Nghiên cứu đặc điểm lâm sàng, hình ảnh học và kết cục chức năng của bệnh nhân nhồi máu não tuần hoàn sau tại Bệnh viện Đà Nẵng

To describe some clinical features, imaging features and functional outcome of patients with posterior circulation ischemic stroke. To evaluate of the correlation between clinical features, imaging and functional outcomes of patients with posterior circulation ischemic stroke. Subjects and methods: A cross-sectional descriptive study on 65 patients with acute posterior cerebral infarction hospitalized from March 2021 to June 2021 at Da Nang hospital. The extent of infarct lesions on brain imaging was assessed by pc-ASPECT score. Functional outcome was assessed by modified Rankin scale score at the time of hospital discharge and after 3 months. Results: Mean age 68.3 ± 12.7 years old. Male: 61.5%. 53.8% of patients were hospitalized after 24 hours. The most common clinical signs and symptoms were focal weakness (84.6%), dysarthria (64.6%), facial or lingual palsy (61.5%), swallowing disorder (27, 7%), decreased consciousness (26.2%), ataxia (16,9%), vertigo or dizziness (13,8%). The rate of basilar artery occlusion was 14% and the rate of patients with pc-ASPECTS score ≥ 8 was 8 81,5%. The rate of good functional outcome (mRS 0-2) after 3 months was 66.1%. Advanced age, prior history of ischemic stroke or transient ischemic attack (TIA), high NIHSS at admission, pc-ASPECT score < 8 are factors associated with poor functional outcome after 3 months. Conclusion: The clinical presentation of posterior cerebral infarction is diverse. Age, prior history of cerebral infarction or transient ischemic attack, NIHSS, and pc-ASPECTS is predictors of functional outcome.
