Fig. 1A —43-year-old man with multiple liver metastases from rectal cancer. Arteriogram via port obtained after placement shows that all hepatic arteries are well visualized. Catheter tip was inserted into deep portion of gastroduodenal artery (long thin arrow), and side hole was placed in common hepatic artery (large arrowhead). To prevent extrahepatic influx of anticancer agents, gastroduodenal artery (thick arrow), right gastric artery (small arrow), and posterior superior pancreatoduodenal artery (small arrowhead) were embolized with microcoils. Embolization of gastroduodenal artery was performed using mixture of n-butyl cyanoacrylate and iodized oil in addition to microcoils to fix catheter and occlude arteries.
