Evaluation of clot burden and distribution using time-resolved C-arm CBCTA data
| Case | Side | Proximal Occlusion Site | Distal Occlusion Site | Thrombus Length (mm) | Clot Burden Score | Diameter of Distal Vessel (mm) |
|---|---|---|---|---|---|---|
| 1 | R | Proximal M1 | Proximal M2 | 24.8/20.9a | 6 | 1.0/1.7a |
| 2 | L | Distal M1 | MCA bifurcation | 7.0 | 8 | 1.7 |
| 3 | L | Distal M1 | Proximal M2 | 3.2 | 7 | 2.1 |
| 4 | R | ICA terminus | Proximal M1 and A1 | 6.8 | 5 | 2.7 |
| 5 | L | Cavernous ICA | MCA bifurcation | NA | 3 | 2.5 |
| 6 | L | Cervical ICA | Supraclinoid ICA | NA | 7 | 3.7 |
| 7 | L | Cervical ICA | ICA terminus | NA | 7 | 2.7 |
| 8 | R | Distal M2 | Distal M2 | 9.6/6.1a | 9 | 1.2/1.8a |
| 9 | R | Distal M2 | Distal M2 | 9.2 | 9 | 1.3 |
| 10 | NA | Upper basilar trunk | L-P1 | 11.9 | NA | 2.6 |
Note:—R indicates right; L, left; NA, not applicable.
↵a The clot is located in a bifurcation site, where there are 2 distal ends and subsequently 2 measurements for both thrombus length and diameter of the distal vessel.
