Figure 1

A, Dissected left coronary artery from a 31-year-old male who died of head injuries. The artery shows no radiographic evidence of atherosclerosis. B-H are contiguous segments of the main left coronary artery, as labeled in A. B, Normal appearing intima (thin arrows) and media. C, Same coronary segment as B, but directly opposite on the other side of the lumen. The intima here is thicker (bracket), with a small focus of relative acellularity (open arrows). D, Slightly increased intimal thickening (bracket) and an increased area of acellularity (open arrows) compared to C. E, Marked increase in intimal thickness (bracket) with loss of tissue and cells (open arrows) consistent with focal degeneration. Lipid-laden SMCs (long arrows) surround this area of degeneration. F, Further increase in intimal thickness (bracket) with areas of acellularity and lipid-laden SMCs (long arrows). No areas of degeneration can be identified. G & H, Intimal thickening (bracket) is decreasing distally from F, but with more prominent and more numerous lipid-laden SMCs (long arrows). White asterisk = lumen, fat arrows = media. Hematoxylin & Eosin (H & E) stain in all photos.
