Fig. 6. — Preoperative portal vein embolization for hilar cholangiocarcinoma

A. A 4-F pigtail catheter was advanced into the portal vein via the left portal branch and portography was performed. B. A balloon catheter was advanced into the posterior branch of the right portal vein and a fibrin glue mixed with iodized oil was injected under balloon occlusion. C. Thereafter, the fibrin glue was also injected into the anterior branch of the right portal vein under balloon occlusion. D. Portography performed immediately after portal vein embolization (PVE) showed complete occlusion of the right portal vein. E. Unenhanced CT performed 1 week after PVE showed the fibrin glues mixed with iodized oil in the right portal branches.
