The collateral map: prediction of lesion growth and penumbra after acute anterior circulation ischemic stroke

ConclusionPrecise prediction of lesion growth and penumbra can be possible using collateral maps, allowing for personalized application of recanalization treatments. Further studies are needed to generalize the findings of this study.Clinical relevance statementPrecise prediction of lesion growth and penumbra can be possible using collateral maps, allowing for personalized application of recanalization treatments.Key Points• Cell viability in cerebral ischemia due to proximal arterial steno-occlusion mainly depends on the collateral circulation.• The collateral map shows salvageable brain extent, which can survive by recanalization treatments after acute anterior circulation ischemic stroke.• Precise estimation of salvageable brain makes it possible to make patient-specific treatment decision.
