A History of Spine Surgery Does Not Influence Outcomes After Iliofemoral Vein Stenting

Spine surgery is a possible risk factor for development of symptomatic peripheral venous outflow obstructions (PVOO). There insufficient research assessing whether spine contraindication iliofemoral vein stenting (IVS). We undertook this study to determine differences in presentation and outcomes after IVS chronic PVOO patients with history vs those without. retrospectively analyzed database 876 at single institution who underwent from 2011 2020. Patients were stratified into groups based on the presence or absence (n = 31 [3.5%], n 845 [96.5%]). Presenting symptoms both cohorts quantified using Venous Clinical Severity Score (VCSS). Multivariate logistic regression models used odds minor major reoperations. had greater preoperative ulcer size (0.3 0.1; P .021) longer duration (0.5 0.2; .004) than without surgery. This group also presented preoperatively lower VCSS score varicose veins (0.9 1.3; .023). less likely have reoperation (odds ratio, 0.26; 95% confidence interval, 0.06-0.82; .038). Postoperatively, an increased pain (1.2 0.9; .021). One-year poststent, continued present (0.4 0.1 [P .009] 0.4 .002]). similar clinical improvements no significant difference change 1, 2, 3 years poststent (P .811, 0.621, 0.641). was likelihood having between did not 2.03; 0.68-5.39; .175). before but rates improvement as their nonsurgical counterparts. higher reoperations undergo poststent. A should be considered IVS.
