Placing two inferior vena cava filters for the bail-out management of opening failure of an inferior vena cava filter.

A 93-year-old man with a femoral fracture was admitted to the emergency department. The patient presented with severe hypoxemia and shock. Enhanced computed tomography confirmed deep venous thrombosis in the left leg and pulmonary embolism. Subsequently, an inferior vena cava filter (IVCF) was implanted. Although the IVCF was completely unsheathed for deployment, it remained fully folded and did not open; it was not deployed or retrieved. A new IVCF was successfully placed in the same position. Acute treatment for the deep venous thrombosis and further pulmonary embolism was achieved.
