(a) Visceral phase angiography following injection of the splenic artery after occlusion of the portosystemic shunt with Amplatzer vascular plug (circled) demonstrates splenic vein (white arrows) draining antegrade into the portal vein (black arrows). (b) VR CT image shows the position of the Amplatzer plug (arrow) and successful embolization of the shunt (no longer visualized). Portal venous flow is now seen to and within the liver.
