Fig. 4A 41-year-old man with hepatic vein stenosis of right graft.
Axial portal venous phase CT scan obtained on 9th postoperative day shows
homogeneous enhancement pattern of both grafts. In contrast to
normal-appearing anastomotic site of left-graft hepatic vein (curved
arrow), there is short segmental slit like narrowing at anastomotic site
of right-graft hepatic vein (arrows) with prestenotic dilatation.
Ratio of diameter of preanastomotic segment to that of anastomotic segment is
greater than 2.0. Therefore, focal narrowing of right graft hepatic vein is
determined to be present.
