Patient 3 sample acquisition, histomorphology and 3D histology. CT-angiogram demonstrates the approx. site of samples acquisition. The arrow marks the aneurysm sac incision during open repair. The histologic photos (upper panel) show a complete circular preparation of the aneurysm sac for HE and four representative cutouts demonstrating a differing histomorphology (lumen orientated upwards). The lower panel demonstrates 3D histology HE representative images. The slide image background was removed based on color similarity to white and then set to be transparent. This enables the interactive exploration of the internal structures. Zooming in the 3D histology visualization highlights the large differences between the horizontal resolution of up to 0.25 um/pixel and the vertical axis. Samples are oriented mirrored with the CT-angiogram. (A = anterior, P = posterior, R = right, L = left, H = head, T = tail) (scale bar 2 mm for overview and 250 µm for blow-ups)
