Reporter occupation: other, senior counsel, litigation.Please note that the exact event date is unknown and the event date is the complaint awareness date.It was reported that a patient underwent placement of a trapease vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused inferior vena cava (ivc) wall perforation and stenosis.The indication for the filter implant has not been provided and 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 ivc 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 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.Stenosis is an abnormal narrowing of a vessel; this does not represent a device malfunction and may be related to vessel characteristics and/or patient factors.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 reported events has not been reported at this time and a clinical conclusion could not be determined as to the cause of the event.Without procedural films or post implant imaging available for review, the reported perforation and stenosis could not be confirmed or further clarified.There is nothing to suggest that the reported event is related to the design and/or manufacturing process of the device; therefore, no corrective action will be taken.Should additional information become available, the file will be updated accordingly.Please note that this is the initial report for this product.

Additional information received per the medical records indicate that the patient has a history of chronic iron deficiency anemia, chest pain, left pleural effusion with atelectasis, elevated left hemidiaphragm, diabetes, gastric arteriovenous malformation, diverticulosis, hemorrhoids, adrenal insufficiency, paroxysmal atrial fibrillation, paraplegia secondary to a motor vehicle accident, post-traumatic stress disorder, allergic rhinitis, chronic pain syndrome, autonomic dysreflexia, neurogenic bladder (has a suprapubic catheter), seizures, homocystinemia, protein s deficiency, hiatal hernia, gastric reflux disease, gastric leiomyoma, cva x2, degenerative joint disease, mitral valve prolapse, insomnia, and hypercoagulable state.The indication for the filter placement was left leg deep vein thrombosis (dvt) and inability to anticoagulate due to drop in hematocrit and hemoglobin.The filter was deployed in the infrarenal inferior vena cava (ivc).Filter placement was immediately followed by placement of a peripherally inserted central catheter (picc) line via the right basilic vein.Nine days post implant, a magnetic resonance imaging (mri) of the abdomen was performed to rule out adenoma, no lesions were observed.Twelve days post implant a computed tomography (ct) scan of the abdomen and pelvis was performed due to a history of anemia, swollen leg and dvt.Results of the scan noted no pelvic masses or adenopathy, diffuse swelling of the left lower extremity and surgically absent uterus.The ivc filter is in place.Thirteen years and one month post implant, a ct scan of the abdomen was performed.The original radiology results were not provided.The images were submitted to additional review approximately two years after the scan was performed and noted ivc stenosis and 3mm mesenteric perforation.Additional information received per the patient profile form (ppf) states that the patient became aware of perforation of filter struts outside the inferior vena cava (ivc) and stenosis approximately thirteen years and one month post implant.The patient also reported shortness of breath, chest pain and tightness, migraines, nausea and fatigue related to the filter.
