Primary aorto-duodenal fistula (PADF) is a rare life-threatening condition consisting in a direct communication between the abdominal aorta and the gastrointestinal tract without any previous vascular intervention. PADF results most commonly from an abdominal aortic aneurism (AAA) or aortic bacterial/mycotic infection, with the fistula forming between the native aorta and the third or fourth portion of the duodenum. Symptoms are nonspecifc and the diagnosis is often delayed after AAA rupture with bigh rate of morbidity and mortality. We present a case of 69-year-old-male with a history of untreated abdominal aortic aneurysm who came to the attention of the emergency department for Abdominal aortic aneurysm rupture (RAAA). The patient was successfully treated with staged therapy: endovascular aneurysm repair (EVAR) to control hemorrhage rapidly, followed by pancreas sparing duodenectomy and aortic reconstruction with xeno-pericardial tube grafts.
