Zhang et al reported a score for predicting intracranial hemorrhage after endovascular treatment of an ischemic stroke. The authors are from multiple institutions in China.
ACTS is an acronym for ASPECTS, collateral flow, TOAST and sugar.
Patient selection: endovascular therapy for an ischemic stroke
Parameters:
(1) ASPECTS (Alberta Stroke Programme Early CT Sscore), from 0 to 10
(2) collateral flow
(3) TOAST etiological subtype
(4) blood glucose on admission in mmol/L
