Endovenous Thermal Ablation

What is Endovenous Thermal Energy Treatment?

Endovenous Thermal Treatment is a minimally invasive ultrasound-guided method for treating varicose veins using energy, either laser of radio frequency. The energy is delivered through a fine optical fiber that is inserted into the underlying abnormal vein. This in-office treatment is performed with only local anesthesia and can bring rapid improvement of any symptoms associated with varicose veins or venous insufficiency. The goal of thermal is to treat the underlying abnormal vein(s) with the broken valves. The energy heats the vein at the tip of the optical fiber, causing the abnormal vein to close. Blood is routed to the normal functioning veins. With time the abnormal vein, treated by thermal energy, is broken down and resorbed by the body. The procedure takes less than one hour and you are able to walk out and resume most of your normal daily activities.

What are the Advantages of Thermal Energy Treatment?

No vein stripping – No surgery!
It is an in-office procedure – No hospitalization!
Walk in and walk out in about an hour!
A nearly pain-free procedure
Only requires local anesthesia
No scalpels, no incisions, and no unsightly scars
Immediate return to most normal activities
Thermal energy has a 98% success rate
Rapid recovery with minimal post-procedure pain
The procedure is covered by most medical insurance

What Should I Expect with Thermal Energy Treatment?

The first step in the evaluation of varicose veins or symptoms suggestive of venous insufficiency is to schedule a medical consultation with Tennessee Vein Center. As part of the consultation, we will determine if full evaluation with duplex venous ultrasound and venous mapping is appropriate and if you are a candidate for treatment. Most insurers require a documented trial of conservative treatment prior to approving the procedure. As part of the evaluation, you will be measured for or prescribed medical-grade compression hose.

On the day of the procedure, you should:

Avoid the use of lotion on the legs
Wear or bring a pair of loose-fitting shorts (We can provide disposable shorts if needed)
Bring your compression hose
Drink plenty of water on the day of treatment
Remember it is fine to eat on the day of the procedure, but you may want to avoid eating a heavy meal just prior to treatment and you may want to consider a light snack if it has been several hours since you last ate.

What Should I Expect After Thermal Energy Treatment?

Immediately after the procedure, you will be asked to put on your compression hose and walk or cycle for 10 minutes.
It is important for you to wear your medical-grade compression hose for 7-10 days after the procedure. Compression hose help your circulation and serve to reduce swelling, reduce inflammation, reduce complications, and speed healing.
During this healing process walking and normal daily activities are strongly encouraged.
Complications from the treatment are extremely rare.
Bruising, minor soreness, and a feeling of tightness are normal and will pass.
If needed, the mild discomfort can be relieved by an over the counter pain reliever.
A follow-up ultrasound will be scheduled.
Extremely strenuous activities should be avoided for a few days after the procedure.

Thermal energy treats the source of varicose veins and takes the pressure off of the visible varicose veins, allowing sclerotherapy treatment to be much more effective. Most patients will require sclerotherapy treatments to comprehensively address the entire problem.
