Manufacturing review: a lot history review was performed.This is the only complaint to date for this lot number.Therefore, a device history record review is not required.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately one year and five months, post filter deployment computed tomography revealed right lower lobe subsegmental intraluminal filling defect suggests pulmonary embolus.Approximately two months later, computed tomography revealed right lower lobe subsegmental pulmonary embolus.Approximately one month later, computed tomography revealed right lower lobe subsegmental pulmonary arterial filling defect consistent.Approximately one year later, computed tomography revealed a small subsegmental intraluminal filling defect was seen in the right lower lobe.Approximately seven years later, computed tomography revealed the filter nose touched the right lateral wall at the level below the renal vessels with approximately 17 degrees of tilt.One leg extends through the left anterior wall extended 1 cm to the level anterior to the aorta.One posterior leg extends along the posterior wall of the aorta approximately 1.6 cm from the inferior vena cava wall.One leg from the mid left lateral wall extends 1 mm into the right lateral aortic wall.Therefore, the investigation is confirmed for perforation of the inferior vena cava (ivc) and filter tilt.Additionally, it can be confirmed that the patient experienced pulmonary embolism post deployment.However, the relationship to the filter is unknown.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.Expiry date: 11/2011 the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
