[Secondary aorto-duodenal fistula and aneurysm of the abdominal aorta].

A case report of a man 58 years old with a history of surgical treatment for an aortic-abdominal aneurysm by an aortobifemoral bifurcated vascular graft is presented. The patient was admitted on Urgencies with digestive hemorrhage and he was submitted to an emergent surgical procedure. Surgical findings were a secondary aortoduodenal fistula and an aortic abdominal aneurysm located between renal arteries and the bifurcated prosthesis. Duodenal fistula was then closed and aortic aneurysm removed, interposing an straight Dacron prosthesis. Fifteen days after procedure, patient was discharged and a suitable duodenal and aortic restauration was demonstrated by duodenal transit and angiography. Two months latter, patient is asymptomatic. Relevant details in regard to diagnosis and treatment of such relatively rare affection are commented.
