Purpose: To assess the outcomes of endovascular management for superior vena cava (SVC) syndrome secondary to fibrosing mediastinitis (FM). Methods: Between January 2004 and December 2016, 10 consecutive patients with endovascularly managed SVC syndrome secondary to FM were identified in an institutional database. Venograms were performed to assess the severity and location of the lesion and allow measurement for stent selection. Standard stenting and angioplasty techniques were utilized to establish luminal patency. The safety, feasibility, clinical success, and the primary and secondary patency were evaluated. Kaplan-Meier survival analysis was used to determine median duration of stent patency. A log-rank test was used to test differences in prior stent use. Results: Our cohort was predominantly female (7/10) with an average age of 42.2 years. Of the 10 patients, 3 had undergone endovascular stenting at an outside institution prior to referral to our institution due to new, recurrent, or worsening symptoms. All patients underwent venography demonstrating stenosis (8/10) or occlusion (2/10) at initial presentation. Stenting or angioplasty was technically successful in 9 (90.0%) patients. Eight of 10 patients had primary stenting, while 1 achieved vascular patency and symptom resolution with angioplasty alone. Median duration of primary patency was 31.3 months (95% confidence interval: 5.9-103). Six (54.5%) patients required secondary revision procedures. Median duration of secondary patency was 6.1 months, with 25% of revisions occurring by 4 months and 75% occurring by 20.9 months. All treated patients (9/9) reported symptomatic relief at 1-month follow-up, establishing a clinical success rate of 100%. There were no 30-day adverse effects related to the procedure. Conclusion: This study demonstrates that endovascular therapy is a safe and feasible approach for managing FM-related SVC syndrome.
