CTICasesEmbolized Fractured IVC Filter Fragments
Imaging findings
Chest radiograph and chest CT show multiple linear, metallic densities within the lobar and segmental pulmonary arteries, representing fractured and migrated struts of a Greenfield inferior vena cava (IVC) filter.
Key takeaways
Fracture and distal embolization of IVC filter components to the heart and pulmonary vasculature is a known long-term complication, especially with retrievable filters left in place chronically. Migrated struts can cause chest pain, arrhythmias, or vascular perforation, requiring endovascular extraction.
