[Serial CT during arterial portography and arteriography of the liver with a triple-lumen balloon catheter].

Serial computed tomography during arterial portography (CTP) and CT during arteriography (CTA) of the liver could be performed on nine of ten patients with hepatocellular carcinoma, using triple-lumen balloon catheters (3-B-C). The 3-B-C was inserted into the common hepatic artery, and the balloon was inflated. We have injected contrast medium into the splenic artery through the side hole of the 3-B-C to perform CTP, and then into the common hepatic artery through the tip hole to perform CTA.
