Patient allegedly received an implant on (b)6) 2011 via the right internal jugular vein due to post deep vein thrombosis (dvt).The patient alleges tilt, vena cava perforation, and organ perforation.The patient further alleges abdominal swelling, limited mobility, and fear.On (b)(6) 2011, per a report from implant report; ¿the filter was released at the level of l2 with full deployment of the legs.Initial deployment was slightly tilted to the left, but redeployed with a satisfactory position.¿ on (b)(6) 2019, per a report from computed tomography: "there is a gunther tulip type ivc filter in place in the inferior vena cava.The filter is tilted 9° towards the right side but parallel to the long axis of the ivc.All 4 of the larger metallic struts project outside of the ivc wall by up to 1 cm in length and 5 mm in the transverse plane.The left-sided struts protrudes into the right lateral wall of the abdominal aorta is a region of focal disruption of the aortic mural calcification"."an anterior strut contacts the posterior surface of the transverse duodenum.The upper tip of the filter partially crosses the confluence of the ivc and renal veins.No broken fragments are identified".
