Abstract:
Objective To investigate the relationship between vertebrobasilar artery tortuosity and vasogenic dizziness/vertigo-related cerebral infarction in the elderly.Methods A total of 160 elderly patients with vasogenic dizziness/vertigo-related cerebral infarction admitted to the Department of Neurology of Taiyuan Xishan Hospital from January 2022 to October 2023 were selected.The patients were divided into tortuous group and non-tortuous group,80 cases in each group,according to the presence of vertebrobasilar artery abnormality by magnetic resonance angiography.The general clinical data,vascular disease risk factors,and the expanded-National Institutes of Health stroke scale(e-NIHSS)score of two groups were compared.The tortuous group was divided into simple abnormality group and mixed abnormality group according to vertebrobasilar artery morphology,and the degree of influence on related cerebral infarction was analyzed.Results The proportion of hypertension,vertebral artery dominance,smoking history and e-NIHSS score in ortuous group were significantly higher than those in non-tortuous group(P＜0.05).Multivariate Logistic regression analysis showed that history of hypertension,vertebral artery dominance,and smoking history were independent risk factors for elderly patients with vasogenic dizziness/vertigo-related cerebral infarction with vertebrobasilar artery abnormality(P＜0.05).54.3％of patients in simple abnormality group were moderate to severe stroke patients,and 58.8％of patients in mixed abnormality group were moderate to severe stroke patients,and there was no statistical significance between two groups(x2=0.029,P=0.864).Conclusion History of hypertension,vertebral artery dominance,and smoking history were independent risk factors for vasogenic dizziness/vertigo-related cerebral infarction in elderly patients with vertebrobasilar artery tortuosity,and these patients had higher neurological deficit scores.
