No reperfusion

No perfusion: no antegrade flow beyond the site of occlusion.

CondutaRepresents failed reperfusion; supports continued thrombectomy attempts/rescue strategies as the angiographic goal is at least mTICI 2b-3 (the procedural endpoint).

RiscoFailed reperfusion (unsuccessful); associated with the worst functional outcomes.

Penetration without perfusion

Penetration but not perfusion: contrast passes the initial obstruction but with only minimal filling of the distal (normal) territory.

CondutaBelow the successful-reperfusion threshold; supports further thrombectomy passes/rescue toward the mTICI 2b-3 endpoint.

RiscoConsidered unsuccessful reperfusion (minimal distal filling).

3 de 6

Less than half reperfused

Partial perfusion with distal branch filling of less than half (<50%) of the previously occluded artery's territory.

CondutaFalls short of the successful threshold (mTICI 2b); supports additional thrombectomy attempts where feasible to reach >=50% territory reperfusion.

RiscoPartial / generally considered incomplete (unsuccessful) reperfusion (<50% territory).

verificadoRecommendations on angiographic revascularization grading standards (mTICI)PMC3971136, Table 1 / Methods, TICI 2a = 'Some perfusion with distal branch filling of <50% of territory visualized.'

4 de 6

More than half reperfused

Substantial partial perfusion with distal branch filling of half or more (>=50%) of the occluded artery's territory, but short of complete.

CondutaMeets the conventional 'successful reperfusion' threshold (mTICI 2b-3); commonly accepted as an adequate procedural endpoint, though 2c/3 is increasingly pursued.

RiscoThreshold commonly used (together with 2c and 3) to define 'successful' reperfusion (>=50% territory).

Near complete

Near-complete perfusion: filling is essentially complete except for slow flow in a few distal cortical vessels, or the presence of small distal cortical emboli.

CondutaSuccessful reperfusion; combined mTICI 2c/3 is the proposed optimal angiographic target of mechanical thrombectomy for the best functional outcomes.

RiscoIntermediate-but-favourable category; combined 2c/3 is the proposed target of mechanical thrombectomy.

verificadoRecommendations on angiographic revascularization grading standards (mTICI)PMC3971136, Table 1 / Methods, TICI 2c = 'Near complete perfusion except for slow flow in a few distal cortical vessels, or presence of small distal cortical emboli.'

6 de 6

Complete reperfusion

Complete perfusion: normal filling of all distal branches of the previously occluded vessel.

CondutaOptimal angiographic endpoint of thrombectomy; complete reperfusion, no further reperfusion attempts needed.

RiscoBest angiographic outcome; complete reperfusion, associated with the best functional outcomes.

verificadoRecommendations on angiographic revascularization grading standards (mTICI)PMC3971136, Table 1 / Methods, TICI 3 = 'Complete perfusion with normal filling of all distal branches.'
