Figure 1 Sequential computed tomography (CT) scans demonstrating progressive occlusion of an interposed Hemashield graft. Liver CT images were obtained at postoperative day 7 (A), 1 month (B), 6 months (C), and 12 months (D) after transplantation. By 6 months (C), the middle hepatic vein outflow was nearly obstructed, although hepatic venous congestion did not occur owing to the development of intrahepatic collateral channels. At 12 months (D), the graft lumen appeared completely thrombosed. Yellow arrows indicate residual flow within the graft, whereas red arrows mark thrombotic occlusion.
