Combining Proximal Foam Sclerotherapy and Distal Endovenous Laser Ablation for Recurrent Varicose Vein Treatment.

BACKGROUND: Recurrent varicose veins with neovascularization are a common clinical problem. Although endovenous laser ablation (EVLA) has become the standard treatment modality to treat truncal veins, additional sclerotherapy is required to treat newly formed tortuous veins. A novel laser fiber with an injection channel (nLF) allows for such simultaneous proximal sclerotherapy and offers a potentially more effective treatment option. OBJECTIVE: The aim of this study was to present our experience using the nLF for combined EVLA and sclerotherapy treatment of symptomatic recurrent varicose veins. MATERIALS AND METHODS: A retrospective single-center cohort study analyzed the outcomes of all patients with symptomatic recurrent varicose veins, treated with an nLF between September 2020 and August 2022. RESULTS: In total, 28 combined EVLA/sclerotherapy procedures performed with the nLF in 26 patients were analyzed. In all cases, neovascularizations were treated by sclerotherapy through the nLF catheter, followed by laser ablation of the remaining truncal veins. All follow-up ultrasound examinations showed persistent complete occlusion of the treated truncal veins and neovascularizations. No clinically relevant complications were observed. CONCLUSION: Combining proximal foam sclerotherapy and distal EVLA using an nLF for the treatment of symptomatic recurrent varicose veins is safe and effective.
