Columns 2 and 3, maximum percentage of total injected contrast material entering the aneurysm dome pre- and immediately poststent; 4, immediate poststent/prestent ratios of maximum CA volume entering the aneurysm dome; 5, follow-up angiographic grades: 0) intact aneurysm, 1) 0.75–0.50 filling, 2) 0.50–0.25 filling, 3) <0.25 filling, 4) no filling but exhibiting some remnant neck, 5) no CA flow in the aneurysm dome or neck (total occlusion); 6, conebeam micro-CT scanning result—thrombosed volume relative to total aneurysm dome volume (%)—total aneurysm occlusion; 7 and 8, histology grade for dome and neck20: 0) fresh blood clot or no thrombus, 1) organized thrombus in less than one-third of the area, 2) organized thrombus in one-third to two-thirds of the area, 3) organized thrombus in more than two-thirds of the area, 4) completely organized loose thrombus, 5) completely organized dense fibrous thrombus; 9 and 10, SEM grade for degree of endothelialization of stent and patch: 0) no cell coverage, 1) partial coverage with ECM and endothelial cells, 2) full coverage with ECM and endothelial cells, 3) full coverage with endothelial cells.
Histology grade for the partially thrombosed aneurysm dome and refers to the thrombosed portion of the dome.
