As reported, the patient underwent placement of a trapease vena cava filter.The patient is reported to have had a history of situs inversus with dextrocardia and recurrent bilateral deep vein thrombosis (dvt).The indication for the filter placement was reported to be as prophylaxis against pulmonary embolism (pe).The filter was implanted via the left femoral vein and placed at the junction of the l3-l4 vertebrae.The patient is reported to have tolerated the procedure well and without complications.Approximately eleven years after the filter implantation, the patient became aware that the filter had perforated the inferior vena cava (ivc) and was abutting an organ.The patient further reported having experienced anxiety associated with the filter.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 pe via percutaneous placement in the 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 ivc perforation could not be confirmed and the exact cause could not be determined.A review of the instructions for use (ifu) notes vessel damage such as intimal tears and perforation as procedural complications related to ivc filters.Studies have noted a greater than 80% perforation rate overall, with all filters imaged after 71 days from implantation revealing some level of perforation.Clinical factors that may have influenced the event include the patient¿s pre-existing co-morbidities, pharmacological issues and lesion characteristics.The anxiety experienced by the patient does not represent a device malfunction.Anxiety, part of the body¿s natural response to stress and can cause feelings of, but not limited to, nervousness, mental anguish, fear, unease and worry.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.

As reported in the legal brief, a 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 perforation and perforation abutting an organ.Per the implant records, the patient was reported to have situs inversus with dextrocardia and recurrent bilateral deep vein thrombosis (dvt).The filter was indicated to prevent pulmonary embolus.Using standard sterile preparation, the left femoral vein was accessed and an inferior vena cavogram was performed.The inferior vena cava (ivc) filter was deployed at the junction of the third and fourth lumbar vertebrae using fluoroscopy guidance.The patient tolerated the procedure well.According to the information received in the patient profile form (ppf), the patient reports perforation of filter struts outside the ivc, perforation abutting an adjacent organ and further experienced anxiety related to the filter, becoming aware of these events approximately eleven years after the filter implantation.
