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

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

BackgroundIntracranial 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 outcomes. We aimed to externally validate 4 preide...

Zusammenfassung:BackgroundIntracranial 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 outcomes. We aimed to externally validate 4 preidentified imaging biomarkers of ICAS‐LVO: absent hyperdense sign, Hounsfield units (Hu ratio ≤1.1 and Delta Hu
