چکیده
Spontaneous aortocaval fistula is a rare complication of abdominal aortic aneurysms. We describe two cases ofspontaneous aortocaval fistula. The first patient is a woman who was admitted with abdominal pain and pulsatileabdominal mass. Another patient was a man admitted with progressive abdominal pain and hypotension. Computedtomography (CT) scan in both patients showed an infrarenal aortic aneurysm and simultaneous contrastenhancement in the inferior vena cava. Both patients underwent an urgent laparotomy in which the diagnosis ofan aortocaval fistula was confirmed. We review the literature on spontaneous aortocaval fistula as a consequenceof complicated aortic aneurysms.
