Endovenous Laser Treatment (EVLT)

Endovenous Laser Treatment, or EVLT, is used to close a refluxing vein from the inside. It is commonly recommended when ultrasound shows that a saphenous vein or related superficial vein is allowing blood to flow backward and contribute to varicose veins or symptoms.

EVLT does not remove the vein. Instead, laser energy seals the vein closed. Blood naturally redirects through healthier veins, and the treated vein gradually shrinks over time.

• Venous reflux disease
• Saphenous vein insufficiency
• Varicose veins caused by reflux
• Bulging veins fed by a refluxing source vein
• Aching, heaviness, fatigue, swelling, or throbbing related to reflux
• Selected skin changes caused by chronic venous hypertension

Using ultrasound guidance, the physician places a thin laser fiber inside the target vein through a small access point. Local anesthesia is used around the vein. Laser energy heats the inside of the vein, causing it to close.

EVLT is performed in the office. Most patients walk shortly after the procedure. Compression stockings, walking, and a follow-up ultrasound may be part of the aftercare plan.

Mild tightness, soreness, bruising, or tenderness along the treated vein can occur. Patients are usually encouraged to walk and avoid prolonged inactivity. Specific activity instructions vary by patient.

EVLT is often covered when there are documented symptoms, ultrasound-confirmed reflux, and insurance criteria are met. Many plans require a period of conservative care before authorization.
