Patient allegedly received an implant on (b)(6) 2011 via the right femoral vein due to morbid obesity.Patient is alleging device tilt and vena cava perforation.Patient notes and further alleges experiencing "from time to time, i get very bad headaches and my right leg hurts", per the (b)(6) 2018 ct abdomen: "the inferior vena cava is difficult to evaluate due to the lack of contrast and lack of intra-abdominal fat.However, the ivc filter is tilted medially.The apex appears to perforated through the medial wall of the ivc.The tip is located below the left vein although it is above the level of the right renal vein.The anterior, lateral, medical and posterior struts appear to lie outside the margins of the vein suggesting perforation.The lateral strut appears to perforate by 2.9 mm.The posterior strut also appears to have perforated for a length of a few millimeters but this is difficult to quantify.The anterior and medial struts have just perforated the wall of the ivc without clear fat planes.There is no penetration of the aorta or adjacent organs".Original: it is alleged that "[pt] received a cook gunther tulip filter on (b)(6) 2011.It is alleged that the [pt] was injured without further explanation.Hospital and medical records have been requested but not yet provided.".
