Fig 2. Photomicrographs illustrating dome healing. All sections were stained with H&E.
A, Representative section (magnification x20) of a dome score = 0, showing that the aneurysm cavity is completely filled with unorganized thrombus.
B, Representative section (magnification x15) when the dome score = 1, where less than one third of aneurysm cavity is filled with organized tissue.
C, Representative section (magnification x20) with dome score = 2, in that approximately one half of the aneurysm cavity is filled with organized tissue.
D, Representative section (magnification x15) with a dome score = 3, most the aneurysm cavity filled with organized tissue; a residual small area of unorganized thrombus is also evident.
E, Representative section (magnification x15) with the dome score = 4, showing the aneurysm cavity to be entirely filled with loose organized tissue.
F, Representative section (magnification x40) with the dome score = 5. Staining in this section reveals the aneurysm cavity is completely filled with attenuated cellular tissue.
