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.

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.

Article Synopsis
  • Chronic venous disease (CVD) patients may have varying symptoms, from severe conditions to mild visible issues like telangiectasias, which can lead to excessive treatment requests due to perceived flaws.
  • A study with 223 patients revealed that 17% met the criteria for Body Dysmorphic Disorder (BDD), suggesting a significant link between telangiectasias and psychological distress.
  • It is important to assess and possibly refer BDD patients to a psychiatrist before starting any treatment for telangiectasias to avoid unnecessary procedures.

The American Venous Forum (AVF) and the Society for Vascular Surgery set forth these guidelines for the management of endothermal heat-induced thrombosis (EHIT). The guidelines serve to compile the body of literature on EHIT and to put forth evidence-based recommendations. The guidelines are divided into the following categories: classification of EHIT, risk factors and prevention, and treatment of EHIT.

Objective: Patients who present acutely with a femoral deep vein thrombosis (DVT) diagnosed by ultrasound are often treated with anticoagulation and instructed to follow-up electively. This study sought to assess whether obtaining axial imaging of the central venous system results in the identification of additional iliocaval pathology warranting treatment.

Methods: This study was a retrospective review of a prospectively maintained registry from November 2014 through April 2017 with follow-up through March 2020.

The coronavirus disease 2019 (COVID-19) global pandemic has resulted in diversion of healthcare resources to the management of patients infected with SARS-CoV-2 virus. Elective interventions and surgical procedures in most countries have been postponed and operating room resources have been diverted to manage the pandemic. The Venous and Lymphatic Triage and Acuity Scale was developed to provide an international standard to rationalise and harmonise the management of patients with venous and lymphatic disorders or vascular anomalies.

Objective: Many insurance payers are hesitating to cover interventional treatments in patients with isolated symptomatic varicose veins. In this study, we sought to determine the outcomes of patients with varicose veins who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry.

Methods: Using data from the Varicose Vein Registry between January 2015 and March 2019, we investigated immediate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy.

Background: The Vascular Quality Initiative (VQI) Varicose Vein Registry (VVR) represents a patient-centered database launched in January 2015. Previous work describing overall trends and outcomes of varicose vein procedures across the United States demonstrates a benefit from these procedures. The existing gaps in evidence to support current and future Medicare coverage of varicose vein procedures necessitate further description of clinical outcomes in patients ≥65 years old compared with the population <65 years old.
