Figure 2 Photomicrograph of the non-stented coronary artery of Patient #2 just proximal to the stent showing severe stenosis and non-occlusive luminal thrombus (th) (A). In B is shown the proximal stented artery with marked inflammatory reaction around stent struts; high-power magnification of the boxed areas in B is shown in C and D, note that there is severe granulomatous reaction consisting of macrophages (arrowheads) and giant cells (arrows). In between the stent struts, there is severe eosinophilic and T-cell infiltration (high-power E) with only rare spindle-shaped cells seen close to the lumen. There is absence of endothelium in D; instead there is a surface thrombus.
