1 Three-year European follow-up of endovenous radiofrequency-powered segmental thermal ablation of the great saphenous vein with or without treatment of calf varicosities  Thomas M. Proebstle, MD, PhD, Jens Alm, MD, Oliver Göckeritz, MD, Christian Wenzel, MD, Thomas Noppeney, MD, Christian Lebard, MD, Olivier Pichot, MD, Carmine Sessa, MD, Denis Creton, MD  Journal of Vascular Surgery  Volume 54, Issue 1, Pages (July 2011) DOI: /j.jvs Copyright © 2011 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Diameters of 254 great saphenous veins (GSV) before study treatment and its later fibrotic stages during follow-up as measured 3 cm below the saphenofemoral junction. Numbers of evaluable GSVs decreased to 112 at 36 months. Data are given as average ± standard error (green) and standard deviation (light blue) as well as median (horizontal line) with 25% and 75% quantiles (red box).

3 Fig 2 A, Time-to-flow analysis shows any flow within the treated vein, according to Kaplan-Meier methods. Numbers in the lower line indicate legs at risk at a given follow-up time. B, Time-to-reflux analysis, indicating any reflux within the treated vein, regardless if clinically relevant or not, is shown according to the method of Kaplan and Meier. Numbers in the lower line indicate legs at risk at a given follow-up time. Standard errors were <0.1 at all times.

B, Time course of the distribution of CEAP stages C2, C3, and C4 after study treatment.

5 Fig 4 Time course of the Venous Clinical Severity Score (VCSS) during follow-up in 256 legs monitored for 36 months. Data are given as average ± standard error (green) and standard deviation (light blue) as well as median (horizontal line) with 25% and 75% quantiles (red box).
