As reported, the patient underwent placement of a trapease vena cava filter.The patient is reported to have had a history of deep vein thrombosis (dvt) of the right lower extremity, severe pancreatitis, renal failure and anemia.The indication for the filter placement was not reported.The filter was implanted at the level of l2.The patient is reported to have tolerated the procedure well.Approximately seven and a half years after the implantation, the patient became aware that the filter had migration and was associated with a possible device site erosion.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 inferior vena cava (ivc) for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pe where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pe 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 migration and device site erosion events could not be confirmed and the exact cause could not be determined.Ivc filter migration is a known potential adverse event associated with all ivc filter implants and is listed in the instruction for use (ifu) as such.Possible causes for filter migration include mega cava, wire entrapment during central venous catheter placement, ¿sail¿ effect (cranial migration) of large clot burden within the filter, mechanical device failure, and operator error.Physiologic causes of migration may result from temporary dysmorphism of the ivc including bending, coughing or valsalva maneuvers resulting in dislodgment of the filter.Some studies suggest that strenuous physical activity and increased intra-abdominal pressure can lead to migration of ivc filters.The report further reported possible vessel erosion at the site of the device.With time, pressure within the vessel can cause irritation and ulceration of the vessel.A review of the ifu notes vessel damage such as intimal tears and perforation as procedural complications related to ivc filters.Clinical factors that may have influenced the event include the patient¿s pre-existing co-morbidities, pharmacological issues and lesion characteristics.Given the limited information available for review, there is nothing to suggest that a malfunction in 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.

Event Description
|
As reported by the legal brief, the patient underwent placement of a trapease vena cava filter.The filter subsequently malfunctioned and caused injury and damage to the patient, including but not limited to dislodged inferior vena cava (ivc) filter with possible erosion.As a direct and proximate result of these malfunctions, the patient suffered life-threatening injuries and damages, and required extensive medical care and treatment.As a further proximate result, the patient has suffered and will continue to suffer significant medical expenses, pain and suffering, and other damages.The following additional information received per the patient profile form (ppf), the patient became aware of the alleged events ninety-one months and twenty-six days post implantation.According to the information received in the medical records, the patient¿s pre-operative diagnosis was deep vein thrombosis (dvt), of the right lower extremity, severe pancreatitis, renal failure and history of anemia.A venacavogram was performed, followed by placement of the filter.The filter was in a good position at the level of l2.The patient tolerated the procedure well, and was returned to the recovery room in stable condition.
