Percutaneous retrieval of a radiolucent foreign body from an EVAR device by combining different image modalities.
Percutaneous extraction techniques are an established method for removing endovascular foreign bodies. Generally, the foreign body to be removed is radiopaque (i.e., catheter and guidewire fragments, vena cava filters, embolization coils, endovascular stents). We propose an application of these techniques to remove a radiolucent foreign body (i.e., pigtail cover) by means of a combination of different imaging techniques (fluoroscopy, digital subtraction angiography, ultrasound, and computed axial tomography).
