A representative Verhoeff-Van Gieson (VVG)-stained longitudinal section of a 39-year-old TA demonstrating the algorithm of counting the elastic lamellae along the length of the blue lines drawn across the tunica media. Green circles on the lines illustrate the elastic lamellae that are counted along each line. Note that interlamellar fibers were not counted. Verhoeff-Van Gieson (VVG) stain: elastin is black, collagen is red, smooth muscle is brown.
