Pre-radioembolotherapy arteriography in a 55-year-old man with hepatic metastatic colorectal cancer. (A) Celiac arteriogram. Splenic artery (thin black arrow) and common hepatic artery (thick black arrow) arise normally. Note numerous hepatic metastases (white arrows). (B) Proper hepatic arteriogram. The gastroduodenal artery has been coil embolized (single arrow). Note opacification of the right gastric artery arising from the proper hepatic artery (arrowheads). (C) Left gastric arteriogram. The left gastric artery (arrow) anastomoses with the right gastric artery (arrowheads) along the lesser curvature of the stomach. (D) Retrograde access of the right gastric artery. Digital Photospot image demonstrating a microcatheter and wire at the origin of the right gastric artery in preparation for coil embolization. (E) Postembolization proper hepatic arteriogram. The gastroduodenal (single arrow) and right gastric artery (arrowheads) have been coil embolized and demonstrate absence of flow to the gastroduodenal region.
