What is Endovenous Thermal Ablation?
Endovenous Thermal Ablation is a procedure that uses a laser or high-frequency radio waves to create just the right amount of heat to shrink the problematic veins in the legs. After the vein shrinks, the body automatically routes the blood through other, healthy veins. This procedure is generally performed on large varicose veins.
Endovenous Thermal Ablation Procedure
You will be offered a relaxing medication before the procedure. Your leg is sterilized and local anesthesia is applied to the treatment area. A catheter is inserted into the vein through a small incision generally below the knee. The ablation device is then inserted into the catheter. When the ablation device is turned on, the heat it generates closes the vein and the catheter is slowly pulled down the length of the vein, closing it permanently.
Endovenous thermal ablation is a minimally invasive, in-office procedure that lasts approximately one hour. After the procedure, prescription strength compression stockings must be worn for a short time. However, you’ll be able to resume most normal activities almost immediately. There is virtually no scarring from the procedure because the incision to insert the catheter is only a few millimeters in length.
