|---|---|---|---|---|---|---|
| 1 | AcomA | 56/F | 5.9 | 5.24 | 0.77 | 15% |

| 4 | MCA | 41/M | 4.5 | 2.86 | 0.82 | 29% |
| 5 | PcomA | 57/F | 17.9 | 6.66 | 1.20 | 18% |
| 6 | BA | 50/F | 6.0 | 3.86 | 1.19 | 31% |
| 7 | MCA | 58/M | 12.8 | 6.79 | 0.70 | 10% |
| 8 | PA | 39/F | 6.1 | 3.76 | 1.20 | 32% |
| Average | 48 | 8.9 | 5.04 | 0.85 | 19% | |
| Minimum | 27 | 5.9 | 2.86 | 0.34 | 8% | |
| Maximum | 58 | 17.9 | 6.86 | 1.20 | 32% | |
| Standard deviation | 11 | 4.6 | 1.58 | 0.32 | 10% |
Note:—Aneurysm size is the largest aneurysm diameter. Neck diameters were measured in the working projection. AcomA indicates anterior communicating artery; BA, basilar artery; PA, pericallosal artery; PcomA: posterior communicating artery.
