Intravenous radiofrequency application (Endovenous radiofrequency ablation) was first used in 2007 as an alternative to the traditional surgical treatment used in the treatment of varicose veins. The procedure is based on the principle of penetrating the varicose vein with the help of doppler ultrasound and closing the vein completely with the heat energy generated by the radio waves. After the examination, your doctor will request a Doppler ultrasound test and will decide on the procedure according to the result. If there is an increase in diameter and advanced leakage in addition to your complaints in your leg vein in Doppler ultrasound, the procedure can be applied.
HOW IS IT APPLIED?
The procedure is performed in a sterile environment. It can be performed under general anesthesia or completely local anesthesia. However, if there is no special situation, the procedure is performed with local anesthesia and sedation. Local anesthesia and sedatives are used to avoid tension. With the help of a small needle, the vein is entered into the vein with the help of ultrasound from the area that was previously anesthetized with local anesthetic. With the help of a thin guide wire sent through the needle hole, the radiofrequency catheter is guided to the leaking area under Doppler ultrasound guidance. Then, a previously prepared solution is given around the vessel, known as “tumescent anesthesia”. The purpose of this is to protect the tissues against the heat energy released and to prevent nerve damage. After the catheter is seen to be in the safe area again by ultrasonography, a maximum of 120 degrees heat is transmitted to the vein wall for a period of 15 seconds with the help of the generator. After each 15-second application, the catheter is withdrawn to the next segment marked on it. Thus, continuous ablation treatment is applied throughout the varicose vein.
HOW IS THE PROCESS AFTER THE PROCEDURE?
Compression stockings (varicose stockings) or elastic bandage are applied immediately after the procedure. Regular walks are strongly recommended in the early period, starting immediately after the procedure. Daily activities can be continued easily. Heavy exercise and lifting weights are not recommended for at least 3 months.
WHAT ARE THE COMPLICATIONS?
Complications due to radiofrequency procedure The rate of licensing is quite low. The most common situations; bruising at the application site, loss of sensitivity or sensation, heat-induced skin burn, superficial thrombophlebitis. The worst complication, deep venous occlusion (DVT) and/or embolism to the pulmonary artery (Pulmonary Embolism), development rates are quite low.
