?
Objetivos de la imagen 1.-Descartar simuladores e ictus hemorrágicos
2.-Oclusión vascular 3.-Core y Penumbra
Emergency imaging before any treatment
Nonenhanced CT will provide necessary information
(Class I; Level of Evidence A)
TAC RM
If endovascular therapy is contemplated, a noninvasive intracranial vascular study is strongly recommended
(Class I; Level of Evidence A)
Patients should receive endovascular therapy with ICA or M1 occlusion
(Class I; Level of Evidence A)
Endovascular therapy may be reasonable M2-M3, ACA and posterior circulation
(Class IIb; Level of Evidence C)

The benefits of collateral measurement for selecting patients for endovascular therapy are unknown
(Class IIb; Level of Evidence C)
*Further trials may be helpful to determine if collateral status is beneficial for
ASPECTS <6 or beyond 6 hours

Conclusiones • CT basal y AngioTC obligatorio • Core / Penumbra pendiente de estandariación,
validación • Herramientas prometedoras para aumentar
ventana terapeútica y disminuir recanalización fútil
