| 1 (sacrificed at 1 year) |
6.3×7.8 | ↓ | Partially opacified |
0 | occluded | 0 | Coil ball shrunken, "healing line" emerged |
0 | healing line became more evident |
The whole stent was covered by thin, smooth, glossy and semitransparent neointima formation at 1 year |

The same as case 1 at 1 year |
| 3 (sacrificed at 2 days) |
5.8×5.9 | ↓ | Partially opacified |
The aneurysm lumen was full of thrombus. No visible thrombus or tissue adhering to stent wall |
||||||
| 4 (sacrificed at 1 month) |
6.9×6.3 | ↓ | Partially opacified |
0 | occluded | Thrombosis within the aneurysm. The neck was covered by neointima except several small pores among the stent and the coil still open. |
