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

Abstract Purpose To prospectively evaluate the feasibility and safety of foam sclerotherapy and ligation (FSL) for outpatients with varicose veins under local anaesthesia. Methods 136 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. Results 146 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. Conclusion FSL is feasible, safe and easily to perform under local anaesthesia for outpatients with varicose veins.
