Endovenous Laser Ablation Therapy (EVLT)

Endovenous laser ablation is a minimally invasive treatment option for varicose veins that uses laser energy to seal off the affected veins. This procedure offers an alternative to traditional surgery, with the goal of providing relief from symptoms such as pain, swelling and leg heaviness. The Vascular Institute of San Antonio, part of the Baptist Medical Network, offers EVLT along with a range of services for various vascular conditions. With a team of qualified professionals, an array of accepted insurance plans and a commitment to patient care, the Vascular Institute of San Antonio aims to help individuals address their vein health concerns.

What Is Endovenous Laser Ablation? 

Endovenous laser ablation (EVA or EVLT) is a treatment for varicose veins, a condition that affects up to 40% of adults. Varicose veins, the enlarged, twisted veins typically seen in the legs, arise from venous valves' malfunction and decreased vein wall elasticity, leading to blood pooling. EVA addresses this issue directly by using laser energy to heat the inside of the vein, causing it to collapse and seal shut. This procedure is performed under local anesthesia in an outpatient setting, making it minimally invasive compared to traditional surgical methods like vein stripping.

EVA has several advantages over traditional treatments. It is less invasive, requires no general anesthesia and typically allows patients to return to their daily activities much sooner, often within a day. Studies have shown a high success rate, with 96.7% of treated veins remaining closed after three to five years. However, like any medical procedure, EVA carries risks of complications such as thrombosis, skin burns, nerve damage and the possibility of varicose vein recurrence. Despite these risks, EVA is an effective treatment for varicose veins, offering significant relief from symptoms and improving patients' quality of life.

How Does Endovenous Laser Ablation Work? 

The procedure begins with a thorough evaluation of the patient's venous system using duplex ultrasound, which helps map the veins and identify areas of reflux. Once the target vein is identified, a thin fiber-optic laser is inserted into it. When activated, the laser delivers precise energy to the vein's walls, heating them and causing the vein to collapse and eventually be absorbed by the body. Tumescent anesthesia is applied around the vein to provide local pain relief and protect the surrounding tissues from heat damage.

What To Expect After Vein Ablation? 

After undergoing vein ablation, patients can expect a series of outcomes and post-procedure experiences. This minimally invasive procedure may offer a quicker recovery compared to traditional surgery, with many individuals returning to their daily activities almost immediately. However, it's crucial to understand what follows the treatment to ensure a smooth recovery and optimal results. After EVLT, you may expect:

• Immediate Post-Procedure: Most patients are encouraged to walk shortly after the procedure to promote blood flow. Mild soreness or bruising around the treated area is common.
• Recovery Period: Recovery is typically fast, with many individuals resuming work and normal activities within a day. However, strenuous activities should be avoided for a short period, as advised by your healthcare provider.
• Compression Garments: Wearing compression stockings is often recommended for a certain period after the procedure to support vein healing and reduce swelling.
• Follow-Up Care: Follow-up visits are crucial to monitor the success of the ablation and to check for any complications. Duplex ultrasound may be used during these visits to ensure the treated vein remains closed.
• Symptom Improvement: Patients may notice an improvement in symptoms related to varicose veins, such as pain, swelling and leg heaviness, within weeks of the procedure.
• Long-Term Results: The success rate of vein ablation is high, with many studies reporting over 90% efficacy. However, lifestyle adjustments may be recommended to prevent new varicose veins from developing.

It's important to discuss with your healthcare provider about any specific post-procedure instructions to follow, including pain management and signs of potential complications, such as deep vein thrombosis. While vein ablation offers a safe and effective treatment for varicose veins, understanding and adhering to post-treatment guidelines are key to achieving the best outcomes and maintaining vein health.
