Balloon-occluded retrograde transvenous obliteration of the intrahepatic portosystemic shunt was performed using N-butyl-2-cyanoacrylate and embolization coils. (A) The left inferior phrenic vein (white arrow) merged into the left hepatic vein (black arrow). (B) The left hepatic vein (black arrow) via a shunt (size: 10mm; white arrowhead) merged with the lateral inferior branch of the portal vein (P3). The left hepatic vein was occulted transiently with a balloon. (C) After the shunt was embolized with coils, the lateral superior branch of the portal vein (P2) also merged with the left hepatic vein via other shunts (size: 6mm; white arrowheads). (D) The shunt was embolized using coils.
