Manufacturing review: as the lot number for the device was not provided, a manufacturing review could not be performed.Investigation summary: the device was not returned for evaluation.Images were not provided for review.Medical records were provided and reviewed.Approximately four months post deployment, during filter retrieval, it was noted that the head of the filter touched the right posterolateral wall of the vena cava.Multiple retrieval devices and multiple unsuccessful attempts were made to try and position the retrieval device over the head of the filter.The filter was angulated to the right and was attached to the endothelium of the vena cava.Approximately five years three months post filter deployment, a ct demonstrated an ivc filter with multiple malpositioned limbs in addition to a fractured limb.Approximately five years four months post deployment, the filter was removed with nine limbs still attached, a limb from the liver, and two detached limbs from the vena cava.Therefore, the investigation can be confirmed for filter tilt, limb detachment and retrieval difficulties.However, the investigation is inconclusive for perforation of the ivc.Per the provided medical records, the patient underwent exploratory laparotomy surgery following filter deployment.Per the ifu((instructions for use), "procedures or activities that lead to changes in intra-abdominal pressure could affect the integrity or stability of the filter." multiple retrieval devices and multiple unsuccessful attempts were made to retrieve the filter.The filter was angulated and attached to the endothelium of the vena cava.Therefore, the procedure could have affected the integrity and stability of the filter resulting in filter tilt which led to the retrieval difficulties.However, the definitive root cause is unknown.Labeling review: the current ifu (instructions for use) states: precautions: procedures or activities that lead to changes in intra-abdominal pressure could affect the integrity or stability of the filter.Warnings: filter fractures are a known complication of vena cava filters.There have been some reports of serious pulmonary and cardiac complications with vena cava filters requiring the retrieval of the fragment utilizing endovascular and/or surgical techniques.Movement, migration or tilt of the filter are known complications of vena cava filters.A review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, and unit label) showed that the product labeling is adequate.(expiry date: 07/2014); (manufacturing date: 07/2011).(b)(4).

Event Description
|
It was reported through the litigation process that a vena cava filter was placed in a patient in conjunction with trauma situation/motor vehicle accident.At some time post filter deployment, it was alleged that filter limbs perforated into organs and detached.Allegedly the filter tilted sideways and the device was unable to be retrieved.The device and filter limb(s) were removed open abdominal procedure after a previously attempted but unsuccessful percutaneous removal procedure.The patient experienced chronic abdominal pain.However, the current status of the patient is unknown.
