title: Greenfield inferior vena cava filter dislodged during central venous catheter placement.
abstract: Two cases of a Greenfield inferior vena cava (IVC) filter being dislodged during central venous catheter placement are described. This event appears to be related to J-tip guidewire use during venous catheterization. To our knowledge, this occurrence previously has not been reported. One of the two filters was dislodged from the IVC to a new position in the right atrium. Dislodging of the filter in these two particular cases did not give rise to clinical signs or symptoms.
