## Categorias

| Código | Rótulo | Critérios | Conduta | Risco | Localizador | Verificado |
| --- | --- | --- | --- | --- | --- | --- |
| 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. | 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). | 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). | 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). | 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. | 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. | PMC3971136, Table 1 / Methods, TICI 3 = 'Complete perfusion with normal filling of all distal branches.' | ✓ |
