a 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.
b Histology grade for the partially thrombosed aneurysm dome and refers to the thrombosed portion of the dome.
