Ultrasound guided foam sclerotherapy (UGFS) constitutes a valid ablative treatment for superficial vein diseases for the great saphenous vein (GSV), but no standardized protocol for its execution has yet been defined. Different variable factors involved in this procedure influence the final outcome and clinical results. The aim of our study was to analyze the respective influence on efficacy and side effects of three variable factors (foam volume, foam concentration, and contact time between the foam and the endothelium) for UGFS procedures for GSV insufficiency in order to select the best protocol for treatment. A retrospective analysis was made of UGFS procedures (190 patients, 201 legs) performed for GSV insufficiency in our institute from
