The purpose of this study is to determine the safest method of radioembolization (treatment of your liver tumors by the delivery of radiation beads directly into the blood supply of the liver tumors) by examining the use of two different catheter systems. Currently, there is no one standard way to deliver these radiation beads. This study will evaluate two different methods to assure safety.

The conventional system is a catheter with an end hole that cannot stop reflux (when the injected material moves away from its intended delivery location.)  Therefore with the conventional system, an additional procedure is performed where permanent plugs are placed in the artery to the stomach to prevent spillage of radiation beads into the stomach and pancreas.

Recently, there has been the introduction of catheters that prevent reflux and therefore can potentially save the additional step of placing permanent plugs into the blood vessels.

In this study, you will be randomly selected to receive a end hole catheter with placement of a permanent coil to plug the artery leading to your stomach (gastroduodenal artery - GDA) or the use of anti-reflux catheter (Surefire Infusion System) without placement of permanent plugs.

You may qualify to take part in this research study because you have a liver tumor and your physician has recommended you to receive radioembolization as treatment.
