AOL recanalization and TIMI reperfusion scoring sytem from IMS I review (after Khatri18)
| Score | AOL Recanalization | Score | TIMI Reperfusion |
|---|---|---|---|
| 0 | No recanalization of the primary occlusive lesion | 0 | No perfusion |
| I | Incomplete or partial recanalization of the primary occlusive lesion with no distal flow | 1 | Perfusion past the initial occlusion, but no distal branch filling |
| II | Incomplete or partial recanalization of the primary occlusive lesion with any distal flow | 2 | Perfusion with incomplete or slow distal branch filling |
| III | Complete recanalization of the primary occlusion with any distal flow | 3 | Full perfusion with filling of all distal branches, including M 3, 4 |
AOL indicates arterial occlusive lesion; TIMI, Thrombolysis in Myocardial Infarction.
