Episode 333: 331. Noncontrast CT Selected Thrombectomy vs Medical Management

Noncontrast CT Selected Thrombectomy vs Medical Management for Late-Window Anterior Large Vessel Occlusion | Neurology Most studies that have shown a benefit from endovascular thrombectomy (EVT) for ischemic stroke in the late time window (6 to 24 hours after time last known well) have used either perfusion imaging or advanced imaging to identify core infarct volume. Whether plain CT alone can identify EVT candidates in the late time window is unknown. multinational cohort study that looked at Consecutive patients presenting within 6–24 hours of time last seen well with proximal anterior LVO stroke that were either selected for EndoVascular therapy by Noncontrast CT or medically managed  The primary outcome was 90-day ordinal shift on the modified Rankin scale. Symptomatic intracranial hemorrhage (sICH) and mortality at 90 days were key safety outcomes.  results Functional independence (mRS 0–2) was observed in 40% of the EVT group and 18% of the MM-alone group. Symptomatic ICH was nonsignificantly more common with EVT than with MM alone (8.5% vs. 1.4%), but overall mortality was lower with EVT (24% vs. 32%).
