Endovascular treatment of nonvariceal acute arterial upper gastrointestinal bleeding

Figure 2 Fifty-four years old male with hereditary polyposis and colectomy some years earlier. A-D: Because of polyps in the second part of the duodenum, Whipple’s operation was performed. Two weeks later severe upper gastrointestinal bleeding was seen. Abdominal computed tomography shows a large intraperitoneal haematoma and active bleeding and/or (pseudo)aneurysm; E: Superior mesenteric arteriography showing pseudoaneurysm and bleeding from, most probably, a transverse pancreatic artery branch. Vascular spasms are seen after placement of a microcatheter in the vessel; F: After embolization with microcoils in two branches supplying the pseudoaneurysm/bleeding.
