Objectives: To assess the efficacy and safety of ultrasonic guided foam sclerotherapy (UGFS) with a 
saphenous trunk varicose vein 
Methods: One hundred and seventy cases with long saphenous (LSV) varicose vein underwent foam 
sclerotherapy. Patients were evaluated using Venous Clinical Severity Score (VCSS) and duplex pre

(LSV) reflux underwent foam sclerotherapy 102 females (60%), 68 males (40%). The mean age of patients was 
38.8 years, SD (11.35). Two weeks after the first treatment session, the success rate was 93.5%. The failure 
rate was 6.5%. The complications detected in 23 cases 2 weeks after the first treatment session and included
