Figure 1 Left lobe graft for biliary atresia in a 2-year-old boy. A: Hepatic venography shows severe blockage of the hepatic venous outflow. The pressure gradient between the right atrium and left vein was 13 mmHg. B: Hepatic venography after percutaneous transluminal venoplasty shows improved flow into the right atrium. The pressure gradient decreased to 3 mmHg.
