Modified Thrombolysis in Cerebral Infarction Revascularization Scale Score (mTICI Score)
0 No perfusion, complete obstruction; no flow past occlusion of “major” vessel
1 Perfusion past initial obstruction but limited distal branch filling with little/slow distal perfusion
2a Partial perfusion: < 50% of “major” vascular territory perfused (eg, filling and complete perfusion through one M2 division)
2b Partial perfusion: ≥ 50% of major vascular territory is filled, but there is not complete and normal perfusion of entire territory
3 Complete or full perfusion with filling of all distal branches
