? 2021 Elsevier Inc.Background: Quick identification of patients with mild ischemic stroke complaining of dizziness from other patients with benign peripheral vestibular disorders who also experience dizziness in the emergency department (ED) may be difficult. Decision-making on intravenous thrombolysis therapy (IVT) in patients whose chief symptoms include acute dizziness or vertigo remains a severe challenge for ED physicians. This study evaluated the diagnosis, treatment processes and the short-term outcomes in patients with mild vestibular stroke in the ED. Methods: A total of 89 consecutive patients with mild ischemic stroke primarily presenting with vestibular symptoms, who arrived at ED within 4.5 after onset, and were admitted at the stroke center of Zhejiang Provincial People's Hospital between January 2015 and March 2021 were retrospectively enrolled. Patients treated with IVT (n = 47) were compared to patients without IVT (n = 42) in terms of demographics, onset-to-door time (ODT), baseline clinical characteristics, risk factors of stroke, imaging findings, and short-term outcomes. The correlation between these parameters and IVT decision-making was analyzed. Results: Patients in IVT group more frequently presented with shorter ODT, focal neurological deficits (dysarthria, facial palsy, hemiglossoplegia, hemiparesis, hemisensory loss), disabling deficits, higher baseline National Institute of Health Stroke Scale (NIHSS) scores, and underwent multi-mode imaging before a decision. A higher proportion of isolated vestibular symptoms, acute transient vestibular syndrome, and vestibulo-vagal symptoms were found in the no-IVT group. There were no differences in demographics between the two groups. ODT was negatively correlated with the decision-making on IVT, and baseline NIHSS scores were positively correlated with the decision-making on IVT. Conclusion: ODT and baseline NIHSS scores were correlated with the IVT decision in mild stroke patients primarily presenting with vestibular symptoms. Severe vestibular symptoms and disabling deficits were weakly associated with IVT decision, while the vestibulo-oculomotor signs and multi-mode imaging did not result as the influencing factors promoting the IVT decision-making for mild vestibular stroke.
