Score | Thrombolysis In Myocardial Infarction (TIMI) scale | Modified Thrombolysis in Cerebral Infarction (TICI) scale |
---|---|---|
0 | No recanalization | No perfusion or anterograde flow beyond site of occlusion |
1 | Minimal recanalization | Contrast passes the area of occlusion but fails to opacify the entire cerebral bed distal to the obstruction during angiographic run |
2 | Partial recanalization | Partial perfusion wherein the contrast passes the occlusion and opacifies the distal arterial bed but rate of entry or clearance from the bed is slower than non-involved territories 2A: Partial filling only (<50%) of territory visualized* 2B: Partial filling ≥50% of territory is visualized† |
3 | Complete recanalization | Complete reperfusion with normal filling |
*2A is represented by partial filling, less than two-thirds of the ischemic territory, in the original TICI scale.
†2B is represented by complete filling that is slower than normal in the original TICI scale.
