Three-year follow-up analysis of automated microfoam preparation system for great saphenous vein incompetence and varicose veins sclerotherapy treatment

Abstract

BackgroundTo describe the treatment of patients with great saphenous vein (GSV) incompetence and varicose veins (VVs), utilizing an Automated Microfoam Preparation System (AMPS, Varixio®, VB Devices, Barcelona, Spain).MethodsAdults between January and June 2021 were included. The AMPS system was used for foam preparation. Sclerotherapy treatment followed international recommendations. The primary endpoint was GSV closure rate after 36 months.Results164 patients were enrolled. During the 7-day follow-up period, all GSVs showed complete closure, which was maintained at the 1-year mark. No major complications were reported. A cumulative complete GSV recanalization rate of 6.1% and a partial recanalization rate of 26.8% after 36 months were noted. Some patients (9.7%) required additional treatment. A higher BMI was associated with complete recanalization.ConclusionThe AMPS offers an easy-to-use and standardized procedure, potentially enhancing treatment outcomes if compared with manual preparation. Caution is advised when treating obese patients.
