Secondary Ablation of Recanalized Saphenous Vein after Endovenous Thermal Ablation.

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.

Endovascular radiofrequency ablation. Effect on the vein diameter using the ClosureFast(®) catheter.

Introduction: Endovascular radiofrequency with first generation catheters was not successful due to its technical difficulty and restrictions in veins with diameters larger than 12mm. 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.
