Lower limb varicose veins are often secondary to greater saphenous vein GSV insufficiency. Technological development has led to the appearance of new minimally invasive treatments, such as endovenous radiofrequency ablation ERFA.

This almost completely eliminates the disadvantages associated with conventional surgery haematomas, scars, inguinal neovascularisation, and a prolonged time off work. Furthermore, it gives a better quality of life, less pain and inflammation than the endolaser. Between January and we have treated limbs with a mean GSV diameter of 6. Clinical and ultrasound follow-up with a prospective register was performed at 1 week, 3, 6, 12 months, and then annually..

Inguinal neovascularisation was present on 0. There was no neuritis, skin burns or deep vein thrombosis.. Las varices de las extremidades inferiores frecuentemente son secundarias a insuficiencia de la vena safena interna VSI.

Chronic venous insufficiency is highly prevalent in Western society. Considering the pathophysiology of chronic venous insufficiency, it is clear that in order to achieve effective and lasting results in treating varicose veins, we must eliminate the venous reflux.

Until recently, the only effective and lasting surgical treatment for truncal varicose veins was ligation of the saphenous-femoral arch and stripping of the GSV. Over the latest decade, technological progress has enabled the development and application of new minimally invasive therapies such as VNUS Closure endovenous radiofrequency ablation RFA and endolaser.

Radiofrequency RF is electromagnetic energy and thus non-ionising. It is composed of electric and magnetic waves that, when in contact with tissue, cause vibration and friction of their atoms, transforming into thermal energy ohmic or resistive heat. The increased temperature generated by RF causes a series of changes to the structure of the treated vein. Thus, the therapeutic objective of RFA is to induce fibrotic occlusion of the treated vein and its subsequent disappearance by atrophy Fig.

Staining with haematoxylin—eosin. Human saphenous vein occluded by fibrosis File Dr C. It was first applied to clinical practice in , receiving approval from the Food and Drug Administration FDA in In recent years, its use has been increasingly spreading throughout most of the developed world.

In addition, its indications have been expanded to venous segments other than the GSV, such as the anterior saphenous vein, the external saphenous vein and the perforating veins. Starting in , various clinical and experimental studies were published demonstrating RFA to be safe and effective in eliminating saphenous vein reflux.

Of still greater importance was the information from the publication of four prospective randomised studies comparing the gold standard of conventional surgery femoral saphenous arch ligation and GSV stripping. The results are described in detail below. The Rautio et al. The most significant differences were between day 5 and day 14 after surgery.

The need for analgesics in the RFA group was 0. Eighty limbs underwent surgery: 44 with RFA and 36 with stripping. During early follow-up four months , complications, recovery time and quality of life variables were compared.

The most significant differences between the groups were recovery time after surgery, with a return to normal activities time of 1.

These differences went away over time, as was to be expected. The impact on clinical and haemodynamic results was once again compared in this patient sample at one year and at two years. Hinchcliffe et al. The results demonstrated the superiority of RFA for the majority of studied variables: shorter surgical time From the technical and technological standpoint, there are significant differences between them that have been shown at the experimental level in two studies by Schmedt et al.

Overall technical success at one month was A greater number of complications were reported for EVL, Some 2. The recanalisation rate was somewhat greater for RFA, 5. The rate of extension of the thrombus into the common femoral vein was 0. Gale et al. Therefore, EVL was more effective than ClosurePlus but in exchange for a higher rate of ecchymosis and discomfort during the perioperative period. In , Almeida et al. The primary objectives were postoperative pain, ecchymosis, swelling and complications from the procedure.

The study concluded that: 1 RFA is significantly superior to EVL in terms of post-operative recovery and quality of life parameters and, 2 complications were significantly more prevalent in the EVL group In , Shepherd et al.

They treated 87 limbs in a study designed to assess the differences in short-term pain and swelling. The results were comparable to the studies described above, although it analysed separately unilateral and bilateral procedures.

