Catheter foam sclerotherapy of refluxing great saphenous vein combined with preterminal saphenous interruption and phlebectomy: 1-year clinical and ultrasound outcomes

Objectives To assess the efficacy and safety of catheter foam sclerotherapy of refluxing great saphenous vein (GSV) after preterminal saphenous interruption and phlebectomy. Patients and methods We describe the results of the first 80 patients who fulfilled the inclusion criteria. The study endpoints were procedural technical success, 1-year GSV recanalization by duplex, and its relation to clinical varicose veins' recurrence and disease severity by comparing the presclerotherapy venous clinical severity score with the postsclerotherapy values. Results Technical success was 100%. After 1 year, venous clinical severity score improved from 7.3±2.2 to 2.5±0.3 (P
