Overview

Retrospective analysis reveals collateral circulation predicts outcomes in acute ischemic stroke, suggesting importance of mCTA over ASPECTS.

Key Points

  • The initial collateral circulation score from mCTA significantly relates to clinical outcomes in acute ischemic stroke, emphasizing its role.
  • Univariate analysis showed that both collateral scores and first phase CTA ASPECTS associate with patient outcomes post-stroke discharge.
  • Analysis of 300 patients indicated only the first phase CTA ASPECTS emerged as a significant predictor of discharge mRS.
  • The findings suggest that aggressive reperfusion therapies may not be necessary for all patients with good collateral scores.
