Abstract

Background: Acute ischemic stroke remains a leading cause of mortality and long-term disability worldwide. The relationship between clinical presentation and neuroimaging is crucial for severity stratification and prognosis. Objectives: To describe the clinical and neuroimaging characteristics of AIS patients and to analyze their association. Materials and methods: A crosssectional analytical study was conducted on 125 patients with AIS treated at Can Tho Central General Hospital. Results: The mean age was 65.7 ± 12.0 years, and females accounted for 51.2% of cases. Most patients (75.2%) were admitted within 24 hours of symptom onset. The most common clinical manifestations were hemiparesis (92.8%), central facial palsy (48.0%), and aphasia (40.8%). Moderate to severe stroke severity according to the National Institutes of Health Stroke Scale (NIHSS) was observed in 56.0% of patients. Significant associations were found between NIHSS severity and arterial occlusion site (p < 0.001) as well as infarct size (OR = 3.47; KTC 95%: 1.53 - 7.89; p = 0.002). Moderate to severe cases were predominantly associated with middle cerebral and internal carotid artery occlusion and lesions of ≥ 15 mm. Conclusion: The study has elucidated the clinical and neuroimaging characteristics of patients with acute ischemic stroke, thereby confirming the correlation between stroke severity assessed by the NIHSS, the site of arterial occlusion, and infarct size.
