AVLS PRO Venous Registry Study of Saphenous Vein Reflux Treatments and Outcomes

Introduction, Objectives, and/or Purpose: INTRODUCTION
The treatment of superficial chronic venous insufficiency in the lower extremities has experienced major changes in the last several decades, having transitioned from open surgical procedures such as vein stripping and phlebectomy to almost exclusively minimally invasive endovenous procedures. Nevertheless, these procedures are not void of complications. As such, this retrospective Registry study aims to research if anatomical and treatment variations improve outcomes, without increasing the risk of postoperative complications. The outcome of these studies will lead the way to the most appropriate approach for treating venous insufficiency and ulcerative complications.

OBJECTIVES
1. Provide statistical comparison of the results based on vein treated (anatomy, degree of venous insufficiency, compression garment use, CEAP and ulcer characteristics – if present-
2. Evaluate proportions of patients undergoing each treatment method (EVLT, RFA, CAC, PEM) and concurrent treatments
3. Provide statistical comparison prior to and following treatment in terms of VCSS, VVSQ and SF6D scores

Methods: METHODS
The AVLS PRO Venous Registry contains data from 2014-present. The database is owned by the American Vein & Lymphatic Society (AVLS of Chicago, IL). The query was directed toward all patients entering participating centers, including most recent data available as of March 2023.
Demographic variables analyzed include Gender, Age, Sex, Race, BMI. Clinical symptoms, presenting and follow-up measures include CEAP class, VCSS score, VVSQ scores, SSFD score, as well as presenting complaint. Duplex values were interrogated in superficial and deep lower extremity veins to distinguish groups of patients with isolated superficial pathology, mixed deep and superficial pathology, and isolated deep vein pathology. The AVLS Registry was thoroughly reviewed for preprocedural demographic and anatomic information, as well as postprocedural data, including ulcer healing, occlusion, and complication rates.

Results: RESULTS
We have recently received the data extracted from the database for this project and are currently in the process of statistical analysis. We are working with a professional statistician for data analysis.
We greatly appreciate your consideration of our project for presentation as we eagerly await the results of the statistical analysis, and fully expect to have it completed at the time of the presentation.

Conclusion(s): CONCLUSIONS
As superficial venous interventions become more ubiquitous in outpatient practices, it has become relevant to evaluate the treatment of vein disease in large populations. We hope to elucidate whether different treatment methods have a statistical impact on outcomes and complications.
