Figure 11a. Treatment of a type B-3 gastric varix with retrograde injection of an NBCA-lipiodol mixture. (a) Contrast-enhanced CT scan shows fundal gastric varices. (b) Splenic venogram shows that the varices drain through the gastrocaval shunt (arrows). (c) Balloon-occluded venogram obtained after coil embolization of collateral vessels demonstrates residual high-flow collateral vessels. The microcatheter was advanced farther into the varices, and 4 mL of NBCA-lipiodol mixture was injected via the microcatheter. (d) Fluoroscopic image obtained immediately after injection shows that the NBCA-lipiodol mixture fills the varices well. (e) CT scan obtained 2 weeks later shows NBCA-lipiodol mixture in the varices.
