Figure 1a. Images in a 54-year-old man with a Klatskin tumor. (a) Anteroposterior main portal venogram obtained before embolization of the right portal venous branches. (b) Anteroposterior abdominal conventional radiograph obtained after right portal vein embolization. Note radiopaque Embol-78 (arrowheads) in the right portal venous branches. (c) Anteroposterior direct portal venogram obtained after embolization shows a total occlusion (arrow) of the portal venous branches in the right lobe. (d) CT scans obtained before embolization show patent right (arrows) and left (arrowheads) portal venous branches. (e) CT scans obtained 2 weeks after portal vein embolization show complete occlusion of the right anterior and posterior portal venous branches. Note radiopaque embolic material in the right portal venous branches (arrowheads).
