Aorto-duodenal fistulae in a 75-year-old male patient presenting with melena and haematemesis. He had an aortic repair with a surgical tube graft 10 years ago. CTA (axial and coronal reformations) demonstrates contrast extravasation of the infrarenal aorta directly into the adjacent duodenum (ab). The patient died immediately after the CT scan before stent graft implantation could be performed. In a 63-year-old male patient with severe haematemesis ultrasound detected an aortic aneurysm. He had previous aortic repair (15 years ago) and had also been suffering from intermittent haematemesis for 3 months. CTA (c) and DSA (d) demonstrated an aneurysm of the distal anastomosis in close proximity to the duodenum. A bifurcated stent graft was implanted (e). The aneurysm was completely excluded. A follow-up CT on the next day (after oral contrast) nicely demonstrated the aorto-duodenal fistulae (arrow) (f)
