Emergent CT angiography and risk of contrast-induced acute kidney injury in acute ischaemic stroke

Aktualności Neurologiczne, 2016
Objectives: Emergent computed tomography angiography with contrast is commonly performed for acute ischaemic stroke, but potentially delayed pending admission renal function assessment due to purported risk of contrast-induced acute kidney injury.

External Validation of Atherosclerotic Neuroimaging Biomarkers in Emergent Large‐Vessel Occlusion

Stroke: Vascular and Interventional Neurology, 2023
Background Intracranial atherosclerosis related large vessel occlusion (ICAS‐LVO) is the major cause of failed mechanical thrombectomy. ICAS‐LVO causes reocclusion or a fixed focal stenosis, leading to suboptimal revascularization and poor functional ...
