FIG 5. Angiogram shows the appearance of the side-wall venous-pouch aneurysm in a pig 21 days after embolization with a liner and one GDC. The appearances are consistent with complete obliteration of the aneurysm with healing of the neck. The distal marker ring of the liner can be seen as a dot to the left of the coil mass.
FIG 6. Gross specimen of the venous-pouch side-wall aneurysm. (The specimens are supported, for photography, by collars of modeling clay.)
A, The carotid artery has been opened to show the healed neck of the aneurysm represented by a small dimple (arrow).
B, The aneurysm has been sectioned longitudinally to show peripheral granulation tissue (arrow) and central unresolved blood clot within the interstices of the GDC. The liner material cannot be seen in the gross specimen.
