Abstract

Abstract: Objective To deepen the understanding of acute cerebral infarction with the onset of isolated vertigo. Methods We retrospectively analyzed the patients with the onset of isolated vertigo that were previously treated in Department of Neurology, China Civil Aviation General Hospital. They were divided into acute cerebral infarction group(25 cases in the case group) and non-acute cerebral infarction group(25 cases in the control group). The demographic characteristics, risk factors of cerebrovascular disease and imaging characteristics were analyzed. Results In the case group, the proportions of males and the patients who were over 55 years old were significantly higher than those of control group (72% vs 44% and 80% vs 52%, respectively, P<0.05 ). The proportions of patients with hypertension and diabetes in the case group were higher than those in the control group(72% vs 56%, 52% vs 40%, respectively), and the proportion of patients with hyperlipidemia was lower than those in the control group (84% vs 96%). There was no significant difference between the two groups(P＞0.05). The proportions of clinical manifestations with nausea, vomiting, hearing loss and nystagmus in the case group were higher than those in the control group (68% vs 56%, 52% vs 40%, 16% vs 4%, and 24% vs 16%, respectively), while the proportion of tinnitus was lower than that in the control group (8% vs 16%). There was no significant difference between the two groups (P >0.05). In the case group, there were 18 cases（72%） of cerebellar infarction, 5 cases（20%） of brainstem infarction, 1 case（4%） of occipital lobe infarction and 1 case（4%） of hippocampus infarction. Conclusion Among patients with acute cerebral infarction who started with isolated vertigo，Men had a significantly higher risk of acute cerebral infarction than women, and patients over 55 years old had a significantly higher risk than the adult patients under 55 years old. 2.Head magnetic resonance imaging showed most of the infarction sites were in the blood supply area of the vertebrobasilar artery system: located mainly in the cerebellum and brainstem.
