Procedural and Clinical Outcomes of Dedicated Venous Stents in Acute and Chronic Venous Obstruction: A Retrospective Single Center Study

Abstract

Background Endovenous angioplasty with stenting is an accepted treatment for patient with venous obstruction. Dedicated venous stents have been developed to improve the efficacy and safety of the venoplasty procedure. We report the procedural as well as clinical outcomes of these new generation stents in the treatment of acute and chronic venous obstruction. Method This is a single centre retrospective cohort study of patients who received venous stenting for either acute or chronic venous obstruction. Baseline demographics, procedural details, clinical outcomes including 30 day all-cause mortality, 90 day primary patency rate, and change in Villalta score were reported. Result 41 patients with venous obstruction were included in this study. The mean Villalta score before the procedure was 13.8 (±3.8). Extrinsic compression of the affected vein was found in 95.1% of cases. Procedural success was achieved in 97.6% of cases, with 2±1 stents of mean diameter of 15.3mm +/- 1.9mm and total stented length of 179.3mm±85.3mm used per case. There were no procedural complications. 90 days primary patency rate was 90.2%. The Villalta score decreased by 9.2±0.7 to 4.6±2.4 at 90 days. Conclusion Endovenous angioplasty with new generation of dedicated venous stents is a safe and effective treatment option for patients with acute and chronic venous obstruction.
