We report unusual 2 cases treated with Balloon-occluded transarterial chemoembolization (B-TACE) for peritoneal hepatocellular carcinoma (HCC) metastasis. An 87-year-old female with hepatitis-C related cirrhosis underwent radiofrequency ablation (RFA) repeatedly. Computed tomography showed a 30 mm diameter tumor seeding adjacent to the ascending colon. Digital subtraction angiography (DSA) of the gastroduodenal artery showed a tumor stain fed by an omental arterial branch distributing from the greater curvature of the stomach. Since ultraselective cannulation was difficult, a micro-balloon catheter was selected and advanced to the right gastroepiploic artery on the central side of the omental artery, and B-TACE was performed at this point. A 78-yearold male with hepatitis-C related cirrhosis underwent RFA and TACE repeatedly, but multiple HCC developed and a 45 mm diameter metastatic tumor adjacent to the descending colon was observed. DSA of the inferior mesenteric artery showed a tumor stain fed by the several peripheral branches of the left colic artery. Since one of this several branches was noted the normal mesenteric blood vessel by selective angiography, the position of the tip of the micro-balloon catheter was finely adjusted by balloon inflation to prevent inflow of the contrast medium into the normal blood vessel, and then B-TACE was performed.
