Endovenous Radiofrequency Ablation (RFA)

Endovenous Radio Frequency Ablation is a minimally invasive, in-office treatment alternative to surgical stripping of the great saphenous vein. Instead of removing the saphenous vein, it is sealed closed in place. The skin is numbed at multiple sites and a radio-frequency catheter is inserted into the damaged vein through a needle stick in the skin. The catheter delivers radiofrequency energy to the vein wall causing it to heat. As the vein warms, it collapses and seals shut. Patients experience very little, if any, discomfort during this non-invasive vein procedure.

Following the procedure, the catheter is removed and a bandage or compression stocking is placed on the treated leg. The patient can return to work the same day after treatment with minimal restrictions.
