[Aorto-duodenal fistula--a late complication after infrarenal aortic replacement].

Peripheral atherosclerotic vascular disease is associated in up to 12% with an abdominal aortic aneurysm (AAA). If operation is required AAA is treated in 90% by infrarenal dacron graft implantation. As late complication secondary aortoduodenal fistula is diagnosed in 0.1-4.0%. Mortality in untreated patients is 100%, perioperative mortality depending on operative technique is 17-77%. We present 2 case reports and diagnostic, operative and prophylactic methods.
