Endovenous radiofrequency ablation (RFA) of the veins of the lower extremities
Radiofrequency ablation (RFA) more than 10 years is practiced in Western countries as a method of rapid and reliable treatment of veins affected by varicose veins. Initially, RFA was used in cardiac surgery to treat arrhythmia. Operation with the use of radio frequency is the most effective method of treating varicose veins, which has great advantages over other methods. Radiofrequency ablation (RFA) of the veins of the lower extremities in Moscow appeared relatively recently. However, 5 years of practice have shown that this is the most painless and safe endovenous method of treating varicose veins, which has a tremendous effect.
Радиочастотная абляция (РЧА Venefit™): что это такое
Radiofrequency ablation is an intravascular thermal action on the vein walls by radiofrequency radiation to close the lumen of a damaged vessel. Simply put, radiofrequency ablation (RFA) is a kind of "brewing" of a vessel with its switching off from the total blood flow. Otherwise, the RFA method is called the radiofrequency obliteration of Covidien or formerly called VNUS Closure. The essence of the method lies in the management of a varicose vein of a radiofrequency catheter and a step-by-step heat treatment of a site affected by varicose veins.
Radiofrequency ablation allows:
- скорректировать косметический дефект (устранить неприятную картину испещренных варикозными венами ног);
- eliminate puffiness, discomfort and pain in the lower limbs, accompanying varicose veins;
- Exclude the possibility of sudden death from phlebotrombosis, thrombophlebitis and pulmonary embolism (PE).
Radiofrequency ablation (RFA) - Wikipedia says that ...
The RFA method is more appropriate for treating both small and large veins with a lumen diameter of more than 15 mm. If the thickness of the vein is no more than 3 mm, then it is more appropriate to use laser obliteration of the veins, since the light guide is slightly thinner than the radio-frequency catheter.
Radiofrequency ablation (RFA) of veins is technically difficult to perform on vessels with a pronounced flexure or special structure. However, on the small and large subcutaneous veins, which are most often subjected to radiofrequency "brewing", serious bends that prevent the passage of the catheter are extremely rare.
Advantages of radiofrequency ablation
RFA has a number of advantages in comparison with other radical methods of treatment of varicose disease:
- The highest efficiency achieved by precision of impact
- possibility of outpatient treatment
- The painlessness of the method and the easy tolerability of the procedure
- cosmetic effect (no incisions and seams)
- The absence of the possibility of medical error in determining the settings of radio frequency exposure
- The possibility of performing surgery in complicated cases with trophic ulcers and induration of the skin
- short recovery period without serious lifestyle restrictions
- absence of negative manifestations after the procedure (hematoma, paresthesia, neuropathy)
- The possibility of combining RFA with other treatments to maximize the effect
- absence of complications
Preparing for RFA
Radiofrequency ablation (RFA) of the veins of the lower extremities is performed on an outpatient basis, and only a few studies are needed before the procedure. Standard preoperative preparation includes:
- general blood analysis
- general urine analysis
- biochemical blood test
- исследование на сифилис, ВИЧ, гепатиты «В» и «С»
- ECG with the conclusion of the therapist
Immediately before the procedure, the doctor determines the length of the varicose veins of the trunk vein on which the radiofrequency ablation (RFA) will be performed. The cost of the procedure is discussed with the patient during the initial consultation, after making a decision on the application of this technique.
Before carrying out the radio-frequency exposure, the patient should shave the hair on his legs and acquire a special compression knitwear. The patient should not stop taking drugs that are prescribed to him by the course of treatment. There is no need for fasting. No additional medications are prescribed before the operation.
Important: on the day of surgery, the patient can not get behind the wheel of the car!
Carrying out the procedure of radiofrequency ablation
The entire procedure is controlled by duplex ultrasound scanning. The patient in the standing position is labeled with a varicose vein. Further local anesthesia is performed. In this case, almost complete anesthesia is achieved. Delimitation of the vein from nearby tissues is due to tumescent anesthesia - the "water cushion".
After the disinfecting treatment, a puncture of the lower segment of the damaged varicose vein is performed and a catheter is inserted, with the help of which the radiofrequency ablation (RFA) of the veins of the lower extremities will be performed. The price for the procedure is slightly increased due to the use of a disposable catheter. The catheter moves along the vein to the upper segment, that is, to the point where the vein enters the deep venous system. At the end of the catheter there is an RF element of length 7 cm, which will transmit high frequency waves. Next, the generator is started, during 20 seconds, RF waves are processed by this section. Radiofrequency ablation (RFA) of the lower extremity occurs in stages. Using the marks on the RF catheter, the RFA conducting specialist pulls out the catheter for 7 cm and starts the generator again. It should be noted that the device works in automatic mode, independently adjusting the level of power of influence depending on the temperature inside the vein. The duration of exposure is also determined automatically. At the same time, there is no possibility of influence of the "human factor", since the doctor follows only the advancement of the catheter through the vein and does not determine the settings. Everything goes in automatic mode.
Так проводится радиочастотная абляция (РЧА) вен нижних конечностей. Видео, демонстрирующие ход этой операции, доказывают сравнительную простоту данного метода. При этом вся операция длится около 30-40 минут. По окончании процедуры больной сразу надевает компрессионный трикотаж. В течение нескольких недель на месте проблемной вены формируется соединительнотканный тяж.
In almost all cases, RFA is supplemented with a mini varlebectomy according to Varadi or sclerotherapy of inflow (superficial) veins. The question of the application of this or that additional method of treatment is decided by the specialist who will conduct radiofrequency ablation (RFA). The price is largely due to the volume of radio-frequency exposure and the choice of an additional method for achieving maximum efficiency. External changes occur immediately after radiofrequency ablation (RFA) of the veins of the lower extremities has been performed. Photos before and after the procedure clearly demonstrate the effectiveness of this method of treatment.
