Randomized Controlled Trial Comparative StudyProspective randomised comparative study of visual foam sclerotherapy alone or in combination with ultrasound-guided foam sclerotherapy for treatment of superficial venous insufficiency: preliminary report.
The aim of the study is to compare ultrasound-guided foam sclerotherapy (UGFS: injection of foam sclerosant under ultrasound guidance) of the great saphenous vein (GSV) combined with visual foam sclerotherapy (VFS: injection of foam sclerosant under visual control) for varicose tributary veins and VFS alone in the treatment of GSV reflux. ⋯ These results show that UGFS + VFS and VFS are equally effective for the treatment of GSV reflux, despite the lower volume of foam used for VFS alone.
