The exact event date is not known.The exact catalog and lot numbers are not known.It was reported that a patient underwent placement of a trapease vena cava filter.The information provided indicated that the filter subsequently perforated and tilted.There is currently no additional information available for review.The product was not returned for analysis and the sterile lot number has not been provided; therefore, no device analysis nor device history record review could be performed.The trapease vena cava filter is indicated for use in the prevention of recurrent pulmonary embolism (pe) via percutaneous placement in the vena cava for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pulmonary embolism where anticoagulant therapy has failed, or is contraindicated.The purpose of a vena cava filter is to catch thrombus from the lower extremities as it travels along normal blood flow patterns up towards the heart.Without images or procedural films for review, the reported filter tilt and perforation could not be confirmed, and the exact causes could not be determined.Ivc filter tilt has been associated with the anatomy of the vessel, specifically asymmetry and tortuosity.Vessel perforation is a known adverse event associated with implanting vena cava filters and is listed as such in the instructions for use (ifu).The ifu also notes vessel damage such as intimal tears and perforation as procedural and long-term complications related to ivc filters.The timing and mechanism of the tilt and perforation has not been reported at this time and a clinical conclusion could not be determined as to the cause of the event.It is unknown if the tilt contributed to the reported perforation.Given the limited information available for review at this time, there is nothing to suggest that the reported events are related to the design and manufacturing process of the device; therefore, no corrective action will be taken.Should additional information become available, the file will be updated accordingly.

Manufacturer Narrative
|
It was reported that a patient underwent placement of a trapease vena cava filter.The information provided indicated that the filter subsequently perforated and tilted.The patient reported becoming aware of filter fracture, perforation of filter strut(s) outside the inferior vena cava (ivc) approximately ten years and six months post implant.The patient also reported anxiety and worry related to the filter.According to the medical records the patient had a history of a gastrointestinal bleed and underwent an esophagogastroduodenoscopy, two days prior to the filter implant.The patient was diagnosed with erosive gastritis and duodenitis.Details of the filter implant procedure were not provided and there is currently no additional information available for review.The product was not returned for analysis.A review of the device history record revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported complaint.The trapease vena cava filter is indicated for use in the prevention of recurrent pulmonary embolism (pe) via percutaneous placement in the vena cava for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pulmonary embolism where anticoagulant therapy has failed, or is contraindicated.The purpose of a vena cava filter is to catch thrombus from the lower extremities as it travels along normal blood flow patterns up towards the heart.Without images or procedural films for review, the reported filter fracture, tilt and perforation could not be confirmed, and the exact causes could not be determined.Ivc filter tilt has been associated with practitioner technique and vessel anatomy, specifically asymmetry and tortuosity.Vessel perforation is a known adverse event associated with implanting vena cava filters and is listed as such in the instructions for use (ifu).The ifu also notes vessel damage such as intimal tears and perforation as procedural and long-term complications related to ivc filters.The ifu states filter fracture with perforation is a potential complication of vena cava filters.Anatomic locations that create concentrated stress points from filter deformation (for example, deployment at apex of scoliosis, overlapping of either of the renal ostia, or placement adjacent to a vertebral osteophyte) may contribute to fracture of a particular filter strut.Anxiety does not represent a device malfunction and may be related to underlying patient specific issues.Given the limited information available for review at this time, there is nothing to suggest that the reported events are related to the design and manufacturing process of the device; therefore, no corrective action will be taken.Should additional information become available, the file will be updated accordingly.Corrected data section d6: the implantation date was modified.According to the medical records the filter was implanted on (b)(6) 2008.

Event Description
|
Additional information received per the medical records indicate that the patient has a history of erosive gastritis, duodenitis and gastrointestinal bleeding.Two days prior to the implantation of the filter the patient had an esophagogastroduodenoscopy.There was a moderate degree of duodenitis and a moderate degree of gastritis with superficial erosion.There was no blood seen at the time of the procedure. additional information received per the patient profile form (ppf) states that the patient experienced filter fracture within the inferior vena cava (ivc) and perforation of filter strut(s) outside the inferior vena cava (ivc).The patient became aware of the reported events approximately ten years and six months after the index procedure.The patient continues to experience anxiety and worry.
