Table 1:

Terminology and definition of TICI reperfusion (I) and AOL recanalization scores (II)*

Terminology and Definition

  1. Posttreatment TICI reperfusion grade

    0 = No perfusion

    1 = Perfusion past the initial obstruction but limited distal branch filling with little or slow distal perfusion

    2A = Perfusion of less than half of the vascular distribution of the occluded artery (eg, filling and perfusion through 1 M2 division)

    2B = Perfusion of half or greater of the vascular distribution of the occluded artery (eg, filling and perfusion through 2 or more M2 divisions)

    3 = Full perfusion with filling of all distal branches

  2. Posttreatment AOL recanalization grade

    0 = No recanalization of the occlusion

    1 = Incomplete or partial recanalization of the occlusion, with no distal flow

    2 = Incomplete or partial recanalization of the occlusion, with any distal flow

    3 = Complete recanalization of the occlusion with any distal flow

  • * The modified TICI reperfusion score was essentially equivalent to TIMI score applied in IMS I, with grade 2 further divided into A and B for post hoc analysis.
