전정신경염에서 추골동맥 병변의 임상적 의의

Abstract

Background and Objectives: The etiology of vestibular neuritis (VN) is elusive, however viral infection and vascular ischemia are considered as major cause of VN. The aims of the present study were to evaluate relationships between vertebrobasilar artery status and VN. Materials and Methods: Patients who received treatment for VN from April 2014 to October 2019 were enrolled. All subjects underwent vestibular function tests of caloric test, cervical vestibular evoked myogenic potential test and magnetic resonance imaging (MRI) angiography. Vertebral artery (VA) lesions were defined as vertebral hypoplasia and vertebral stenosis. Results: A total of 130 patients were diagnosed as VN and completed MRI angiography. 12 patients had VA abnormalities (9.23%). 9/12 patients (75.0%) had same lesion side of VN and VA lesions (p=0.098). Hospitalization period, duration of dizziness and duration of spontaneous nystagmus between normal VA group and abnormal VA group had no significant difference. However, duration of spontaneous nystagmus considering only abnormal caloric test group was significantly lower in abnormal VA group than normal VA group (p=0.001). Conclusion: The present study suggested that VA disorder might have relationship with VN, as vascular factor is one of the most common reasons for VN. Moreover, spontaneous nystagmus recovers faster in patients with VA disorder.
