Figure 3 Angiographic study. A: The inferior pancreaticoduodenal artery was responsible for the main back flow to the celiac artery; B: The dorsal pancreatic artery (DPA) was responsible for the blood flow of the right hepatic artery; C: Blood re-flow post embolization and the DPA was responsible for the main flow to the celiac artery. IPDA: Inferior pancreaticoduodenal artery; DPA: Dorsal pancreatic artery; SPA: Splenic arteries; RHA: Right hepatic artery; MHA: Middle hepatic artery; CHA: Common hepatic artery; GDA: Gastroduodenal artery; SMA: Superior mesenteric artery; LHA: Left hepatic artery; LGA: Left gastric artery; CeA: Celiac artery.
