A unique case of endovascular reconstruction of occluded duplicate inferior vena cava and review of literature

Inferior vena cava (IVC) filters are indicated in patients with deep venous thrombos is and a contraindication to anticoagulation and are typically removed when they are no longer needed. Real-world data demonstrate that only a small proportion of IVC filters are retrieved, imposing a risk for IVC thrombosis, occlusion, and post-thrombotic syndrome. Here, we present a case of bilateral IVC filter-associated thrombosis in a patient with duplicated IVC and retained filters, treated with endovascular reconstruction. We also perform a selective review of the literature and highlight the efficiency of endovascular stenting across chronically occluded IVC filters in select patients.
