Abstract:
We present the case of a 80 years-old male patient who underwent a CT angiogram due to hematemesis and hypovolemic shock. An upper gastrointestinal endoscopy revealed a large clot that closed the antrum and abundant red blood in the pyloric-antrum region. Sclerosis was performed blindly and the bleeding origin was not identified and the success of the sclerosis could not be evaluated. A primary aorta-duodenal fistula was observed by CT angiography, which was treated with an endograft and femoro-femoral bypass. The patient was discharged 14 days after admission.
