title: Endovenous radiofrequency ablation: no value in short-term duplex ultrasound follow-up.
abstract: BACKGROUND
  Endogenous radiofrequency ablation (RFA) is a proven treatment for varicose veins that has equal efficacy to surgical stripping. It offers the benefit of reduced post operative pain and wound infection and quicker return to work.
  
  
  OBJECTIVE
  To carry out a clinical audit of patients undergoing RFA to monitor outcomes, complication rates, follow-up sclerotherapy and to assess the need for post-operative duplex scan.
  
  
  METHODS
  A retrospective analysis was performed of 174 procedures carried out from January 2011 to March 2012. Patients were pre-assessed with history, physical exam and duplex ultrasound. They were followed up at 3 months with same. CEAP classification was applied to check for post-operative improvement.
  
  
  RESULTS
  174 procedures, including 165 great saphenous vein and 9 short saphenous vein ablations were carried out on 154 patients. The duplex occlusion rate at 3 months was 99 %. 141 patients (81 %) showed a reduction in CEAP score with average CEAP decreasing from 2.37 to 0.96. Overall the complication rate was low at 7 %. Paraesthesia was the most common complication with 7 cases (4 %). There were no DVTs. 45.4 % of patients went on to have follow-up sclerotherapy for venous flares.
  
  
  CONCLUSIONS
  RFA is a safe and effective treatment for varicose veins. There is no benefit in performing routine short term follow-up duplex scan due to the high occlusion rates.
