OBJECTIVE: Cyanoacrylate closure (CAC) was shown in the recently published VenaSeal Sapheon Closure System vs Radiofrequency Ablation for Incompetent Great Saphenous Veins (VeClose) randomized clinical study to be an effective and noninferior option (in terms of both safety and effectiveness) to radiofrequency ablation (RFA) in the treatment of incompetent great saphenous veins. The objectives of this analysis were to report the efficacy and safety outcomes of the VeClose roll-in (training) group treated with CAC by physicians who had received device use training but had no prior treatment experience with the technique and to compare the outcomes with those from the randomized RFA and CAC groups...

PURPOSE: Cyanoacrylate closure of the great saphenous vein with the VenaSeal™ Closure System is a relatively new modality. Studies have been limited to moderate-sized great saphenous veins and some have mandated postoperative compression stockings. We report the results of a prospective study of cyanoacrylate closure for the treatment of great saphenous vein, small saphenous veins, and/or accessory saphenous veins up to 20 mm in diameter. METHODS: Fifty subjects with symptomatic great saphenous vein, small saphenous veins, and/or accessory saphenous veins incompetence were each treated at a single session...

INTRODUCTION: This is a single-center clinical study for the evaluation of safety, efficacy, and performance of endovenous cyanoacrylate (Sapheon Venaseal Closure System, now Medtronic Medical) for the treatment of great saphenous vein (GSV) reflux. METHODS: Primary outcome measures included the GSV obliteration, with clinical recurrence on follow up as detected by serial clinical and duplex examinations of patients at 1 week, 1 month, 6 months, and 1 year. Venous clinical severity score (VCSS), Aberdeen varicose vein questionnaire (AVVQ), Short Form Health Survey 36 Item (SF-36) questionnaires were used at clinical follow up...

BACKGROUND: Whereas thermal ablation of incompetent saphenous veins is highly effective, all heat-based ablation techniques require the use of perivenous subfascial tumescent anesthesia, involving multiple needle punctures along the course of the target vein. Preliminary evidence suggests that cyanoacrylate embolization (CAE) may be effective in the treatment of incompetent great saphenous veins (GSVs). We report herein early results of a randomized trial of CAE vs radiofrequency ablation (RFA) for the treatment of symptomatic incompetent GSVs...

BACKGROUND: Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux. Newer treatments, especially non-thermal ablation have potential benefits both for patient acceptability and decreased risk of nerve injury. APPROACH: We describe the current non-thermal options available including advantages and disadvantages. Ultrasound guided foam sclerotherapy avoids the risk of nerve injury, however it is not as effective as endothermal ablation...

Consideration of treating incompetent perforating veins remains a conundrum based on scientific evidence available till date. While subfascial endoscopic perforator surgery (SEPS) proved to be a worthy alternative for open surgery, other even less invasive techniques were being introduced by the late nineties of the last century. Percutaneous thermo-ablation techniques are still being used today and seem more effective than non-thermal techniques. However, thermal techniques require anaesthesia and potentially may cause inadvertent damage to surrounding tissues such as nerves...

The constant evolution of endo-venous ablative techniques for varicose veins arises from the need for: better patient's comfort, reduced incidence of side effects, better results at short-, mid- and long-term follow-up, as well as reduction of operating time and technical simplicity. All these goals have been aimed at but so far no new technology has been able to achieve them all or to demonstrate it, furthermore the increase of price must be compensated by a considerable improvement of results and a serious reduction of side effects to be incrementally cost effective...

Less invasive endovenous techniques have been shown to be as effective as open surgery in the treatment of varicose veins. Furthermore, they cause less postoperative bruising and pain and enable early return to normal activities and work. Tumescent anaesthesia is safe and obviates complications of general or spinal anaesthesia. Drawbacks are a steep learning curve and painful administration during treatment. Tumescentless techniques like Clarivein™ or VenaSeal™ Sapheon Closure System are recently under investigation...
