Endoluminal radiofrequency ablation of the long saphenous vein (VNUS closure) -- a minimally invasive management of varicose veins.

This report describes our clinical experience with the VNUS closure. This is a percutaneous catheter-based procedure in which the vein is ablated from within by resistive heating. We performed the UK's first radiofrequency closure without a high tie in March 1999.
