  		Fig. 3A —Case from 12-week follow-up. Three angiograms obtained before (A), just after (B), and 12 weeks after stent-graft placement (C) in dog in 12-week follow-up group. Stent is intact without any deformity or migration in follow-up angiogram. Transparent neointima covers all stent-grafts. This neointima was very thin (< 1 mm) and regular on gross (D) and microscopic (E) examination.
