RESUMO
The purpose is to evaluate the role of endovascular management for primary aortoduodenal fistula in poor surgical risk patients. A 70-year-old-man was admitted at the emergency room of our hospital with recurrent upper-gastrointestinal bleeding. A diagnostic workup was suggestive of a primary aortoduodenal fistula caused by erosion of an infrarenal abdominal aortic aneurysm. Intractable cardiac arrhythmia, recurrent hemorrhage, and poor patient condition were compatible with an exceedingly high surgical risk. The fistula was successfully treated, and gastrointestinal bleeding was eliminated with placement of a Lifepath endoluminal aortoiliac stent graft. At the 21-month follow-up, the patient was not presenting with symptoms and signs of graft infection, and radiologic studies confirmed decreasing aneurysm size without associated signs of local sepsis. Endovascular stent grafts can efficiently arrest massive exsanguination in critically ill patients with primary aortoenteric fistula. The risk of graft infection remains the most serious problem associated with this approach.
