Kết quả điều trị bệnh nhân nhồi máu não cấp do tắc động mạch cảnh trong tại Trung tâm Thần kinh, Bệnh viện Bạch Mai

Objective: To evaluate the clinical outcomes of acute ischemic stroke secondary to internal carotid artery occlusion and to analyze factors associated with these outcomes.Materials and Methods: A cross-sectional descriptive study was conducted on 73 patients with acute ischemic stroke due to internal carotid artery occlusion who received treatment at the Neurology Center, Bach Mai Hospital, from August 2022 to August 2023.Results: In this cohort, males predominated (76.7%), and the mean age was 68.2 ± 11.6 years. The mortality rate was 12.3%, substantially higher than that reported in unselected ischemic stroke populations. The mean modified Rankin Scale (mRS) score was 3.8, with 63% of patients presenting with poor functional outcomes. Univariate analysis showed that age, sex, and common vascular risk factors were not significant predictors of outcome (p > 0.05). In contrast, lower ASPECTS scores and severe stenosis or occlusion of the M1 segment of the middle cerebral artery were strongly associated with unfavorable outcomes.Conclusion: Acute ischemic stroke caused by internal carotid artery occlusion is associated with high mortality and disability. Among the investigated variables, ASPECTS and M1 segment status emerged as the most important prognostic indicators of functional outcome.
