Laser Treatment (EVLT) VS Radiofrequency Ablation (RFA)
There are two “minimally invasive” techniques for varicose vein treatment: Radiofrequency ablation (RFA) and endovenous laser therapy (EVLT).” Most centers offer either laser or radiofrequency ablation. But which is better?
Both techniques are similar, and both are effective ways to treat varicose veins. Both treat venous insufficiency of the large superficial veins by using thermal energy, in the form of laser or radiofrequency energy, to close the blood vessel from the inside.
So how are the treatments different and which one works better?
Radiofrequency ablation targets the vein wall using a radiofrequency wave in 20 second bursts. The collagen of the vein wall is heated which makes the treated vein shrink around the catheter. During the process, the vein actually closes.
Laser treatment also uses a catheter within the vein, but instead of a radiofrequency wave, a laser device is used to target the vein wall. The heating element of the device is quite variable, with frequencies which range from 810 to 1470 nanometers (nm).
So why do many vein clinics use EVLT instead of VNUS closure?
It seems that the main reasons are the cost of the equipment and its operation.
