BACKGROUND: 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. METHODS: A retrospective cohort study was performed in a prospectively collected data of symptomatic patients with recanalization of the great saphenous vein (GSV) or small saphenous vein (SSV) after endovascular thermal ablation who underwent a secondary ablation (SA) from June 2015 to May 2018. RESULTS: Ten patients (15 limbs) with recanalization of the GSV or SSV 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 (interquartile range [IQR] 6.5-9.6). For SA, radiofrequency ablation was performed in 12 limbs (80%) and ultrasound-guided foam sclerotherapy in 3 cases (20%). The GSV 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 Venous Clinical Severity Score was 9 (IQR 5-10) and 4 (IQR 2-8), respectively. Duplex ultrasound evaluation after 1 year showed an occlusion rate of 93.3% evidencing a partially recanalized vein in 1 treated limb. CONCLUSIONS: In this study, the occlusion rate was 93.3% at 1 year after 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.

INTRODUCCIÓN: La radiofrecuencia endovascular con los catéteres de primera generación no obtuvo buenos resultados debido a su difícil manipulación y a las restricciones en venas con diámetros mayores de 12 mm. Sin embargo, utilizando los nuevos catéteres no existe evidencia científica suficiente para afirmar que el diámetro represente una limitación técnica. El objetivo del presente estudio fue evaluar y comparar el diámetro pre y postoperatorio de grandes troncos venosos de miembros inferiores para determinar la reducción del calibre que se produce a los 6 meses de la ablación con catéteres de última generación. MÉTODOS: Estudio retrospectivo observacional y descriptivo sobre una cohorte de pacientes con insuficiencia de la vena safena magna, vena safena parva y vena accesoria anterior de la safena magna, operados con catéteres de última generación de radiofrecuencia. Los diámetros fueron evaluados en el pre y en el postoperatorio mediante ecografía. RESULTADOS: Entre el año 2007 y el 2014 se realizaron un total de 365 ablaciones en vasos con un diámetro medio de 9 ± 3,1 mm, observándose una reducción de este a los 6 meses con un valor medio de 5,2 ± 0,8 mm (p < 0,0001). Se observó además oclusión total en el 100% de los casos y complicaciones como trombosis venosa profunda en el 0,5% y trombosis inducida por calor en el 1,1%. CONCLUSIONES: Se comprobó una significativa disminución del diámetro venoso tras el tratamiento endovascular con los nuevos catéteres ClosureFast® incluso en vasos con dilataciones superiores a 12 mm
INTRODUCTION: Endovascular radiofrequency with first generation catheters was not successful due to its technical difficulty and restrictions in veins with diameters larger than 12 mm. However, using the new catheter there is not enough scientific evidence to affirm that the diameter represents a technical limitation. The aim of this study was to evaluate and compare pre and post-operative venous trunks diameter, aiming at the reduction of size after 6 months with last generation catheters. METHODS: Retrospective observational and descriptive study on a cohort of patients with insufficiency of the great saphenous vein, small saphenous vein and anterior accessory vein operated on with last generation radiofrequency catheters. The diameters were evaluated in the pre and post-operative period with ultrasound. RESULTS: Between 2007 and 2014 a total of 365 ablations were performed in veins with an average diameter of 9 ± 3.1 mm showing a reduction of it after 6 months with a mean value of 5.2 ± 0.8 mm (P < .0001). Total occlusion was also observed in 100% of cases and complications such as deep vein thrombosis in 0.5% and heat-induced thrombosis in 1.1%. CONCLUSIONS: A significant reduction in venous diameter after endovascular treatment with the new ClosureFast®catheters was checked, even in veins with diameters greater than 12 mm
