A Contrast-enhanced abdominal CT angiography with three-dimensional reconstruction showed a smooth liver surface, splenomegaly and gastroesophageal varices (white arrow). B Hepatic vein-to-vein communication was detected by hepatic venography. C Portography showed irregularity and tortuosity of the peripheral portal branches with much abrupt interruptions (black arrow) and avascular area beneath the liver surface. Portovenous collaterals (white arrows) derived from gastric coronary vein were also displayed. D Post-TIPS portography revealed embolization of collaterals and clear stent flow from portal vein to systemic circulation
