Ablation by endovascular radio frequency (VNUS Closure®)

The Institut Vascular García-Madrid with a great deal of experience and a team-working method offers you the most innovative techniques for the diagnosis and treatment of varicose veins.


What are varicose veins?


Varicose veins are dilated and winding veins that don’t work correctly anymore, generally affecting the inferior extremities, and are more frequent in women (80%). They can appear as an aesthetic variation or can also be accompanied by pain, heaviness, fatigue, and an increase in the volume of the extremity.
There are different kinds of varicose veins: telangiectasias or spider veins, which can be red, purple or blue and correspond with dilation of the most superficial venous plexus, reticular that form from the collecting veins of the greatest magnitude and troncular for showing-off of the main torso (saphenous veins).


What complications can they present?

If the varicose veins aren’t treated in time, they keep growing in size until they create complications such as: varicothrombosis, varicorrhage (bleeding) and trophic skin disorders with the appearance of ulcers.


How can they be diagnosed?

To make a good differential diagnosis it is necessary to do an exhaustive study through an examination factoring in family history and risk factors, as well as a specific physical examination. Also, a blood test of the vein system through colour eco-Doppler is essential.


What methods are there for the treatment of varicose veins?

There is not only one treatment; every patient should follow treatment on an individual basis. To get the best results the correct combination of various techniques and the understanding of the problem are necessary, depending on the pattern of vein showing of each patient. 


We can emphasize the newest technique derived from the advances in technology:
  • Ablation by endovascular radio frequency (VNUS Closure). pioneer in the treatment of varicose veins through endovascular radio frequency, which today constitutes a minimally invasive procedure, outpatient, innovative and an alternative to conventional surgery and endolaser.

    Radio frequency is based on the application of controlled energy in the form of heat through a two-poled catheter. Differing from conventional surgery, the radio frequency avoids inguinal incisions and bruises to the muscle, and also preserves the physiological inguinal drainage and reduces the formation of new veins. The procedure itself is very similar to the laser treatment, although it acts in a completely different way. The laser causes the blood to clot and changes the interior layer of the vein (thrombotic obstruction), whereas the radio frequency uses a much lower temperature and being constantly regulated allows it to produce a change (denaturalization) of the proteins from the venous wall which induces the fibrotic blockage effect.    

    The patient goes home once the session ends and can do normal activities without having to rest. The results are excellent and its effectiveness has been widely demonstrated.


Other techniques from the normal therapeutic list are:
  • Liquid sclerosis or with microfoam consists of injecting a clarifying product whose aim is to make the varicose veins and telangiectasias disappear. It is a painless outpatient procedure.
  • Conventional surgery and microflabectomy. This consists of removing the varicose veins.
