title: Initial experience in endovenous laser ablation (EVLA) of varicose veins due to small saphenous vein reflux.
abstract: OBJECTIVE
  Conventional surgery for varicose veins due to small saphenous reflux is associated with high recurrence rates (up to 50%), many resulting from inadequate surgery. This prospective audit examines the safety and efficacy of EVLA in the treatment of this.
  
  
  METHODS
  65 patients (68 limbs) with varicosities due to primary or recurrent sapheno-popliteal junction (SPJ) and small saphenous vein (SSV) reflux underwent out-patient EVLA (810 nm diode laser). The SSV was ablated from mid-calf to the SPJ. Symptomatic improvement (Aberdeen Varicose Vein Severity Score [AVVSS]), time to return to normal activity, post-EVLA analgesic requirements, and complications were recorded.
  
  
  RESULTS
  Duplex ultrasound follow-up (median 6-months) confirmed abolition of SPJ/SSV reflux in all limbs following a median total laser energy delivery of 1131J (IQR 928-1364) at an energy density of 66.3 Joules/cm (IQR 54.2-71.6). AVVSS improved from 15.4 (IQR 11.8-19.7) to 4.6 (IQR 3.2-6.7) at three months (p<0.001). Median analgesia requirement was 3 days (23% [15/65] patients required none) and the median time to normal activity was 0 (0-4) days (65% [42/65] returning to normal daily activity immediately). There were no instances of skin burns or DVT but 3 patients (4.4%) developed transient cutaneous numbness (sural nerve). 98% (64/65) patients would undergo EVLT again.
  
  
  CONCLUSIONS
  EVLA abolished SPJ/SSV reflux in all limbs. This is likely to be more effective than conventional surgery, although long-term follow up is required. Data from a randomised control trial would be desirable.
