HILLER, HEINZ  y  ULLOA, JORGE HERNANDO. Preliminary results of the safety and efficacy with a hybrid treatment of insufficiency of the great saphenous vein. CES Med. [online]. 2015, vol.29, n.2, pp.191-198. ISSN 0120-8705.

ABSTRACT Background: Treating the insufficiency of the Greater saphenous vein (GSV), using radiofrequency (RF) and LASER ablation have been associated to neuralgia and other complications due to the extension of the thermal injury. Foam sclerotherapy opened a new trend in the treatment of larger veins, reaching superficial varicosities, but the treatment of the GSV, raises the possibility of a quick reopening of the saphenofemoral junction (SFJ). Our group developed an approach that merges the benefits of thermal injury and foam sclerotherapy. Methods: 87 patients classified as C2-C4 (CEAP classification), 73 female, mean age: 58.4 with incompetence and dilatation of GSV where included in this study. Our Hybrid procedure was performed using ultrasound guided percutaneous access of GSV with a new short RF catheter (VNUS Closure FAST) distal to the SFJ under local anaesthesia. Thermal occlusion of the saphenofemoral junction (SFJ) and GSV subjacent segment was achieved. Just before retrieving the device, we injected 8cc of 1 % Lapidium Chloride foam using physiological gas. Duplex ultrasound was carried out to assess GSV and SFJ occlusion; follow-up was at completed 6 months. Results: 83 patients completed the follow-up period. 78 patients had their GSV and SFJ occluded at 6 months demonstrated by duplex ultrasound and 5 required a second dose of foam sclerotherapy. Four patients were lost during follow-up due to change of address. Seven patients reported pain in the groin area immediately after the procedure. There were no major complications. Conclusions: This is a preliminary report of a hybrid procedure that involves use of thermal energy to occlude the SFJ and treat at the same time the GSV and associated varicosities, without the need for further thermal usage of the venous trunk or the use of phlebectomy. This hybrid procedure combines the best of this two techniques, minimizing their disadvantages and potentiating their advantages. The occlusion rate seems promising but further studies should evaluate its effectiveness in time.
