Core Tip
Core tip: This is a retrospective study to evaluate the feasibility, usefulness and efficacy of cone-beam computed tomography (CBCT) in modified balloon-occluded retrograde transvenous obliteration (mBRTO) procedures including coil-assisted retrograde transvenous obliteration and plug-assisted retrograde transvenous oblitearation. With an intra-procedural three-dimensional CBCT, the technical success of mBRTO was determined prior to the completion of the procedure in 100% of cases. With CBCT, a complete anatomy of gastric varices including gastrorenal shunt, gastric varices, collaterals, afferent and efferent vessels were identified easily. The CBCT may improve the technical and clinical success of mBRTO procedures and potentially reduce additional procedure time and cost.
