Great Saphenous Vein Sparing Segmental Radiofrequency Ablation in Varicose Veins Patients

86 patients were randomized into hot-CHIVA (n=43) and control (n=43) groups. Study group patients had undergone radiofrequency ablation (RFA) VNUS Closure - FastTM of one segment of GSV close to saphenofemoral junction. Controls had undergone whole refluxing trunk ablation. Additional phlebectomy was performed in all the patients of both groups. Primary end-point was change in quality of life (QoL) measured with CIVIQ-20 at 12 months. Secondary end-points was recurrence of varicose veins at 12 months. The investigators also measured GSV caliber at the median and distal thigh change in hot-CHIVA group.
