Results of anterior cerebral artery visualization by cross flow and the balloon test occlusion outcome
| ACA visualization | BTO-positive (%) | BTO-negative (%) | Total (%) | |
| Poor | Grade 0 | 2 (5) | 0 (0) | 2 (5) |
| Grade 1 | 0 (0) | 0 (0) | 0 (0) | |
| Grade 2 | 1 (2) | 1 (2) | 2 (5) | |
| Good | Grade 3 | 0 (0) | 5 (12) | 5 (12) |
| Grade 4 | 2 (5) | 31 (74) | 33 (78) | |
| Total | 5 (12) | 37 (88) | 42 (100) | |
Significant differences (P = 0.0051; 95%CI: 0.13-7.61) was seen between the ACA visualization and the BTO outcome. ACA: Anterior cerebral artery; BTO: Balloon test occlusion.
