Fig 4 Whole-mount example histophotomicrographs of overlapped bare metal stent (BMS) or drug-eluting stent (DES) in porcine iliac arteries after 3 months (left panels), 6 months (middle panels), and 12 months (right panels). Sections are stained with toluidine blue and basic fuchsin.

Fig 5 Histologic examples of stent-inducted neoatherosclerosis. a, Bare metal stent (BMS) at 3 months. Note the presence of severe neoatherosclerosis, including cholesterol clefts visible as void spaces, surrounding foamy cell accumulation, and fat infiltration. b, BMS at 6 months. c, BMS at 12 months. d, Drug-eluting stents (DES) at 12 months. Sections were stained with toluidine blue basic fuchsin.
