Abstract Aortocaval fistula is an unusual complication of an abdominal aortic aneurysm. We describe 2 patients with abdominal aortic aneurysms who presented with acute renal failure and hepatic injury secondary to spontaneous aortocaval fistulas. The fistulas were shown by computed tomography, right heart catheterization, and abdominal aortography, and were confirmed at surgery. Increases in the fractional excretion of filtered sodium, the urine sodium concentration divided by the urine-to-plasma creatinine ratio (the renal failure index), and the urine sodium concentration were observed. The patients recovered renal and hepatic function after closure of the fistulas. Increased venous pressure resulting from aortocaval shunt might cause the alteration of renal and hepatic function. Therefore, it is important to accurately diagnose the aortocaval fistula and to close it urgently by surgical methods.
