FIG. 3.

TEVG implantation, in vivo imaging, and macroscopic observations at explantation. (a) Timeline summary of the implants performed, anticoagulation utilized therein, and in vivo monitoring used throughout the experimental duration. Acellular TEVG images (b) immediately postimplant, (c) 8 weeks, and (d) 24 weeks with yellow arrows indicating anastomoses. Angiogram images at (e) 8 weeks and (f) 24 weeks, with red arrows pointing to anastomoses. At explantation, (g) sham control (8 weeks) and TEVG were cut into rings at (h) 8 weeks and (i) 24 weeks. Grafts were monitored with ultrasonography for diameter, wall thickness, and flow characteristics at 1, 8, and 20 weeks, with (j) image of anastomotic site; (k) the measured diameter of sham control (Control, n=3) and grafts (TEVG, n=8) are shown near mid-graft (solid) and anastomoses (hashed). Statistical differences at p<0.05 are shown with paired symbols. Color images available online at www.liebertpub.com/tea
