Randomized Controlled Trial Comparative Study
Randomized clinical trial of endovenous laser ablation versus direct and indirect radiofrequency ablation for the treatment of great saphenous varicose veins.
The current treatment strategy for many patients with varicose veins is endovenous thermal ablation. The most common forms of this are endovenous laser ablation (EVLA) and radiofrequency ablation (RFA). However, at present there is no clear consensus on which of these treatments is superior. The objective of this study was to compare EVLA with two forms of RFA: direct RFA (dRFA; radiofrequency-induced thermotherapy) and indirect RFA (iRFA; VNUS ClosureFast™). ⋯ Primary GSV occlusion rates were better after iRFA and EVLA than dRFA. All three interventions were effective in improving the clinical severity of varicose veins at 1 year.
