    The endovenous ASVAL method: principles and preliminary results
    (AVES, 2016) Atasoy, Mehmet Mahir; Oguzkurt, Levent
    PURPOSE We aimed to investigate the feasibility and safety of the endovenous ambulatory selective varicose vein ablation under local anesthesia (eASVAL) method in a selected group of patients with varicose disease and present the short-term results of one-year ultrasonographic follow-up. METHODS Three hundred and ninety-five consecutive patients with varicose veins who had been treated with endovenous laser ablation (EVLA) were retrospectively reviewed over a period of two years. From this group, 41 patients who were treated using the eASVAL technique and had the great saphenous vein (GSV) preserved were included in the study. These patients had only limited segmental GSV reflux accompanied by a competent terminal valve. The eASVAL technique can be defined as EVLA of the proximal straight segments of the major tributaries connecting the symptomatic varicose veins with the GSV, followed by ultrasound-guided foam sclerotherapy of the superficial varicose veins themselves. The patients were assessed before and after the treatment by duplex scan findings and clinical assessment scores. RESULTS The GSVs were successfully preserved in all 41 cases, and all patients showed significant clinical improvement using the eASVAL approach (P < 0.001). Segmental reflux was no longer present in 75.3% of patients. The mean diameters of the GSVs were significantly reduced at one-year follow-up (8.5 mm vs. 7.5 mm, P < 0.001). CONCLUSION eASVAL is a feasible and safe procedure in selected patients, with promising results at one-year ultrasonographic follow-up. However, prospective studies are required, comparing this approach with the standard techniques.

    Targeted endovenous treatment of Giacomini vein insufficiency-associated varicose disease: considering the reflux patterns
    (AVES, 2014) Atasoy, Mehmet Mahir; Gumus, Burcak; Caymaz, Ismail; Oguzkurt, Levent
    PURPOSE We aimed to assess the technical feasibility of targeted endovenous treatment of Giacomini vein insufficiency (GVI)-associated varicose disease and report our early results. METHODS We retrospectively screened 335 patients with varicose disease who underwent endovenous laser ablation from September 2011 to January 2013, and determined 17 patients who underwent Giacomini vein ablation. Using a targeted endovenous treatment approach considering the reflux pattern, all healthy great saphenous veins (GSV) or vein segments were preserved while all insufficient veins (Giacomini vein, perforator veins, small saphenous vein, anterior accessory GSV, major tributary veins, or incompetent segments of the GSV) were ablated. Treatment success was analysed using Doppler findings and clinical assessment scores before and after treatment. RESULTS Targeted endovenous treatment was technically successful in all cases. Seven GSVs were preserved totally and three GSVs were preserved partially (10/17, 58%), with no major complications. Clinical assessment scores and Doppler findings were improved in all cases. CONCLUSION Targeted endovenous treatment of GVI-associated varicose disease is safe and effective. In majority of GVI cases saphenous vein can be preserved using this approach.