Rehabilitation after radiofrequency ablation
Rehabilitation after RFA is rather short and lasts 1-2 weeks, to fix the effect in this period, the patient must wear a compression knitwear during the daytime. After other methods, the restoration continues for 2 months or more. Short-term recovery period is another advantage over other methods of treatment of varicose veins.
The first few days after the procedure, you need to limit the physical load on your legs. Do not recommend exercise in gymnastics, aerobics and exercise bike. However, the passivity of the patient is also not welcome. Daily hour walks are needed on foot. The patient is not desirable to sit for long, you need to stand on your feet as much as possible. 3 weeks person who has undergone radiofrequency ablation, should not visit the sauna and sauna. In principle, there are no other limitations after the radiofrequency effect on the veins.
Radiofrequency ablation (RFA) of veins, contraindications
The technique of radiofrequency ablation is not applied in the following cases:
- pregnancy and lactation after childbirth;
- signs of acute deep vein thrombosis;
- presence of a history of thrombosis;
- marked signs of atherosclerosis of the arteries of the lower limbs;
- impossibility to wear compression knitwear;
- a relative contraindication is the presence in the places of targeted punctures of inflamed or suppurated foci of skin infection.
Only the doctor, based on the studies and data of the anamnesis, decides on the choice of the method of treatment. Absence of contraindications and sufficient advantages of the technique incline to the patient to undergo radiofrequency ablation (RFA) of the veins. The feedback of people to whom RFA has been assigned confirm the safety and painlessness of the method.
Radiofrequency ablation (RFA) of the veins of the lower extremities, complications
The RFA method is an automated process that excludes excessive effects on the vein and through perforation. American and European phlebologists believe that the safest method of treating varicose veins at the moment is radiofrequency ablation (RFA). Photos of patients after the procedure confirm the absence of swelling and bruising. There are no such painful sensations both during the RFA and after it.
The only complication that occurred during the development of this technique was deep vein thrombosis. However, such a serious complication was extremely rare. Different sources estimate the risk of thrombosis in 0,1-2%. During the entire 10-year history of the use of radiofrequency ablation, only a few cases of thrombosis or pulmonary thromboembolism have been recorded worldwide.
In order to avoid the formation of thrombi, the attending physician can prescribe in preventive dosages low molecular weight heparins (clexane or fractiparin) from the day when the radiofrequency ablation (RFA) of the veins of the lower extremities is performed. The responses left by patients only occasionally indicate some discomfort. Unpleasant sensations are weakly expressed and quickly pass.
Effectiveness of radiofrequency ablation of veins
Although radiofrequency ablation (RFA) of the veins of the lower limbs has been recognized as the most effective and qualitative method of treating varicose veins, it does not exclude a possible relapse of the disease. None of the modern methods will not provide a complete cure for chronic venous insufficiency. However, the development of relapse after radiofrequency "brewing" of the main veins is almost impossible today.
Patients who received RF Ablation (RFA), whose reviews are posted on the Internet and on our website, are pleased with the results of the operation. The patients note that their way of life and the motor regime practically did not change during the rehabilitation period, and this is very important in our time. Radiofrequency ablation (RFA) of veins, the price of which is quite affordable, is the most effective, safe and fastest way to treat varicose worldwide. Highly qualified personnel of the clinic and high-quality equipment for RFA are the guarantor of an excellent result.
Reviews of the RFA procedure conducted in the "Medical Innovative Phlebological Center"
Response of our patient about RFA procedure: Arina, 26 years, Kashira city.
I want to share my experience about the treatment of my varicose veins by radiofrequency ablation. Obvious signs of varicose have appeared in me for years with 20. On my mother's line all women suffered from this misfortune. And although my mother's legs looked terrible, she never felt pain, and therefore did not consult a doctor. At me very quickly there was a sensation, that to legs or foots the huge stones are adhered. To the heaviness in the legs was added and pain. Sometimes she did not sleep at night, not knowing how to lie down, so that at least a little easier. I would like to extend the words of gratitude to the specialists of your clinic. I was operated on by the radiofrequency method of the vein on both legs. The operation was completely painless. How I rejoiced to see my legs right after the operation: the huge thickness of the bulging veins literally disappeared in front of my eyes. In the first couple of days there was some unpleasant sensation in the legs, but even this is hardly a pain. I continue the maintenance treatment with medications and will be shown for follow-up visits to my doctor. Arina, 26 years old.
Response of our patient about RFA procedure: Elena, 45 years, Moscow.
I 45 years, my whole life with vacation breaks and the decree worked as a salesman. Of course, in the evenings after work my legs became very tired. Gradually began to appear edema and vascular asterisks. She did not go to doctors, she hoped foolishly for a chance. But with the years it got worse. There were terrible blue veins of veins with terrible knots. A friend who was treated in your clinic and was satisfied with the result of the treatment, advised me to contact you. After putting all the tests and examining my veins, I was assigned RFA. At first I was very afraid, because, as I understood, the veins would simply be burned. But the doctor calmed me and convinced me that this is the most painless method. In addition, I have heart problems, I did not really want to do vein operations under general anesthesia, and with RFA do usual anesthesia. In general, all my fears were in vain, an hour and a half after the RFA, I was already at home. Gone is not only the drawing pain and heaviness in my legs, now I can not hide my legs under a long skirt and tight pantyhose. I express my gratitude to all employees of the clinic. Thank you and bow to you with all my heart. Elena, 45 years old.
