What is Endovenous Thermal Ablation (EVTA)?

Endovenous thermal ablation (EVTA) is a minimally invasive, image-guided therapy used to treat varicose veins, which can cause leg pain, swelling, skin irritation and vein inflammation. During EVTA, heat energy damages the vein walls, shrinking them and closing the faulty vein so the blood cannot flow through it. This eliminates vein bulging at its source. After treatment, the blood in the faulty veins will be diverted to the many normal veins in the leg.

EVTA typically takes less than one hour.

How to Prepare for EVTA

  • Pre-Admission Testing - We will schedule an appointment for you. We may also draw blood to check various readings.
  • When to Arrive - Arrival time varies according to procedure. We will tell you what time to arrive when you make your appointment.
  • Clothing - We recommend wearing comfortable, loose-fitting clothing for EVTA. We may ask you to change into a hospital gown during the procedure.
  • Eating and Drinking - You may continue to eat and drink normally before your EVTA appointment.
  • Medications - It is important to tell us the names of any medications you are taking before your procedure. You may need to stop taking certain medications. In addition, you may be prescribed medication for you to take a few days before the procedure.

 What Happens After EVTA?

We encourage you to walk immediately after the procedure. You can immediately resume your normal daily activities but we recommend avoiding rigorous activities, such as gym workouts. You may experience minor soreness and bruising. You can treat any discomfort with over-the-counter, non-aspirin pain relievers as needed.
