What is endovenous thermal ablation?
Endovenous thermal ablation is a minimally invasive procedure to treat varicose veins. ClosureFast uses radiofrequency energy to safely and permanently eliminate your unsightly veins and restore healthy venous circulation.
What causes varicose veins?
Varicose veins develop when blood builds-up in a segment of the vein. The problem occurs when valves inside the vein fail. These valves normally keep blood flowing up your legs, working against gravity to return deoxygenated blood to your heart.
If a valve weakens, some of the blood refluxes or flows back down the leg and accumulates in the veins. This condition, called venous insufficiency, leads to enlarged, twisted, varicose veins.
What symptoms develop if I have varicose veins?
Some people never experience symptoms other than the unsightly appearance of varicose veins. Most people, however, have leg symptoms such as:
- Restless legs
- Swollen legs
- Skin discoloration
Venous insufficiency leads to complications in your lower leg. For example, you may develop venous stasis dermatitis, which is an eczema-like skin condition, or venous ulcers. Without medical care, these leg ulcers enlarge and lead to skin and bone infections.
What happens when I get endovenous thermal ablation?
This is how your varicose vein treatment unfolds at Advanced Heart & Vascular Associates:
Endovenous treatments are done inside the vein with a narrow catheter. With this approach, you only need local anesthetics, and your treatment is done in the office.
Dr. Chadda applies a topical anesthetic before making a tiny incision above the vein. The cut is just large enough to insert the catheter, and it barely leaves a scar.
Using ultrasound imaging to guide the procedure, Dr. Chadda threads the catheter through the vein to the end of the varicosity. Then he injects the vein with a local anesthetic before he activates the radiofrequency tip in the catheter.
Controlled thermal ablation
ClosureFast uses radiofrequency energy to produce controlled heat. The heat then ablates the inside of the vein, damaging the inner tissues to make the vein collapse.
After the vein closes, it turns into scar tissue that your body reabsorbs, making the treated veins disappear. Your body also restores healthy circulation by rerouting blood flow through healthy veins.
The ClosureFast system causes less pain and bruising compared to endovenous laser ablation. And the device is backed by studies showing that it’s safe and effective.
