Radiofrequency ablation

Radiofrequency ablation is a minimally invasive x-ray surgical procedure. It is used in the treatment of arrhythmias, tachycardias, varicosities. Radiofrequency ablation is performed using an endovascular catheter that conducts high-frequency currents.

The mechanism of this method consists in the point electrode action on the areas with impaired conductivity, restoration of sinus rhythm and prevention of pathological impulse.

Radiofrequency ablation is prescribed for flutter and atrial fibrillation, tachycardia (AV node, atrial and ventricular). With the help of EFI, the problem area of the conducting system is determined, the electrode is applied to it and the effect is performed.

It should be noted that radiofrequency ablation of veins is one of the safest and least traumatic ways of treating varicose veins.

The treatment method is based on the use of microwave exposure. Thus, the thermal influence on the vein wall is produced, which, in turn, provokes vascular obliteration.

Radiofrequency ablation in phlebology has been applied relatively recently. This method came from cardiac surgery, where it was widely used in restoring the normal rhythm of the heart.

Radiofrequency obliteration can be used both as a single and independent method of exposure, and be included in a set of therapeutic measures to improve the effectiveness of treatment.

Before the procedure, the patient must necessarily undergo ultrasound scanning of all vessels in the lower limbs.

Based on the results of the study, the phlebologist specialist decides on the feasibility and feasibility of radiofrequency obliteration of the veins. Despite the fact that this technique makes it possible to level large enough vessels of the main network that have varicose veins, it is not acceptable for every patient to apply it.

It should be noted some limitations associated with the features of the anatomical nature in the venous bed, as well as the diameter of the nodes. Trophic changes on the skin, presence of thrombophlebitis are also considered problematic.

Therapeutic procedures are carried out on an outpatient basis. In the process, cuts and general anesthesia are not used.

In the venous lumen under ultrasound control , a special disposable radiofrequency catheter is inserted. After the conductor is located on the required length of the altered pathological site, a certain "water feather" is created. It involves the introduction of an anesthetic around the vessel. In this case, the delimitation of the vein from the nearby tissues and local anesthesia is performed. After these manipulations, special equipment is launched - a radio-frequency generator. This apparatus transmits waves to the working site of the endovascular catheter.

During one such inclusion it is possible to process about seven centimeters of a vessel. The procedure continues with a gradual movement of the conductor through the venous passage.

At the conclusion of the session, a sterile bandage is applied to the probe insertion site . Then elastic compression of the limb is made using special bandages or medical jersey.

The patients, who underwent radiofrequency ablation, were mostly positive. Mainly, the procedure assumes a fairly easy rehabilitation period with a short period of use of compression products (two to four days). This allows you to assign procedures in the hot season.

In addition, the technique is not particularly complicated (in comparison with sclerotherapy and laser coagulation), which is due to the presence of a feedback system in the radio frequency generator. Thus, the amount of energy is automatically calculated and selected for each individual impact.
