Fig. 1. COVID-19-related challenges in EVT workflows.
The figure illustrates how the COVID-19 pandemic is likely to influence endovascular treatment (EVT) for acute ischaemic stroke in the pre-hospital and in-hospital phases. CSC, comprehensive stroke centre; LVO, large vessel occlusion; mCTA, multiphase CT angiography; NCCT, non-contrast CT; PPE, personal protective equipment; PSC, primary stroke centre. aSee first figure in ref.4. bSee second figure in ref.4. cAs described and used in previous trials7–9. dFor a detailed description of EVT workflows in the neuroangiography suite, see ref.4. eSee ‘Postacute care’ section in ref.5. fPost-EVT neurological assessment schedule as proposed in ref.4.
