  		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.

  		Fig. 1B —43-year-old man with multiple liver metastases from rectal cancer. Arteriogram via port obtained 4 months after placement shows that splenic artery (arrow) is better visualized than hepatic arteries because of catheter dislodgement (arrowhead).

  		Fig. 1C —43-year-old man with multiple liver metastases from rectal cancer. Arteriogram via port obtained after replacement shows that all hepatic arteries are well visualized again. Catheter tip was inserted into peripheral branch of hepatic artery (arrow), and side hole was placed in common hepatic artery (arrowhead).

  		Fig. 2A —33-year-old woman with multiple liver metastases from breast cancer. Celiac arteriogram obtained after occlusion of implanted catheter (long thin arrow) shows that hepatic arteries are well visualized. Gastroduodenal artery (thick arrow), posterior superior pancreatoduodenal artery (arrowhead), and right gastric artery (small thin arrow) were embolized with microcoils to prevent extrahepatic influx of anticancer agents.

  		Fig. 2B —33-year-old woman with multiple liver metastases from breast cancer. Arteriogram via port obtained after replacement shows that all hepatic arteries can be visualized. Catheter tip was inserted into peripheral branch of hepatic artery and side hole was placed in common hepatic artery (arrowhead). Origin of right hepatic artery (arrow) was not visualized because of stenosis caused by tip of original catheter, but right hepatic artery is well visualized because of blood supply via left hepatic artery through intrahepatic arterial anastomoses.

  		Fig. 2C —33-year-old woman with multiple liver metastases from breast cancer. Arteriogram via port obtained 1 week after replacement shows that splenic artery (arrowhead) is better visualized than hepatic arteries because of catheter dislodgement (arrow).

  		Fig. 2D —33-year-old woman with multiple liver metastases from breast cancer. Arteriogram via port obtained after second removal and replacement shows that hepatic arteries are well visualized. Catheter tip (arrow) was inserted into another peripheral branch of hepatic artery.
