Usefulness of intra-procedural cone-beam computed tomography in modified balloon-occluded retrograde transvenous obliteration of gastric varices

Figure 2 Selective contrast-enhanced portal-venous phase axial computed tomography image. A: Selective contrast-enhanced portal-venous phase axial CT image of gastric varices in (A) pre-mBRTO with multiple transmural gastric varices in the gastric fundus, (B and C) selective 2D reconstructed CBCT images demonstrating multiple gelfoam/contrast filled gastric varices at a different slice confirming complete obliteration of corresponding gastric varices shown in (A). D: Selective contrast enhanced portal venous phase axial CT image 2-d post-mBRTO demonstrating non-enhancing/hypoenhancing gastric fundal wall consisted with completely thrombosed gastric varices consistent with findings of CBCT images. CT: Computed tomography; CBCT: Cone-beam CT; mBRTO: Modified balloon-occluded retrograde transvenous obliteration.
