Complete guide about Radiofrequency Ablation for
Varicose veins:
25% people of any country suffer from varicose veins. A frequent disease that
can be treated in less than an hour thanks to radiofrequency. Varicose
veins are due to abnormal dilatation of a vein that deforms, lengthens and
becomes tortuous. This is a chronic disease. Women are more often affected
than men.
What promotes varicose veins?
 Heredity is also an important part of venous disease.
 Other criteria such as pregnancy, overweight, exposure to heat, standing
work and a sedentary lifestyle may favor varicose veins.
Varicose vein removal by Radio Frequency:
Radiofrequency is defined as a radio-electric wave whose frequency is less
than 300 Giga-Hertz, that is a wavelength greater than 1 mm. In medicine, it
has long had applications in many areas: removal of tumors, liver in particular,
treatment of the soft palate for snoring, and more recently treatment of
certain disorders of the heart rhythm. Its mode of action is destruction by heat:
the waves delivered cause a molecular agitation of the nearby tissues, which
induces a significant increase of the temperature in these tissues.
For varicose veins , the target tissue is the venous wall , and the first use of
radiofrequency in this application dates from 2000. The veins involved in this
treatment are the saphenous veins. Formerly the saphenous veins were
treated by stripping: the vein was surgically removed, through incisions.
Like the endovenous laser, the RF Ablation for Leg Veins is an endovenous
technique, so the probe must be introduced into the vein to be treated. This is
done through a small introducer, which is a kind of small plastic hose of the
same type as those used for any endovascular treatment, for example for
dilatation of leg arteries or for dilatation of arteries coronary for the heart.
For Radiofrequency Ablation Varicose Veins, a radiofrequency probe is
required which measures only a little more than 1 mm in diameter. The
necessary introducers are therefore of small caliber, and they measure 10 cm
long; they are placed in the vein after venipuncture with the needle at the level
of the leg, under local anesthesia . Once the introducer is in place, the probe is
slid into this pipe and mounted in the vein to be treated to the desired level,
under ultrasound control. Once the probe positioned correctly, a local
anesthesia called "tumescence" is performed: injection around the vein to be
treated, a mixture of saline with anesthetic, lidocaine, put in small amounts.
Tumescence isolates the vein from the rest of the tissues, which must be
preserved when the vein is heated; it plays an important role for security. It
also allows better contact of the vein with the probe; it therefore enhances
efficiency. In addition, by the anesthetic effect of tumescence, treatment of
the vein by heat is painless. Tumescence is therefore a very important step,
currently unavoidable, and must be performed under ultrasound guidance for
more precision and safety.
