Core Tip

Core Tip: We describe a 67-year-old man was recurrently admitted due to gastrointestinal (GI) active bleeding and hypovolemic shock. According to clinical symptoms, abdominal computed tomography (CT) angiography, and 99mTc-red blood cell single-photon emission CT/CT scan, duodenal bleeding may be caused by the small aneurysm, and primary aortoduodenal fistula was highly suspected. Then he underwent duodenum excision and duodenum-jejunum anastomosis. The symptoms of GI bleeding improved postoperatively.
