Spontaneous aortocaval fistula : a case report and literature review

الملخص EN

Spontaneous aortocaval fistula is a rare complication of abdominal aortic aneurysms.

We describe two cases of spontaneous aortocaval fistula.

The first patient is a woman who was admitted with abdominal pain and pulsatile abdominal mass.

Another patient was a man admitted with progressive abdominal pain and hypotension.

Computed tomography (CT) scan in both patients showed an infrarenal aortic aneurysm and simultaneous contrast enhancement in the inferior vena cava.

Both patients underwent an urgent laparotomy in which the diagnosis of an aortocaval fistula was confirmed.

We review the literature on spontaneous aortocaval fistula as a consequence of complicated aortic aneurysms.
