FIGURE 2

Elastin staining of cross sections of aneurysm (A and C) and control left common carotid artery (LCCA) (B and D), demonstrating that the aneurysm has a larger cross sectional maximal diameter and has degeneration of the internal elastic lamina in the vessel wall compared with the control LCCA (original magnification, ×10 [A and B] and ×60 [C and D]). An elastic stain kit (Richard-Allen Scientific, Kalamazoo, MI) was used in which the internal elastic lamina stains black and can be seen intact in the LCCA as wavy bands (D).
