An 83 year-old male followed up for chronic hepatitis. (a) Coronal image of dynamic CT before chemoembolisation shows enhancing tumour (arrow) and a portosystemic shunt (arrowheads). (b) Volume rendering image based on abdominal dynamic CT showed a torturous shunt between the portal vein (P5) and the right hepatic vein (arrows). (c) Venography after balloon occlusion of one pathway of the portal vein hepatic vein shunt. The diameter of the right hepatic vein is 14  mm (arrow). The shunt was embolized using the Amplatzer Venous Plug II. (d) Venography after deploying the Amplatzer Venous Plug II; embolisation of the right hepatic vein is indicated (arrow). (e) Dynamic CT image 1 month after the procedure shows complete embolisation of the portal vein hepatic vein shunt (arrow).

Successful embolisation of the PV shunt was confirmed on abdominal dynamic CT that was performed 2  months after the embolisation (Figure 1).

A 75-year-old female: (a, b) Pretreatment dynamic CT and volume rendering image based on dynamic CT shows a tortuous shunt between the portal vein (P3) and the left hepatic vein (arrows). (c) Venography after catheterisation of the left hepatic vein. The diameter of the left hepatic vein is 7 mm (arrow). (d) Venography after deploying the AMPLATZER Vascular Plug II: embolisation of the left hepatic vein is shown, and embolisation of the right hepatic vein is indicated (arrow). (e) Dynamic CT 1 month after the procedure shows complete embolisation of the portal vein hepatic vein shunt (arrows).
