As reported a patient underwent placement of an optease vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused; the superior end of the filter is at the t11-12 interspace (suprarenal location).The filter is tilted anteriorly and laterally at the superior end and contacts the inferior vena cava (ivc wall).The filter is tilted posteriorly at the inferior end and contacts the ivc wall.All the struts of the filter perforate the ivc up to 5mm.Two anterior struts perforate 5mm and contact the right hepatic lobe.One medial strut perforates 5mm and resides within the soft tissues.Two posterior struts perforate 5mm, one contacts the right adrenal gland, and another resides in the soft tissues.One lateral strut perforates 5mm and contacts the right hepatic lobe.The indication for the filter implant, procedural details and medical history of the patient have not been provided and there is currently no additional information available for review.The product is not available for analysis and the sterile lot number has not been provided; therefore, no device analysis nor device history record review could be performed.The optease 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 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.Ivc filter tilt has been associated with operator 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 timing and mechanism of the events has not been reported at this time and a clinical conclusion could not be determined as to the cause of the events.Without images available for review the reported events could not be confirmed or further clarified.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.

As reported in the legal brief, a patient underwent placement of an optease vena cava filter.The filter subsequently malfunctioned and caused injury and damage to the patient, including, but not limited to the superior end of the filter is at the t11-12 interspace (suprarenal location).The filter is tilted anteriorly and laterally at the superior end and contacts the inferior vena cava (ivc wall).The filter is tilted posteriorly at the inferior end and contacts the ivc wall.All the struts of the filter perforate the ivc up to 5mm.Two (2) anterior struts perforate the ivc wall both 5mm and contact the right hepatic lobe.One (1) medial strut perforates the ivc wall 5mm and resides within the soft tissues.One (1) posterior strut perforates the ivc wall 5mm and contacts the right adrenal gland.One (1) posterior strut perforates the ivc wall 5mm and resides within the soft tissues.One (1) lateral strut perforates the ivc wall 5mm and contacts the right hepatic lobe.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.

Event or Problem Description

Additional information received per the medical records indicate that the patient has a history of bilateral renal vein/inferior vena cava (ivc) thrombosis.The filter was implanted via the patient's right internal jugular.The filter was then positioned and deployed in the suprarenal ivc under fluoroscopic guidance.The patient tolerated the procedure without difficulty.The medical record also states that filling defects were identified extending from both renal veins into the ivc.The level of the renal veins was noted.The inferior vena cava filter was deployed in the infrarenal inferior vena cava.Abdominal and pelvic computed tomography (ct) scan done approximately eleven months after the index procedure was re-evaluated eight years and nine months after the index procedure.The results were included in the initial report.Additional information received per the patient profile form (ppf) states that the patient experienced perforation of filter struts outside the inferior vena cava (ivc), perforation of filter struts into organs and filter tilt.The patient became aware of the reported events approximately eight years and nine months after filter implant.The patient also reported anxiety related to the filter.
