Schematic representation shows modification of the ipsilateral technique for RPVE extended to segment 4. (A) Placement of a 6F vascular sheath into the right portal branch. An angled 5F catheter is placed into the left portal system with coaxial placement of a microcatheter into a segment 4 branch. Particulate embolization is performed, followed by placement of coils, until all the branches are occluded. (B) After segment 4 embolization is completely occluded, a 5F reverse-curve catheter is used for RPVE. (C) After PVE is complete, the access tract is embolized with coils and/or gelfoam to prevent subcapsular hemorrhage.
