    Abstract:
    OBJECTIVE: In the present study, we evaluated the feasibility of a self-expanding venous stent for treating iliofemoral venous obstruction. METHODS: The present retrospective study reviewed the data from 49 patients who had undergone Zilver Vena (Cook Medical, Bloomington, Ind) stent placement for treatment of iliofemoral venous obstruction from September 2017 to March 2019. All patients had undergone received follow-up duplex ultrasound examinations to assess for stent patency. The Villalta scores and Venous Clinical Severity Scores (VCSSs) were also calculated to stratify the postoperative improvement in disease. RESULTS: Of the 49 patients, 19 had had acute deep vein thrombosis, 7, nonthrombotic iliac venous lesions, and 23, post-thrombotic syndrome. At 1 year after Zilver Vena stent placement, the primary, assisted primary, and secondary patency rates were 93.8%, 95.9%, and 97.9%, respectively. The baseline median Villalta score before treatment for those with post-thrombotic syndrome was 19 (range, 11-30), and the median VCSS for the patients with post-thrombotic syndrome and nonthrombotic iliac venous lesions was 11 (range, 6-25). At 1 year after stent placement, the median Villalta score for the post-thrombotic syndrome patients was 4.0 (range, 2-18), and the median VCSS for the post-thrombotic syndrome and nonthrombotic iliac venous lesions patients was 3.0 (range, 2-12). CONCLUSIONS: Venous placement of self-expanding stents offers excellent 1-year patency rates and improved the outcomes of patients with iliofemoral venous obstruction caused by acute deep vein thrombosis, nonthrombotic iliac venous lesions, and post-thrombotic syndrome.
