Abstract

A 53-year-old man developed a deep venous thrombus (DVT) and pulmonary embolism (PE) shortly after an open Roux-en-Y gastric bypass was performed. He later suffered a life-threatening gastrointestinal bleed while on anticoagulation for the DVT. Thus, anticoagulation was held and an inferior vena cava (IVC) filter (G2, Bard Inc., Tempe, AZ, USA) was placed for PE prophylaxis. About 10 days after filter placement, he presented with severe low back pain and syncope. He also presented with hypotension and anuria unresponsive to intravenous fluids. A STAT non-contrast CT scan of the abdomen revealed that his IVC filter had migrated from an infrarenal to a suprarenal position. Given the high clinical suspicion for renal vein thrombosis, an attempt at IVC filter retrieval was made. The filter could not be retrieved because it was embedded in a large IVC thrombus that extended from the hepatic veins down to the common iliac veins. The patient received nearly 4 days of tPA that was administered at the site of the thrombus with a long thrombolytic catheter (UNIFUSE, Angiodynamics, Queensbury, NY, USA). While his creatinine peaked at 7.6 on hospital Day 4, he eventually began to produce urine and his creatinine had declined to his baseline of 1.0 on follow-up 1 month later. About 18 months after admission, his creatinine had further declined to 0.8. We report the first published case of acute renal failure due to bilateral renal vein thrombosis in the setting of IVC filter migration and thrombosis. This report highlights an important, but rare complication of IVC filter placement as well as the non-operative management of acute bilateral renal vein thrombosis.
