title: Controlled radiofrequency endovenous occlusion using a unique radiofrequency catheter under duplex guidance to eliminate saphenous varicose vein reflux: a 2-year follow-up.
abstract: BACKGROUND
  Saphenous vein reflux is often the underlying anatomic cause of varicose veins. It is necessary to eliminate this reflux originating at the saphenofemoral junction (SFJ) to treat the resultant varicose veins.
  
  
  OBJECTIVE
  To report 2-year follow-up results after closing the incompetent greater saphenous vein starting from its junction (SFJ) with the femoral vein using radiofrequency (RF) endoluminal ablation.
  
  
  METHODS
  One hundred and forty incompetent greater saphenous veins from 120 patients with an incompetent SFJ and large painful varicosities were treated. Patients were evaluated clinically and with duplex ultrasound at 1 week, 6 weeks, 6 months, 12 months, and 24 months to determine treatment efficacy as well as adverse sequelae.
  
  
  RESULTS
  Vein occlusion, defined as the absence of any duplex ultrasound-determined flow, was successfully achieved in 137 of 140 (98%) scanned veins at 1-week follow-up. At the 12-month follow-up, none of the treated patients developed recanalization that was not seen at 6 weeks, with a successful outcome in 90%. At the 24 month follow-up, 19 of 21 patients had complete disappearance of the treated saphenous vein, for a success rate of 90%. Side effects were minimal, and no skin burns or thromboses were observed.
  
  
  CONCLUSIONS
  RF endovenous occlusion allows patients to obtain treatment with the positive attributes of surgery, that is, a single treatment and low rate of recurrent reflux, but without the morbidity, need for general anesthesia, or extensive convalescence associated with vein stripping and ligation surgery. Patient satisfaction was routinely achieved, with 98% of patients indicating a willingness to recommend the RF endovascular procedure to a friend or family member.
