Secondary ablation of recanalized Saphenous vein after endovenous thermal ablation.
2020
Abstract Objective To describe the occlusion rate and clinical response of a redo ablative procedure in symptomatic patients with recanalization of saphenous vein after endovascular thermal ablation (ETA). Methods A retrospective cohort study was performed in a prospectively collected data of symptomatic patients with recanalization of great or small saphenous vein after ETA who underwent a secondary ablation (SA) from June 2015 to May 2018. Results Ten patients (15 limbs) with recanalization of great or small saphenous vein were treated with SA. The median age was 67 years and 60% were men. The median time from the first ablation was 7.3 years (IQR 6.5 - 9.6). For SA, radiofrequency (RFA) was performed in 12 limbs (80%) and Ultrasound-guided foam sclerotherapy (UGFS) in 3 cases (20%). The Great Saphenous Vein was the treated vessel in 14 cases (93.3%). No complications were reported. Median follow-up was 13 months. Preoperative and 1 year follow-up VCSS was 9 (IQR 5-10) and 4 (IQR 2-8), respectively. Doppler Ultrasound evaluation after 1 year showed an occlusion rate of 93.3% evidencing a partially recanalized vein in 1 treated limb. Conclusion In this study, the occlusion rate was 93.3% one year after Secondary ablation (SA); clinical improvement and no complications were reported. SA appears to be a valid option for the treatment of symptomatic patients with recanalized GSV or SSV.
