Evolution of 76 cerebral aneurysms treated with Neuroform stent system−assisted coiling
| Immediate Postoperative | First Follow-Up (6.54 ± 1.56 mo) | Second Follow-Up (16.41 ± 3.83 mo) | Third Follow-Up (37.09 ± 9.6 mo) | |
|---|---|---|---|---|
| Complete occlusiona | 24 (31.6%) | 37 (63.8%) | 44 (64.7%) | 26 (56.5%) |
| Neck remnant | 20 (26.3%) | 7 (12.1%) | 9 (13.2%) | 6 (13.0%) |
| Residual aneurysm | 32 (42.1%) | 14 (24.1%) | 9 (13.2%) | 7 (15.2%) |
| Recanalization | 0 | 0 | 6 (8.8%) | 7 (15.2%) |
| Total | 76 | 58 | 68 | 46 |
a The rates of complete occlusion on the immediate postoperative angiograms are statistically different from the results observed at the first (P < .01), second (P < .01), and third (P < .01) follow-up terms. The percentage of complete occlusion is relatively stable after the first follow-up examination, without statistical differences between the first and second follow-up terms (P = .91), the first and third follow-up terms (P = .45), or the second and third follow-up terms (P= .37).
