Secondary aorto enteric fistula is a rare and fatal complication that develops after reconstructive aortic surgery. In patients presenting with gastrointestinal hemorrhage symptoms, a detailed anamnesis is required to diagnose aortoenteric fistula, which is outside the usual diagnoses. In this study, a 78-year-old male patient who presented with the complaints of bloody vomiting and abdominal pain, who had a history of aortic surgery 20 years ago and who had no bleeding focus at the endoscopy performed, was diagnosed with aortoenteric fistula after abdominal tomography and surgery, and pathogenesis and diagnostic procedures are emphasized.}, number={2}, publisher={Bolu Abant Izzet Baysal University}
