Embolization of extrahepatic arteries and Hepatic artery redistribution embolization. a. Selective right gastric arteriogram from left hepatic artery shows right gastric artery (white arrows), embolized with microcoils; b. Left hepatic arteriogram showed accessory left gastric artery (black arrows) arising from left hepatic artery; c. Accessory left gastric artery (black arrows) was selectively catheterized and embolized with coils; d. Proper hepatic arteriogram shows whole hepatic artery without extrahepatic supplies. Black arrowheads refer to coils embolized in the accessory left gastric artery and right gastric artery. e. Celiac arteriogram indicates replaced left hepatic artery (black arrows) arising from left gastric artery. Black dotted arrows indicate right gastric artery. f. Replaced left hepatic artery (black arrows) selectively catheterized and embolized with microcoils. Right gastric artery was embolized with microcoils (black dotted arrow). g. Proper hepatic arteriogram from side hole (black arrowhead) of indwelling catheter shows whole hepatic arterial flow including right hepatic artery and the redistributed left hepatic artery (black arrows). h. CBCT-proper hepatic arteriogram shows contrast enhancement of the entire liver
