anterior lesions involved the complete territory of the middle cerebral artery (MCA), posterior cerebral artery, or anterior cerebral artery or were in 2 cortical superficial branches of the MCA, in a cortical superficial branch of MCA associated with the MCA deep branch, or in >1 artery territory (e.g., MCA associated with anterior cerebral artery territory); lesions ≥1.5 cm in the brain stem or cerebellum.
infarct size ≥ 3 cm.
