FIG. 3.

Computed tomography (CT) analysis of TEVG implanted in lamb model. Serial CT imaging was used to assess the change in size and shape of the TEVG implanted in juvenile lambs over a 6-month time course. All surviving animals were serially imaged at early (2 months) and late (6 months) time points. At the early time point, the TEVG showed thickening of the graft wall accompanied in some instances by graft luminal narrowing (n=11). There was no radiographic evidence of thrombosis in any graft. The graft luminal volume increased over the course of the experiment in all (n=9) animals that survived the 6-month time course. There was no radiographic evidence of aneurismal dilation in any grafts. Arrows show implanted graft by horizontal CT slice. “J” shows parts of implanted grafts by long-axis CT slice.
