Endovascular treatment of two aortoduodenal fistulae

We report the endovascular treatment of two patients presenting with aortoduodenal fistulae. The first patient was a 66-year-old man admitted with hematemesis. He was on clopidogrel and had received a cryopreserved aortic graft for a mycotic abdominal aortic aneurysm five years earlier. Computed tomography (CT) showed aortic pseudoaneurysms in close contact with the duodenum. Endovascular repair was carried out. Twenty-seven months after the procedure the patient remains asymptomatic. The second patient was a 78-year-old man admitted with abdominal pain and nausea. CT revealed an abdominal aortic pseudoaneurysm and aortoduodenal fistula. He suffered from severe chronic obstructive pulmonary disease that greatly increased his surgical morbidity and mortality. An endovascular repair was performed under epidural anesthesia. The patient died of a postoperative pneumonia 38 days after surgery. These two cases illustrate the importance of endovascular aortic repair especially when an open surgical procedure is either difficult or impossible.
