    Abstract:
    BACKGROUND: In the last decade, the microwave ablation catheter specifically for treating lower extremity varicose veins has become popular. However, imited data is available on the efficacy, analysis, and evaluation of endovenous microwave ablation (EMWA) in treating SSV insufficiency. Our objective is to evaluated the feasibility, safety, and 1-year outcomes of EMWA and concomitant foam sclerotherapy of primary small saphenous vein (SSV) insufficiency. METHODS: Our team carried out a single-center, retrospective analysis of 24 patients treated with EMWAand concomitant foam sclerotherapy for primary SSV insufficiency. All operations were performed using a MWA catheter and polidocanol for the trunk and branches of the SSV, respectively. The SSV occlusion rate was assessed at the 6- and 12-month follow-up examinations using duplex ultrasound. Secondary outcomes included the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) clinical class; Venous Clinical Severity Score (VCSS); Aberdeen Varicose Vein Questionnaire (AVVQ); periprocedural pain; and complications. RESULTS: 100% of the cases have been technically successful. At the 6-month follow-up, all treated SSVs were occluded. The 12-month assessment duplex doppler showed anatomical success in patients with 95.8% (95% confidence interval, 0.756-0.994). The CEAP clinical class, VCSS, and the AVVQ had decreased significantly at the 6- and 12-month follow-up, respectively. CONCLUSIONS: EMWA and concomitant foam sclerotherapy is a feasible and effective technique for treating SSV insufficiency.
