As reported by the legal brief, the patient underwent placement of an optease retrievable vena cava filter.The following additional information received per the patient profile from (ppf) indicates that the device is unable to be retrieved although there have been no known attempts to retrieve the filter on record.The patient also reports to be suffering from swelling in the leg causing pain and mental anguish.According to the medical records, the diagnosis indication for the procedure was thrombolysis.The patient was high risk for deep vein thrombosis (dvt), pulmonary embolism (pe), hypertension and diabetes.

After further review of additional information received the sections have been updated accordingly.It was reported that a patient underwent placement of an optease retrievable vena cava filter.The indication for the implant was a a diagnosis indication for thrombolysis, at risk for pulmonary embolism (pe) and deep vein thrombosis (dvt).The patient¿s medical history is also significant for hypertension and insulin dependent diabetes.The device was deployed via the right femoral vein with no reported complications.Additional information contained in the patient profile form indicated that the device was unable to be retrieved although there have been no known attempts to retrieve the filter on record.The patient also reports to be experiencing persistent swelling in the leg causing pain and mental anguish.There is currently no additional information available.The product was not returned for analysis as it remains implanted.A review of the device history record revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported event.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 pulmonary embolism where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pulmonary embolism 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.The optease vena cava filter is indicated in the us for retrieval up to 14 days post implantation.Following this period of time, and as early as 12 days, there is potential for endothelialization (growth of endothelial cells within the inner wall of the vessel) around the filter struts.Usage of the product other than that indicated in the product's ifu may involve additional risks not described in the labeling.The predominant concern is the development of endothelialization, which would make subsequent removal difficult.Endothelialization has been shown to lead to explantation problems after as short a period as 12 days.Without images or procedural films for review the reported embedded/retrieval difficulty could not be confirmed.Clinical factors that may influenced any potential events include underlying patient co-morbidities, pharmacological and lesion characteristics.Blood clots that develop in the veins of the leg or pelvis, may be related to a condition called deep vein thrombosis (dvt).Large thrombus within the vena cava or lower extremities may impede perfusion and cause venous insufficiency.With time, high pressure in the leg veins due to venous insufficiency of either the superficial or deep veins (or both) can cause leakage of blood out of the capillary beds, resulting in swelling of the affected extremity, resulting in discomfort associated with the edema.Anxiety does not represent a device malfunction and may be related to underlying patient specific issues.With the limited information currently available for review it is not possible to determine what factors may have contributed to the reported events, there is also 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.
