CTICasesIatrogenic Aortic Placement of an IVC Filter
Imaging findings
Chest radiograph and CT angiography show an inferior vena cava (IVC) filter placed abnormally within the descending abdominal aorta rather than the IVC, following a bedside emergency placement procedure.
Key takeaways
Accidental aortic placement of an IVC filter is a rare, severe iatrogenic complication. It can occur during bedside insertion without fluoroscopic guidance, especially in volume-depleted patients where vascular anatomy is poorly defined, and necessitates urgent endovascular retrieval to prevent arterial thrombosis.
