title: Chronic venous leg ulcers: Effects of foam sclerotherapy on healing and recurrence.
abstract: BACKGROUND
  Ultrasound-guided foam sclerotherapy is a minimally invasive treatment option used for ablation of axial and perforator reflux for chronic venous ulceration. Active ulceration presents a significant health burden in both the primary and secondary care setting. The objective of this study is to determine ulcer healing rates at 24 weeks and 12 months, and ulcer recurrence rates at one year for chronic venous ulcers after ultrasound-guided foam sclerotherapy.
  
  
  METHODS
  Between 2007 and 2012, 54 patients underwent ultrasound-guided foam sclerotherapy for clinical, aetiological, anatomical and pathological C6 ulcers. All patients were followed up clinically, and venous duplex was performed on all legs before and after treatment. A prospectively maintained database was analysed to determine venous truncal occlusion rates, 24-week and 12-month healing and recurrence rates (using Kaplan-Meier survival analysis).
  
  
  RESULTS
  Fifty-seven ulcerated legs, 39 primary and 18 with recurrent superficial venous reflux were analysed. Median time of active ulceration at presentation was 15.2 months (range 5 months to 17 years). At a median follow-up of 2.7 months, 90% (51 legs) achieved full truncal occlusion after one session, 4% (2) short segment occlusion and 5% (3) failed to occlude and one patient died and was lost to follow-up; 13/57 (23%) required a second session of treatment for completion of treatment, recanalisations and to treat perforator disease, 88% (50/57) ulcers healed at a median of 5.3 months (interquartile range 2.9-8.4 months) following their first ultrasound-guided foam sclerotherapy treatment. The 24-week and 12-month estimated healing rates were 53% and 72%, respectively. The estimated 12-month recurrence rate was 9.2%. There were no reported incidences of deep venous thrombosis or neurological symptoms.
  
  
  CONCLUSIONS
  This study affirms the role of ultrasound-guided foam sclerotherapy as a safe and effective option for abolition of superficial reflux.
