The authors present a case of a patient with a history of open repair of abdominal aortic aneurysm with a tube graft three years previously presenting with gastrointestinal bleeding as a sign of aortoduodenal fistula. The diagnosis of the fistula was established on the basis of computed tomography angiography, with no source of bleeding found in endoscopy. Endovascular treatment was undertaken due to high operative risk (ASA class IV). A tube stentgraft was implanted covering both anastomoses of the previously implanted prosthesis. In 2-year observation no recurrent gastrointestinal bleeding was noticed.
