Successful embolization of an intrahepatic portosystemic shunt using balloon-occluded retrograde transvenous obliteration: A case report

Figure 2 Superior mesenteric arterial portography image. A: Superior mesenteric arterial portography image shows communication between the right portal and hepatic veins (arrow); B: Connections between the right portal and hepatic veins are observed following the injection of contrast media via a micro-catheter that was advanced into the portal vein; C: The right hepatic vein is occluded by the balloon catheter to decrease the hepatofugal blood flow into the intrahepatic portosystemic shunt (IPSVS), and the IPSVS is observed with balloon-occluded retrograde right hepatic venography (arrow); D: Superior mesenteric arterial portography after the procedure shows that the IPSVS is sufficiently occupied by coils, and there is no residual hepatofugal blood flow into the IPSVS.
