(A) Balloon-occluded retrograde transvenous venogram using 20 ml carbon dioxide gas showing the entire gastric varices in the posterior–anterior view. (B) Balloon-occluded retrograde transvenous obliteration using polidocanol foam (left anterior oblique view). (C) Gastrorenal shunt (left inferior phrenic vein) embolized using 2.5 ml of 40% n-butyl cyanoacrylate (NBCA)-Lipiodol (arrow) in the left anterior oblique view. The NBCA glue is injected into the most dorsally located gastrorenal shunt a few centimeters above the balloon tip through the same microcatheter. (D) The NBCA glue (arrow) is confirmed to be fixed even after the balloon deflation (posterior–anterior view).
