The diagnostic approach for exploring the responsible artery for hemorrhage. a: Angiography of the common tract of the superior mesenteric artery (SMA) and splenic artery does not depict extravasation of contrast medium. b: Selective arteriography of the first jejunum artery depicts the suspicious extravasation (*) of contrast medium which was difficult to differentiate from the duodenal wall. c: Superior mesenteric arteriography immediately after embolization depicts the patent first jejunum artery trunk (arrow) with partial occlusion and the movement of the duodenum containing air prevented to interpret the existence of extravasation of contrast medium. d: CT following transcatheter arterial embolization with n-butyl cyanoacrylate lipiodol (NBCA-Lp) of the first jejunal branch artery reveals accumulation of NBCA-Lp at the ventral wall of the ascending duodenum and the jejunum (arrows). e (1): A volume-rendered (VR) image obtained during superior mesenteric arteriography (SMA) (anterior–posterior view). e (2): Diagram of e (1) shows the extravasation and relevant arteries of the first jejunal branch artery (1JA, green) and inferior pancreatic duodenal artery (IPDA, blue). f (1): A VR image obtained during SMA (caudal–cranial view). f (2): Diagram of f (1) shows supply of the ventral and dorsal walls of the duodenum by 1JA and IPDA, respectively.
