Radiofrequency segmental thermal ablation is feasible, safe, and well tolerated.

RSTA showed a high and durable success rate in vein ablation in conjunction with sustained clinical efficacy.

BackgroundThis was a prospective study of radiofrequency segmental thermal ablation (RFA) for the treatment of incompetent varicose great saphenous veins (GSVs). The present report describes long-term follow-up at 5 years.MethodsThe 5-year follow-up of this multicentre European study included assessment of the Venous Clinical Severity Score (VCSS), and GSV occlusion and reflux on duplex imaging.ResultsA total of 225 patients had 295 GSVs treated by RFA, achieving an initial vein occlusion rate of 100 per cent. With 80·0 per cent compliance, Kaplan–Meier analyses showed a GSV occlusion rate of 91·9 per cent and a reflux-free rate of 94·9 per cent at 5 years. Among the 15 GSVs noted with reflux during follow-up, only three showed full recanalization of the GSV at 1 week, 6 months and 3 years. Of the 12 legs with partial recanalization, reflux originated at the saphenofemoral junction in ten, with a mean length of the patent segment of 5·8 (range 3·2–10) cm; only six patients were symptomatic. Mean(s.d.) VCSS scores improved from 3·9(2·1) at baseline to 0·6(1·2), 0·9(1·3) and 1·3(1·7) at 1, 3 and 5 years.ConclusionAt 5 years RFA proved to be an efficient endovenous treatment for incompetent GSVs in terms of sustained clinical and anatomical success for the vast majority of treated patients.

Venous disorders are among the most frequent disease patterns in the Western world. Still at the turn to the 21st century there was no alternative available to the surgical treatment of varicosis. Meanwhile the endoluminal treatment methods have established and have demonstrated their efficiency while having lower side effects in comparison to the traditional treatment, even though conservatively oriented surgeons are still skeptically eyeing these methods. In the US, according to the latest MRG report of 2011, about 95% of all venous surgeries are already done endoluminally. This paper offers an overview of prevailing treatment standards of the most important endoluminal therapy techniques and shows current trends.
