Evaluation of mechanical thrombectomy outcomes in patients with low ASPECTS score

Takeaway

  • Patients with larger infarct volume may achieve positive mechanical thrombectomy (MT)-associated outcomes ≥6 hours from symptom onset, and those with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS) treated with MT who achieved successful recanalization were much more likely to achieve a favorable outcome than those with unsuccessful recanalization.

Why this matters

  • MT is associated with improved functional outcomes in patients with ASPECTS ≥6, but limited data are available concerning MT-associated outcomes in patients with lower ASPECTS scores.

  • This large cohort study suggests that patients with low ASPECTS scores may achieve short-term functional independence with MT, regardless of whether they are treated in the early or extended MT window, and has future treatment implications.
