H10: manufacturing review: the device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately, six years and seven months post filter deployment, the inferior vena cava filter was occluded with scar, large collaterals both cutaneous and mesenteric.Venoplasty of right femoral and external iliac veins was performed with good result.The common iliac and inferior vena cava was very hard and a straight glide complete total occlusion wire would not cross.Around, one month and four days later, angiogram was performed which showed that the filter was occluded with very impervious hard scar tissue.It could be crossed with cook cxi cath but with no reasonable iliac vein remains.Around, three years one month later, computed tomography of abdomen without contrast was performed which showed stenosis of the inferior vena at the level of inferior vena cava filter was likely due fibrosis.A contrast-enhanced study would offer more sensitive evaluation for inferior vena cava occlusion.Therefore, the investigation is confirmed for occlusion of the inferior vena cava (ivc).The definitive root cause could not be determined based upon available information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.H10: d4 (expiry date: 04/2010).H11:section a through f - 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.
