Endovenous thermal ablation is a minimally invasive treatment used to close damaged veins and reduce the symptoms associated with varicose veins. By improving circulation and addressing visible vein concerns, this approach supports both comfort and long-term vein health.
Treatment at Hawaii Vein Institute is guided by Dr. W. Y. Chung, MD, RPh, DABVLM, who brings decades of experience in venous and laser-based procedures. His background in both emergency medicine and venous care allows for a thorough, detail-oriented approach to diagnosis and treatment. Endovenous thermal ablation offers an effective option for patients seeking reliable results without the need for traditional surgery.

What is Endovenous Thermal Ablation (ETA)?
Endovenous thermal ablation is a minimally invasive treatment for varicose veins that closes them from the inside. Heat from either radiofrequency or laser energy is applied to the vein, causing it to seal and stop functioning.
Ultrasound guidance is used throughout the procedure to ensure precise placement of a thin fiber within the vein. Once the vein is closed, your body naturally redirects blood flow to healthier veins, helping improve circulation.
Over time, the treated vein is absorbed by your body. This not only helps relieve symptoms like discomfort or heaviness but also improves the overall appearance of your legs.
The Benefits of Endovenous Thermal Ablation (ETA)
Endovenous thermal ablation is designed to give you effective relief from varicose veins without the need for traditional surgery. It allows you to address both discomfort and visible vein concerns while quickly getting back to your normal routine.
Benefits of this treatment include:
- Minimally invasive treatment that avoids large incisions
- A quick procedure, often completed in under an hour
- Fast recovery with little interruption to your daily activities
- A high success rate with a low risk of complications
- Noticeable improvement in both how your legs feel and look
The Procedure
Endovenous thermal ablation is performed as an outpatient procedure and is designed to be both comfortable and efficient. Each step is focused on treating the affected veins while helping you feel at ease throughout the process.
- Consultation: Your veins are evaluated using ultrasound imaging to identify the source of the problem and determine if this treatment is right for you
- Preparation: The treatment area is cleaned, and local anesthesia is used to keep you comfortable during the procedure
- Treatment: A thin fiber is inserted into the affected vein through a small entry point. As it is slowly withdrawn, controlled heat is applied to seal the vein
- Recovery: You will be encouraged to walk right after the procedure to support circulation. Compression stockings may be recommended, and most patients return to normal activities within a short time
Post-Treatment Care
Post-ETA care is straightforward. Patients are encouraged to walk immediately after the procedure and can typically return to everyday activities the same day. Some bruising or swelling may occur, but usually subsides within a few weeks. Follow-up appointments are essential to monitor the healing process and to ensure the vein has closed effectively.
