Retrieval of the recovery filter after arm perforation, fracture, and migration to the right ventricle.

The authors report a case of inferior vena cava filter arm perforation, followed by fracture and migration to the right ventricle causing chest pain and nonsustained ventricular tachycardia. Review of abdominal computed tomographic (CT) scans show the two filter arms that fractured and migrated had perforated the vena cava 2 years previously. Microscopic evaluation of the retrieved filter and limbs revealed bending metal fatigue at the fracture sites. This case and review of the literature suggest a causal relation between Bard Recovery filter arm perforation and subsequent fracture and migration. Percutaneous retrieval of filters with arm fracture or arm migration is recommended.
