Bilateral renal artery thrombosis secondary to acute necrotizing pancreatitis

Renal artery thrombosis is a rare, but serious and often under-diagnosed condition. We report a case of bilateral renal artery thrombosis secondary to acute necrotizing pancreatitis. A 66-year-old female presented with abdominal pain and acute kidney injury (AKI). A renal biopsy showed organized intraluminal thrombi and a computer tomography scan of the abdomen showed bilateral renal artery thrombosis. Emergent laprotomy showed necrosed pancreas. Doppler studies showed deep vein thrombosis of the lower extremities and internal jugular vein thrombosis. Workup for hypercoagulability was unremarkable. The final diagnosis was AKI secondary to bilateral renal artery thrombosis probably due to hypercoagulability of acute necrotizing pancreatitis.
