title: Outcomes of ultrasound-guided foam sclerotherapy for varicose veins of the lower extremities: a single center experience.
abstract: OBJECTIVE
  Ultrasound-guided foam sclerotherapy is increasing in popularity as a method to treat varicose veins of the lower extremities. In 2001, we began using ultrasound-guided foam sclerotherapy to treat varicose veins of the lower extremities. The outcomes of our treatment are described in this study.
  
  
  METHODS
  One hundred four patients underwent ultrasound-guided foam sclerotherapy for 138 extremities over a 5-year period, from January 2004 to December 2008, at Tokyo Women's Medical University Hospital. The outcomes were studied retrospectively using chart review. The average age, sex, and recurrence rates were calculated. At 24 months after treatment, the primary and secondary success rates were analyzed.
  
  
  RESULTS
  The mean age of the patients was 63.2; 30 (22%) were male. Twenty-five (27%) patients had recurrences in 35 (34%) extremities. At 24 months, the primary success rate was 62.2%, and the secondary success rate was 75.8%.
  
  
  CONCLUSIONS
  None of the patients experienced adverse events. The recurrence rates were slightly higher than those of other published data, which may be due to the lower dose of foam used in GSV. In summary, ultrasound-guided foam sclerotherapy can be easily and effectively performed in an outpatient clinical setting. The authors have indicated no significant interest with commercial supporters.
