The patient received an implant on (b)(6) 2010 prior to bariatric surgery followed by a successful, complex retrieval (b)(6) 2018.The patient alleges tilt, vena cava perforation, occluded filter, and deep vein thrombosis (dvt) bilateral common ivc requiring thrombectomy.The patient further alleges fear, anxiety, lifetime blood thinners, and depression.(b)(6) 2018 magnetic resonance imaging (mri) abdomen: "impression: mri confirms what appears to be extensive acute thrombus in the ivc below the ivc filter, extending through the length of the left common iliac and into a large left lumbar vein.3.No thrombus extends above the ivc filter.The ivc above the filter appears normal".(b)(6) 2018, per a report from venogram; ¿findings: persistent 50% thrombus in distal ivc, 20% in proximal left common iliac vein.No thrombus in ivc filter.¿ "final impression: suspect aneurysmal dilatation of the inferior vena cava and the left common iliac vein.Acutely thrombosed bilateral common iliac veins and inferior vena cava were successfully opened with pharmacal-mechanical thrombectomy using the angiojet device.Ivus identification of residual thrombus within the dilated left common iliac and ivc".(b)(6) 2018, per a report from (partial) retrieval report (successful); ¿final impression: safe retrieval of a celect ivc filter.No evidence of thrombus or inferior vena cava injury after filter retrieval.¿.
