  1. aCTA, MRA, and CCT according to diagnostic pathway in stroke unite; bmassive intracerebral hemorrhage (ICH) described as distal MCA occlusion; cno ACA imaged and therefore 2 ICA occlusions or >80% stenosis with cross-filling missed; dcontrast through filter, and PCA described instead of MCA occlusion. CTA, computed tomography angiography; MRA, magnetic resonance angiography; CCT, cerebral computed tomography; ACA, anterior cerebral artery; ICA, internal carotid artery; MCA, middle cerebral artery; PCA, posterior cerebral artery.
