Manufacturing review: a device history record review could not be performed as the lot number is unknown.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Post-deployment, it was noted that an inferior vena cava filter was migrated, which could have been the cause of abdominal pain.Approximately, three years and ten months later, the patient was admitted to the hospital with abdominal pain and the prongs of the inferior vena cava filter was penetrated the inferior vena cava wall and also a small bowel.Filter removal procedure was performed.Under ultrasound guidance, the right internal jugular vein was accessed with an 18-gauge needle.A guidewire was passed.A 5-french was placed, and a hard copy was saved.Under ultrasound guidance, the right common femoral vein was identified and accessed with an 18-gauge needle.A guidewire was passed.A 5-french sheath was introduced.Then, the omni flush catheter was placed in the right femoral vein, right femoral venogram was performed, and then the catheter was placed in the inferior vena cava and inferior venacavogram was performed.The right jugular sheath was exchanged with a 12-french filter removal system.Then a snare was passed and was able to grasp the hook of the snare and the filter was removed by advanced the sheath.The filter was in the sheath and it was taken out completely.After removal of inferior vena cava filter, there was no evidence of extravasation or thrombus.From the previous study, it was reported that an inferior vena cava filter was unchanged which demonstrated that one limb extended behind the abdominal aorta, possibly into a lumbar vein.Therefore, the investigation is confirmed for the perforation of the inferior vena cava (ivc) and filter migration.Based on the available information, the definitive root cause is unknown.Labeling review: a review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, and unit label) showed that the product labeling is adequate.
