A greenfield filter was implanted on (b)(6) 2006.On (b)(6) 2017, it was noted there was a perforation.The filter was noted to be fractured, tilted and migration had occurred.No further patient complications were reported.It was further reported the patient has a medical history of blood clots with pulmonary embolism (1990s; was on warfarin anticoagulation until 2006; has greenfield filter).On (b)(6) 2015 a ct of the abdomen revealed the ivc filter was within the infrarenal ivc and was unchanged in appearance.The patient was admitted on (b)(6) 2015 and a ct of the pelvis showed presumed osteophyte between the anterior vertebral body and area adjacent to the ivc filter.It was unclear how this was related, especially since the filter was placed in 2006 and bony growth was likely to have occurred prior to onset of pain symptoms.Patient was deferred to vascular surgery/radiology on significance of this finding and whether this warranted removal of the filter.An x-ray of the lumbar spine performed on (b)(6) 2016 revealed a fracture of the caudal portion of one of the filters legs which extended into the anterior l2-l3 disc.A ct of the abdomen dated (b)(6) 2017 demonstrates the filter was abnormally tilted with penetration of the legs of the filter into the pericaval/mesenteric fat, a mesenteric vein, and into the anterior periosteum of a lumbar vertebra.A cta of the abdomen and pelvis with contrast was performed on 01mar2019 revealed the ivc filter was fractured with perforated struts.One of the posterior most struts fractures at the level of superior endplate of l3 vertebral body.Removal of the ivc filter at this time was not thought to be beneficial.
