Relationship between cerebrovascular collaterals and stroke outcomes in children treated with thrombectomy: Save ChildS


  • Favorable cerebrovascular collaterals are associated with improved neuroradiological outcomes, but not with better clinical outcomes, in children with ischemic stroke undergoing thrombectomy.

Why this matters

  • The role of collateral circulation in children with ischemic stroke has not been well studied.

  • This study provides evidence that favorable collaterals likely do not have a marked impact on clinical outcomes in children, thus are of limited importance in treatment decisions.
