Objectives: To describe clinical characteristics and computerized tomography signs of acute ischemic stroke patients in the first 6 hours after symptom onset. Subjects and methods: A description on clinical characteristics of acute ischemic stroke patients (history of disease, neurologic deficits of sudden onset, time of onset), early computerized tomography images signs, NIHSS scores, ASPECT scores was given to 134 patients suffering from acute ischemic stroke in the first 6 hours after symptom onset. | Journal of military pharmaco-medicine no8-2018 CLINICAL MANIFESTATIONS AND COMPUTERIZED TOMOGRAPHY CHARACTERISTICS OF ACUTE ISCHEMIC STROKE PATIENTS IN THE FIRST 6 HOURS AFTER SYMPTOM ONSET Nguyen Quang An1; Nguyen Minh Hien2; Nguyen Huy Ngoc3 SUMMARY Objectives: To describe clinical characteristics and computerized tomography signs of acute ischemic stroke patients in the first 6 hours after symptom onset. Subjects and methods: A description on clinical characteristics of acute ischemic stroke patients (history of disease, neurologic deficits of sudden onset, time of onset), early computerized tomography images signs, NIHSS scores, ASPECT scores was given to 134 patients suffering from acute ischemic stroke in the first 6 hours after symptom onset. Results: Average age: ± , from 21 85 years old. The average time was 213 minutes. Common history of disease: Hypertension () and atrial fibrillation (). Clinical manifestations included: Unilateral paresis (), aphasia () and facial palsy (91%). Consciousness was . Other characteristics included headache, dizziness and gaze preference took up low rate. The NIHSS score averages ± . In the computerized tomography image: of patients had a reduced contrast attenuation of the cerebral parenchyma, had large blood vessels occlusion, had a frontal cerebral artery. Average ASPECT scores ± . Clinical characteristics of the vertebrobasilar arterial system stroke were coma, dizziness. Signs of large vessel occlusion were coma, gaze preference and language disorders. Conclusions: Clinical symptoms of acute ischemic stroke patients in the first 6 hours were abundant, however the most common signs were unilateral paresis, facial palsy and language disorders. Nearly half of patients with acute ischemic stroke in the first 6 hours had no lesions on computerized tomography imaging. * Keywords: Acute ischemic stroke; Clinical manifestations; Computerized tomography
