FIGURE 5.

Histology from frozen sections of human intracranial thrombus retracted from a patient with advanced carotid atherosclerosis and explored by polarization filter reflected light microscopy. (A and B) Hematoxylin-stained sections with easily identifiable birefringent CC marked with orange arrows. (C and D) HES-stained sections of corresponding areas. Corresponding areas are (A) and (D), and (B) and (C). The thicknesses of the sections are 4 μm. Images were taken with original magnification ×40 objective by a polarization filter to visualize birefringent structures. Scale bar, 30 μm.
