Proposed revised Thrombolysis In Cerebral Infarction scale (TICI) scale including a 2C designation

ScoreRevised TICI
0No perfusion or anterograde flow beyond site of occlusion
1Penetration but not perfusion. Contrast penetration exists past the initial obstruction but with minimal filling of the normal territory
2Incomplete perfusion wherein the contrast passes the occlusion and opacifies the distal arterial bed but rate of entry or clearance from the bed is slower or incomplete when compared with non-involved territories
 2ASome perfusion with distal branch filling of <50% of territory visualized
 2BSubstantial perfusion with distal branch filling of ≥50% of territory visualized
 2CNear-complete perfusion except for slow flow in a few distal cortical vessels or presence of small distal cortical emboli
3Complete perfusion with normal filling of all distal branches
