Abstract

Objective: To describe the computed tomography imaging features of acute ischemic stroke patients with intracerebral arterial occlusion within 6 hours from onset. Subject and method: 123 acute ischemic stroke patients with intracerebral arterial occlusion onset within 6 first hours were enrolled from 11/2016 to 2/2018 at Emergency Department, 108 Military Central Hospital. Noncontrast computed tomography (NCCT) and computed tomography angiography (CTA) were used to investigate the early infarct signs and calculate the Alberta stroke program early CT score (ASPECTS). Result: Mean time from symptoms onset was 205.4 ± 92.4 minutes, the average age of patients was 65.0 ± 11.5 and the proportion of male accounted for 56.9%. The prevalence of early CT signs of brain infarction was 71.5%. Neuroimaging of these patients without focal parenchymal hypoattenuation made up 26.8%. On CTA, large artery occlusions represented 63.4% and 79.7% of these belonged to anterior circulation. Mean ASPECTS of patients with middle cerebral artery (MCA) occlution was 7.75 ± 1.82 point. Conclusion: Patients with ischemic stroke within 6 first hours often have at least one of the early infarct signs. The large artery occlusions made up 63.4%. Mean ASPECTS of patients with MCA occlution was 7.75 ± 1.82 point.
