mTICI Grades | Definitions |
---|---|
Grade 0 | No perfusion |
Grade 1 | Antegrade reperfusion past the initial occlusion, but limited distal branch filling with little or slow distal reperfusion |
Grade 2a | Antegrade reperfusion of less than half of the occluded target artery previously ischemic territory (eg, in 1 major division of the MCA and its territory) |
Grade 2b | Antegrade reperfusion of more than half of the previously occluded target artery ischemic territory (eg, in 2 major divisions of the MCA and their territories) |
Grade 3 | Complete antegrade reperfusion of the previously occluded target artery ischemic territory, with absence of visualized occlusion in all distal branches |
MCA indicates middle cerebral artery; and mTICI, Modified Treatment in Cerebral Ischemia Scale.
