Treatment of Primary Varicose Veins by Endovenous Obliteration with the VNUS Closure System: Results of a Prospective Multicentre Study

Radiofrequency saphenous vein obliteration improves the symptoms of varicose veins. The reflux-free rates in the treated veins remain constant over a 3 year follow-up period. There is no difference in clinical outcomes between the TO and the PO limbs, suggesting clinical effectiveness of the PO category. Greater than a 5 cm open segment in treated veins poses a risk of recurrence.
