Retrieval of intravascular foreign bodies with the snare and catheter capture technique.

The authors report two cases of retrieval of iatrogenically placed intravascular metallic foreign bodies: a guide wire in the abdominal aorta and a guide-wire fragment in the inferior vena cava. The foreign bodies were retrieved with use of a new approach described as the "snare and catheter capture technique." This technique is useful with guide wires that are too stiff to safely remove doubled over.
