Comparative effectiveness of non-compounded polidocanol 1% endovenous microfoam (Varithena) ablation versus endovenous thermal ablation utilizing a systematic review and network meta-analysis.

Objective: We compared the effectiveness and safety of polidocanol 1% endovenous microfoam ablation vs endovenous thermal ablation with radiofrequency or laser energy for treatment of venous insufficiency caused by lower extremity truncal vein incompetence via network meta-analysis of published comparative evidence.

Methods: We conducted a systematic literature review following best practices, including a prospective protocol. We screened studies published in English from 2000 to 2023 for randomized and nonrandomized studies reporting direct or indirect comparisons between polidocanol 1% endovenous microfoam and endovenous thermal ablation.

Relationship between iliofemoral venous stenting and femoropopliteal deep venous reflux.

Objective: Severe presentations of chronic venous insufficiency can result from reflux or obstruction at the deep venous, perforator, or superficial venous levels. Iliofemoral venous stenting can be used to address central venous obstruction; however, its effects on deep venous reflux (DVR) have remained unclear. The purpose of the present study was to evaluate the effects of iliac vein stenting on femoropopliteal DVR with the hypothesis that ultrasound evidence of DVR would remain absent or would have improved after iliac vein stenting.

A single-center experience of anterior accessory saphenous vein endothermal ablation demonstrates safety and efficacy.

Objective: Endothermal ablation is well-established for the treatment of the great and small saphenous veins. Data are lacking for treatment of the anterior accessory saphenous vein (AASV). The purpose of this study was to evaluate the safety and efficacy of AASV treatment using endothermal ablation.

A pre-clinical animal study of a novel mechanical-only ablation device treatment for superficial venous disease.

Objective: Current minimally invasive techniques for ablation in superficial venous reflux are limited to thermal based systems requiring tumescent anesthesia, non-thermal chemical sclerosants and permanent glue implantation. The aim of this feasibility study was to determine the safety and efficacy of a novel mechanical-only ablation (MOA) device called EnVena, in a recognised large animal model with chronic follow up.

Methods: Venous ablation of six lateral saphenous veins in three sheep was performed using the EnVena device.
