¹Hematemesis and endoscopic findings.

²Two surgical approaches were challenged during 14 d.

³Bleeding from the GDA was detected during laparotomy, even though computed tomography angiography and angiographic findings did not revealed extravasation. The endovascular treatment was done under the laparotomy. CHA: Common hepatic artery; CT: Computed tomography; DPA: Dorsal pancreatic artery; EVT: Endovascular treatment; GDA: Gastroduodenal artery; RGA: Right gastric artery; RHA: Right hepatic artery; PHA: Proper hepatic artery; SA: Splenic artery.
