    Institut Vascular Sala-Panell (Centro Médico Teknon), Barcelona, Spainn.
    Background: Despite adequate treatment of varicose veins, recurrences and primary failures still occur. This article hypothesizes that increasing the dose of radiofrequency ablation (RFA) could improve efficacy through inducing a greater shrinkage of the treated vein.

    Methods: A comparative clinical study of 67 extremities with varicose veins caused by great saphenous vein (GSV) reflux treated with RFA ClosureFAST was conducted. Read More

    Postoperative pain and early quality of life after radiofrequency ablation and mechanochemical endovenous ablation of incompetent great saphenous veins.
    J Vasc Surg 2013 Feb 8;57(2):445-50. Epub 2012 Nov 8.
    Department of Surgery, Rijnstate Hospital, Arnhem, The Netherlands.
    Objective: Thermal ablative techniques of varicose veins carry a risk of heat-related complications, including postoperative pain. Mechanochemical endovenous ablation (MOCA) might avoid these complications and reduce postoperative pain because of the absence of thermal energy. This study evaluated postoperative pain and quality of life after radiofrequency ablation (RFA) and MOCA for great saphenous vein (GSV) incompetence. Read More

    Chronic venous ulcer: minimally invasive treatment of superficial axial and perforator vein reflux speeds healing and reduces recurrence.
    Ann Vasc Surg 2013 Jan 18;27(1):75-83. Epub 2012 Oct 18.
    Division of Vascular Surgery, Minneapolis Heart Institute, Abbott Northwestern Hospital, Minneapolis, MN, USA.
    Background: Chronic venous ulcer (CVU) is common and is responsible for significant health care expenditures worldwide. Compression is the mainstay of treatment, but long-term compliance with this therapy is often inconsistent, particularly in the elderly and infirm. Surgical ablation of axial and perforator reflux has been used as an adjunct to compression to reduce recurrence rates and assist healing. Read More

    Radiofrequency ablation of the great saphenous vein with the ClosureFAST™ procedure: mid-term experience on 400 patients from a single centre.
    Surg Today 2013 Jul 30;43(7):741-4. Epub 2012 Aug 30.
    General and Vascular Surgery Department, Istituto Auxologico Italiano IRCCS, Via Pier Lombardo 22, 20135, Milan, Italy.
    Introduction: Endovascular obliteration of the great saphenous vein (GSV) has been proposed as an alternative to conventional extirpative treatment of varicose veins.

    Materials And Methods: This report reviewed the initial experience with the ClosureFAST™ procedure in 407 legs over a one-year period. Occlusion of the GSV was seen on 98 % of completion scans and in all patients within 1 week of the procedure. Read More

    Radiofrequency-induced thermal therapy: results of a European multicentre study of resistive ablation of incompetent truncal varicose veins.
    Phlebology 2013 Feb 3;28(1):38-46. Epub 2012 Aug 3.
    Queens Medical Centre - Vascular Surgery, Nottingham, UK.
    Objectives: To investigate the effectiveness of bipolar radiofrequency-induced thermal therapy (RFITT) in a multicentre non-randomized study.

    Methods: Some 672 incompetent saphenous veins (85% great saphenous varicose vein, 15% short saphenous vein) in 462 patients (56.5% CEAP [clinical, aetiological, anatomical and pathological elements] class 3 or worse) were treated in eight European centres. Read More

    Short-term outcome analysis of radiofrequency ablation using ClosurePlus vs ClosureFast catheters in the treatment of incompetent great saphenous vein.
    J Vasc Surg 2012 Apr 2;55(4):1048-51. Epub 2012 Mar 2.
    Department of Surgery, Division of Vascular Surgery, Maimonides Medical Center, Brooklyn, NY, USA.
    Background: Radiofrequency ablation (RFA) is a widely accepted alternative to high ligation with proximal stripping of the great saphenous vein (GSV) in the treatment of lower extremity venous insufficiency. This study compared short-term outcomes of two generations of (VNUS Closure) RFA catheters, ClosurePlus (CP) and ClosureFast (CF).

    Methods: From February 2005 to April 2009, a total of 667 consecutive office-based RFA procedures were performed in our institution. Read More

    Benefit of a single dose of preoperative antibiotic on surgical site infection in varicose vein surgery.
    Ann Vasc Surg 2012 Jul 8;26(5):612-9. Epub 2012 Feb 8.
    Department of Surgery, Mercy Jewish Hospital, Cincinnati, OH, USA.
    Background: Ligation and division of the saphenofemoral junction (L/D SFJ) can protect against the danger of venous thromboembolism (VTE) associated with greater saphenous vein (GSV) radiofrequency ablation (RFA). Although this procedure is regarded as clean from an infection standpoint, surgical site infection (SSI) can offset its thromboembolic benefit. We questioned whether SSI associated with L/D SFJ could be minimized by a single preoperative dose of antibiotic. Read More

    Radiofrequency induced thermotherapy (RFITT) of varicose veins compared to endovenous laser treatment (EVLT): a non-randomized prospective study concentrating on occlusion rates, side-effects and clinical outcome.
    Eur J Dermatol 2011 Nov-Dec;21(6):945-51
    Kurpark Center of Dermatology, König-Karl-Str. 28, 70372 Stuttgart, Germany.
    Background: Radiofrequency obliteration (RFO) and endovenous laser treatment (EVLT) are established techniques in varicose therapy. A novel bipolar RFO technique - Radiofrequency Induced Thermotherapy (RFITT) - was introduced in 2007. Comparative studies of RFITT and EVLT with one year follow-up are missing. Read More

    [New advances in the treatment of varicose veins: endovenous radiofrequency VNUS Closure®].
    Cir Esp 2011 Aug-Sep;89(7):420-6. Epub 2011 Jul 1.
    Angiología, Cirugía Vascular y Endovascular, Institut Vascular Sala-Planell (Centro Médico Teknon), Barcelona, España.
    Unlabelled: Lower limb varicose veins are often secondary to greater saphenous vein (GSV) insufficiency. Technological development has led to the appearance of new minimally invasive treatments, such as endovenous radiofrequency ablation (ERFA). This almost completely eliminates the disadvantages associated with conventional surgery (haematomas, scars, inguinal neovascularisation, and a prolonged time off work). Read More