In summary, with the data currently available, we can conclude that RFA achieves similar results to EVL, although with clearly less pain, ecchymosis and haematomas, as well as providing better short-term quality of life. Endovenous radiofrequency ablation requires a generator and a bipolar catheter.

The characteristics of each are listed below. The Plus model catheter Fig. In addition, it has a temperature sensor on that tip, which transmits information to the generator concerning various treatment parameters temperature, impedance and power.

The opening of the catheter allows for the transmission of RF energy from the electrodes and through the venous wall, which is known as resistive heating, that is, heat is not generated at the catheter tip but in the vein wall. The central lumen of the catheter requires continuous flushing with heparinised saline solution to minimise clotting on the tip. It allows for the passage of a 0. There are two catheters depending on the size of the vein: 5F 1.

Despite the positive clinical results reported with the Plus system, the procedure has a number of disadvantages, mainly the slowness, and a certain degree of variability in the speed of ablation. It was also frequently necessary to extract the catheter during the procedure so as to clean the clot that formed on the electrodes. Various experimental and clinical research studies 31,32 with different designs have led to the development of the new FAST catheter, which has improved the efficacy and reduced the time of ablation considerably.

It won FDA approval in August and has been marketed since the first quarter of This next-generation catheter has a 7-cm long therapeutic segment on the tip and a lubricious jacket to facilitate guidance and minimise clotting on the heating segment Fig.

It is a very accurate temperature control system regulated by a feedback mechanism thanks to a temperature sensor near the catheter tip.

The RFG2 generator Fig. It thus provides transmural heating of the venous wall while limiting the heating up of the surrounding tissue.

The control unit display shows the real time power, temperature and treatment cycles. The catheter has white spacing markers every 6. Pullback during ablation is segmental, unlike ClosurePlus, which was continuous and therefore subject to variability. The section of vein closest to the saphenous-femoral junction requires two treatment cycles according to a well-established protocol.

Like ClosurePlus, it allows for the use of a 0. This is a completely ultrasound-assisted procedure. Marking should be performed before the operation using Doppler ultrasound, from groin to ankle, highlighting winding sections, ectasia areas, incompetent perforating veins and varicose packages. The procedure absolutely requires the use of tumescent local anaesthesia, that is, through an ultrasound-guided injection of Klein's Solution lidocaine, adrenaline, bicarbonate and saline solution at the perivenous level in the split of the superficial aponeurosis.

Tumescent anaesthesia has a threefold purpose: 1 analgesia, 2 protection for the skin and surrounding structures against heat and, 3 promotion of vein collapse. Access to the GSV varies and may be surgical through a mini-incision or percutaneous Fig.

The latter is performed using the Seldinger technique. To prevent recurrence, it is essential to occlude birth of collateral veins with retrograde flow.

Therefore, the tip of the catheter should be placed near the epigastric vein and never more than 2 cm from the saphenous-femoral junction. During energy emission, applying external pressure on the heating segment and placing the patient in the Trendelemburg position is recommended.

After completing the procedure, the treated segment should be monitored by ultrasound, as well as the correct permeability of the common femoral vein Fig. Despite its low frequency, thrombotic complication must be ruled out by monitoring via Doppler ultrasound during the first post-operative days. Percutaneous access to the infragenicular saphenous vein for catheter insertion. Typical ultrasound pattern after endovenous radiofrequency ablation File Dr C.

The mean age was 57 years range 18—84 and mean GSV diameter was 6. All data was collected prospectively. Seventy-one percent of procedures were performed exclusively under tumescent anaesthesia, with immediate return to normal activity.

An inguinal surgical approach was not performed in None of the patients suffered burns, neuritis or deep vein thrombosis. Heat-induced thrombosis, i.

This is a benign condition associated with thermal ablation techniques. Clinical and ultrasound follow-up was performed on our patients during the first week and at one month, three months, six months, one year and annually.

    Varicose veins are swollen, twisted veins that you can see just under the skin.
