Representative images of gross specimens in the B-SEMS and C-SEMS groups. (a) Photographs showing extracted B-SEMS from the artery with glossy white thin neointima tissue. (b) Photographs showing extracted C-SEMS with mild thrombus on the inner and outer walls of the C-SEMS. (c) Thrombogenicity score in the C-SEMS group was significantly higher than in the B-SEMS group. Note CI, confidence interval; Note B-SEMS: bare closed-cell self-expandable metallic stent, C-SEMS: covered closed-cell self-expandable metallic stent; **: p < 0.01.
