Event Description
|
As reported by the legal brief, the patient underwent placement of an optease vena cava filter.The report states that the filter subsequently malfunctioned and caused injury and damage to the patient including, but not limited to filter tilt.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.

Initial 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 an optease vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused filter tilt.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 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 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.Without images available for review the reported event 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.Please note that this is the initial report for this product.

Event Description
|
Additional information received per the medical records indicate that the patient has a history of a clot within the inferior vena cava (ivc), severe obstructive disease in the ivc secondary to paraaortic lymph node compression.A right subclavian vein approach was used to insert the filter below the renal veins.A venography revealed a massive clot formation in the ivc that extended into both iliac veins.The patient underwent mechanical thrombectomy multiple times using an angiojet device; however, they were unable to reestablish flow into the patient's iliac veins.The patient was to restart heparin treatment.Additional information received per the patient profile form (ppf) states that the patient experienced filter tilt.The patient became aware of the reported event approximately nine years and eight months after the index procedure.The patient also experienced a fractured filter which was retained in the vena cava/chest/abdomen.

Manufacturer Narrative

It was reported that a patient underwent placement of an optease vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused filter tilt.The patient reported becoming aware of the event approximately nine years and eight months post implant.The patient also reported a fractured filter which was retained in the vena cava/chest/abdomen.According to the medical record the patient had a history of a clot within the inferior vena cava (ivc), severe obstructive disease in the ivc secondary to paraaortic lymph node compression.The filter was implanted via the right subclavian vein and deployed below the level of the renal veins.A venography revealed a massive clot formation in the ivc that extended into both iliac veins.The patient underwent mechanical thrombectomy multiple times using an angiojet device; however, they were unable to reestablish flow into the patient's iliac veins.The patient was to restart heparin treatment.The product remains implanted and unavailable 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 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.The instructions for use (ifu) states that filter fracture 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.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.
