Trombosis bilateral de venas renales e insuficiencia renal aguda secundaria a trombosis de un filtro en vena cava inferior.

Resumen

Bilateral renal vein thrombosis is an unusual etiology of acute renal failure and usually is associated with nephrotic syndrome. We report a 77-years old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.
