What is this paper about

This review shows that sclerotherapy—especially ultrasound-guided foam—is an effective, low-burden option for varicose veins, but durability is weaker than thermal ablation or surgery in truncal reflux. The full paper defines where it works best, when adjunctive use is smarter, and which safety risks deserve attention.

Abstract: To map and synthesize the original evidence on sclerotherapy for varicose veins, with emphasis on treatment effectiveness, comparative durability, adjunctive and combined strategies, safety signals, technical determinants, and clinically actionable implications. The review uses 167 references and builds its evidence map from 423 original studies with 3117704 total participants/sample observations (topic-deduplicated ΣN). This scoping review suggests that sclerotherapy, and particularly ultrasound-guided foam sclerotherapy, is a versatile and broadly effective minimally invasive option for varicose veins, delivering high early occlusion and symptom relief across truncal, tributary, recurrent, and ulcer-associated disease, with reports of up to 91% complete occlusion after one to three sessions. However, the dominant signal is that durability for truncal great saphenous reflux is more limited than thermal ablation or surgery, with 5-year recanalization around 31.5% after UGFS versus 5.8–6.8% after RFA or EVLA, supporting a treat-as-needed framing and shared decision-making around retreatment expectations. Safety signals indicate that serious neurologic, arterial, and thromboembolic events are uncommon but warrant disciplined foam volume, ultrasound guidance, and risk stratification. The principal uncertainty concerns long-term comparative durability and standardization of foam technique, and future adequately powered trials with harmonized 5- to 10-year endpoints are needed to clarify optimal positioning of sclerotherapy within combined and stand-alone treatment pathways.
