| Total aneurysm | Total (n=699) | AcoA group (n=427) | PcoA group (n=272) | P value |
| Aneurysm with follow-up (≥6 months) (n (%)) | 667 (95.4) | 408 (95.6) | 259 (95.2) | 0.84 |
| Follow-up duration (months) (mean±SD) | 20.4±12.7 | 20.8±13.0 | 19.8±12.2 | 0.34 |
| Recanalization (n (%)) | <0.01 | |||
| Stable occlusion | 556 (83.4) | 363 (89.0) | 193 (74.5) | |
| Minor recanalization | 72 (10.8) | 30 (7.4) | 42 (16.2) | |
| Major recanalization | 39 (5.8) | 15 (3.6) | 24 (9.3) |
