommended for its safety and definitive treatment results. Many patients report noticeable symptom relief immediately after the procedure.
Safe and effective
Minimally invasive approach reduces patient discomfort, enables faster recovery, and is suitable for multiple stages of venous insufficiency.
Post-EVLA Care Instructions
After EVLA treatment, patients will be instructed to wear compression stockings or follow a prescribed compression regimen. Two weeks after the procedure, patients will return for an ultrasound check to monitor the healing process. It is important to strictly follow the physician’s instructions to ensure optimal and timely recovery.
Standardized Medical Protocol
Direct consultation with a vascular surgeon
Accurate, in-depth assessment following a medically standardized protocol
Exclusion-based diagnosis
Used to rule out comorbid conditions that present with similar symptoms to varicose veins, such as herniated disc or spinal degeneration related to musculoskeletal disorders.
Doppler ultrasound
Advanced vascular ultrasound performed in both standing and supine positions to assess venous reflux and evaluate lower limb venous hemodynamics, aiming to detect pathological reflux flow (reflux sign).
Determine the severity
Accurately determining the severity of venous insufficiency is essential, especially in cases involving hidden varicose veins or associated complications.
Formulate a treatment strategy
Consultation with a vascular specialist is essential to accurately assess the condition of venous insufficiency and develop an appropriate treatment plan.
Scheduled Follow-Up
The patient will continue to be monitored and scheduled for regular follow-up appointments as advised by the specialist.
