Clinical significance of variant hepatic artery in pancreatic resection: A comprehensive review

Figure 6 Collateral pathways due to celiac axis stenosis. A: Computed tomography scan showed a mass in the pancreatic head with dilated biliary-pancreatic duct, and celiac axis stenosis (CAS, arrow); B: Sagittal maximum intensity projection image demonstrated CAS (arrow); C: Selective celiac angiographic examination revealed the left gastric artery and splenic artery, with no hepatic arteries depicted, which is compatible with occlusion of the common hepatic artery; D: Superior mesenteric arteriogram demonstrated retrograde filling of the celiac branches via the pancreaticoduodenal arcades (arrow) by way of the gastroduodenal artery and anomalous blood vessels traversing the pancreas (arrowhead).
