Transpancreatic catheterization of the right hepatic artery for chemoembolization using a new infusion system.

The right hepatic artery was catheterized for chemoembolization in a patient with liver-dominant metastatic breast carcinoma and occlusion of the celiac artery by tumor compression. This was accomplished by use of a new coaxial infusion catheter-steerable guidewire system passed through the superior mesenteric artery and posterior pancreatic arcade.
