Fig. 1 Classic hepatic arterial anatomy in 58-year-old man with
metastatic colon cancer to liver. Volume-rendered 3D image created from axial
contrast-enhanced CT data reveals classic branching arterial anatomy. Celiac
axis (short solid arrow) trifurcates into splenic artery, common
hepatic artery (long solid arrow), and left gastric artery. Common
hepatic artery gives rise to gastroduodenal artery (open arrowhead)
and proper hepatic artery (solid arrowhead). Right hepatic artery
(long open arrow) and left hepatic artery (short open arrow)
originate from proper hepatic artery.
