title: [Radiofrequency-powered segmental thermal ablation in chronic venous disorders: A single center experience].
abstract: BACKGROUND
  In the last decade, endovascular radiofrequency obliteration has been used as a safe and feasible method, alternative to conventional vein-stripping surgery.
  
  
  METHODS
  Data were collected from our center between January 2009 and June 2011. Pretreatment examination included lower limb assessment using CEAP classification and VCSS (Vein Clinical Severity Score). Ultrasound examination was performed at first follow-up visit (one week to one month after surgery) and the last-one in September 2011.
  
  
  RESULTS
  The study enrolled 30 patients (33 legs), their mean age was 41.4 ± 10.4 and 76,7% (n=23) were female. Mean follow-up time was 240 days. Treated veins included 32 great saphenous vein above-knee segments, and one small saphenous vein. Only 8% of patients were free of pain before treatment and at last follow-up 61% reported no pain. Edema rate also improved from 52% (before surgery) to 9% at last control. During follow-up, two treated vessels were identified as patent, albeit competent: one a small saphenous vein and the other a segment of a great saphenous vein. Two cases of paresthesias and one of hyperpigmentation were observed at stab avulsion site. The mean VCSS score was 5,6 ±3.11before surgery and 1,4±1.34 at last follow-up.
  
  
  CONCLUSIONS
  Radiofrequency segmental thermal ablation effectively reduced symptoms of venous insufficiency, with a significant reduction at VCSS score, and was a well tolerated and safe method, with few complications.
