Original ResearchFeasibility and safety of foam sclerotherapy followed by a multiple subcutaneously interrupt ligation under local anaesthesia for outpatients with varicose veins

•A multiple interrupt ligation after foam sclerotherapy for varicose veins (FSL) is feasible and effective.•This FSL procedure can be performed as a day surgery.•The FSL may warrant a good closure of treated varicose veins and can minimize the risk of superficial venous thrombosis.

PurposeTo prospectively evaluate the feasibility and safety of foam sclerotherapy and ligation (FSL) for outpatients with varicose veins under local anaesthesia.Methods136 outpatients with varicose veins who were unwilling to be hospitalized underwent FSL. FSL is a technique in which the dilated varicose veins were ligated subcutaneously after foam sclerotherapy with an absorbable suture. Patients were reviewed at 1, 3, 6 and 12 months after FSL. Pain scores were recorded after FSL. The revised venous clinical severity scorer (rVCSS) and clinical, etiological, anatomical, and pathological classification (CEAP) were used to evaluate the improvement at 3 months after treatment.Results146 limbs in 136 outpatients with varicose veins were managed with FSL. The pain scores decreased following FSL, CEAP classification score, the rVCSS values improved 3 months postintervention. No significant postoperative complications were observed on follow-up.ConclusionFSL is feasible, safe and easily to perform under local anaesthesia for outpatients with varicose veins.
