Categorias num relance

Cat.	Significado	Conduta	Risco	Fonte
0	No reperfusion No perfusion: no antegrade flow beyond the site of occlusion.	Represents failed reperfusion; supports continued thrombectomy attempts/rescue strategies as the angiographic goal is at least mTICI 2b-3 (the procedural endpoint).	Failed reperfusion (unsuccessful); associated with the worst functional outcomes.	okfonte Almekhlafi et al., 'Not All "Successful" Angiographic Reperfusion Patients Are an Equal Validation of a Modified TICI Scoring System,' PMC3971136, Table 1 / Methods, TICI 0 = 'No perfusion or anterograde flow beyond site of occlusion.'
1	Penetration without perfusion Penetration but not perfusion: contrast passes the initial obstruction but with only minimal filling of the distal (normal) territory.	Below the successful-reperfusion threshold; supports further thrombectomy passes/rescue toward the mTICI 2b-3 endpoint.	Considered unsuccessful reperfusion (minimal distal filling).	okfonte PMC3971136, Table 1 / Methods, TICI 1 = 'Penetration but not perfusion. Contrast penetration exists past the initial obstruction but with minimal filling of the normal territory.'
2a	Less than half reperfused Partial perfusion with distal branch filling of less than half (<50%) of the previously occluded artery's territory.	Falls short of the successful threshold (mTICI 2b); supports additional thrombectomy attempts where feasible to reach >=50% territory reperfusion.	Partial / generally considered incomplete (unsuccessful) reperfusion (<50% territory).	okfonte PMC3971136, Table 1 / Methods, TICI 2a = 'Some perfusion with distal branch filling of <50% of territory visualized.'
2b	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.	Meets the conventional 'successful reperfusion' threshold (mTICI 2b-3); commonly accepted as an adequate procedural endpoint, though 2c/3 is increasingly pursued.	Threshold commonly used (together with 2c and 3) to define 'successful' reperfusion (>=50% territory).	okfonte PMC3971136, Table 1 / Methods, TICI 2b = 'Substantial perfusion with distal branch filling of >=50% of territory visualized.'
2c	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.	Successful reperfusion; combined mTICI 2c/3 is the proposed optimal angiographic target of mechanical thrombectomy for the best functional outcomes.	Intermediate-but-favourable category; combined 2c/3 is the proposed target of mechanical thrombectomy.	okfonte 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.'
3	Complete reperfusion Complete perfusion: normal filling of all distal branches of the previously occluded vessel.	Optimal angiographic endpoint of thrombectomy; complete reperfusion, no further reperfusion attempts needed.	Best angiographic outcome; complete reperfusion, associated with the best functional outcomes.	okfonte PMC3971136, Table 1 / Methods, TICI 3 = 'Complete perfusion with normal filling of all distal branches.'
