Manufacturing review: the device history record (dhr) could not be performed as the lot number is unknown.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately six years and eight months post filter deployment, patient presented with abdominal pain, flank pain and an ivc filter was poking through the vein walls.A day later, ct revealed an ivc filter was tilted with many of the limbs of the filter projecting beyond the walls of the ivc.Some of the limbs project into the region of the aorta as well as into the anterior aspect of the l3-l4 disc space.Eventually a month later, patient presented with abdominal pain.Subsequent ct revealed, filter tines are again noted to extend beyond the borders of the ivc, containing the anterior aspect of the vertebral column and the aorta.Therefore, the investigation is confirmed for the perforation of the ivc.However, the investigation is inconclusive for filter tilt and pe post implant.Based upon the available information, the definitive root cause is unknown.Labeling review: 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.
