Fig 3. Histologic evaluation of harvested aneurysms at 2 weeks (A–C) and 12 weeks (D and E).

A, Microphotograph showing attenuated inflammatory tissue within the aneurysm dome (H&E, original magnification x100).

B, Microphotograph showing attenuated spindle cells associated with some inflammatory cells within the aneurysm dome (H&E, original magnification x150).

C, Microphotograph showing that all spindle cells within the aneurysm dome are positive for SMA (immunohistochemistry, antibody for ${alpha}$ -SMA, original magnification x150).

D, Microphotograph showing highly vascularized fibrous tissue within the aneurysm dome (H&E, original magnification x60).

E, Microphotograph showing attenuated inflammatory cells associated with numerous thin-walled vessels within the aneurysm dome (H&E, original magnification x100).
