{"title":"The impact of stent protrusion into the inferior vena cava or jailing of the contralateral iliac vein on the incidence of contralateral deep vein thrombosis following venous stenting.","authors":"Duy Nguyen, Karl Pappas, Shreya Mahadevan, Levan Sulakvelidze, Richard Kennedy, Gaurav Lakhanpal, Sanjiv Lakhanpal, Peter J Pappas","doi":"10.1177/02683555241273752","DOIUrl":"10.1177/02683555241273752","url":null,"abstract":"<p><strong>Objective: </strong>Iliac vein stenting is the standard of care for patients with pelvic venous disorders secondary to symptomatic iliac vein outflow obstruction. Venous stents are often extended proximally into the inferior vena cava (IVC) which may result in partial or complete coverage of the contralateral iliac vein. The purpose of this investigation is to determine if extension of iliac vein stents into the IVC results in increased risk of contralateral deep venous thrombosis (DVT).</p><p><strong>Methods: </strong>We retrospectively reviewed prospectively collected data from 409 patients who underwent iliac vein stenting at the Center for Vascular Medicine (CVM) from 2019 to 2020. Stent type, covered territories, initial and follow-up consults, ultrasound and operative reports were reviewed to assess for incidence of post-implantation DVT. Patients were stratified into three groups: Iliac vein stents which protruded into the IVC, stents that completely covered the orifice of the contralateral iliac vein and those with no stent protrusion into the IVC.</p><p><strong>Results: </strong>Out of 409 patients, the average age was 53.96 ± 13.40 years with 94 males and 315 females. All stents placed were Venovo stents and all iliac vein lesions were non-thrombotic stenoses. The average follow-up period was 14.35 ± 10.09 months. The most common territories stented were the IVC-LCIV-LEIV (<i>n</i> = , 74%) and the IVC-RCIV-REIV (<i>n</i> = , 26%). Stent protrusion and distance into the IVC in millimeters (mm) was the following: Partial protrusion (<i>n</i> = 314, 77%, 27.6 ± 19.1), jailing of the contralateral iliac vein (<i>n</i> = 78, 19%, 45.9 ± 18.6), no protrusion (<i>n</i> = 16, 4%). The overall DVT rate post-implantation was 0.49% (<i>n</i> = 2). No DVTs ipsilateral to the index stent were identified and both DVTs were contralateral DVTs. A hypercoaguable disorder was reported in 6 patients (1.5%). There were no significant differences in prevalence of contralateral DVT between the three groups. (<i>p</i> = .35).</p><p><strong>Conclusion: </strong>The rate of contralateral DVTs post iliac vein stenting with Nitonol based stents is extremely low. Partial or complete coverage of the contralateral iliac vein via stenting does not result in an increased incidence of contralateral DVT in the short-term. Longer follow up is needed to determine if contralateral DVTs occur after long-term implantation.</p>","PeriodicalId":94350,"journal":{"name":"Phlebology","volume":" ","pages":"80-87"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141977616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
