OBJECTIVE: This study aimed to investigated the prevalence of abnormality from vertebrobasiler system in Vertigo BACKGROUND: Vertigo is a sensation that someone felt rotates to the surrounding environment. Vertigo can be caused by impairment of labyrinth organ, the 8th cranial nerve lesion or disturbance of brainstem and cerebellum due to interference of the vertebrobasiler system circulation. Objective of this study is to know the prevalence of vertebrobasiler circulation system abnormality that evaluated using head CT (computed tomography) angiography in both of central and peripheral type of vertigo. DESIGN/METHODS: It was a cross-sectional study that done in one year. Patients that complained of vertigo were recruited from 2 private hospitals in Jakarta, Indonesia. Assessment of vertigo was made by a neurologist. Head CT angiography was performed in all subjects and evaluated by an interventional neurologist. RESULTS: There were 40 subjects that complained of vertigo, age range 39 years up to 68 years old, consisted of 35 (87.5%) females and 5 (12.5%) males. Twenty-six subjects (65%) had central type of vertigo whereas 14 subjects (35%) had peripheral type. Head CT angiography revealed abnormality of vertebrobasiler circulation system in 24 subjects (60%) which were vertebrobasiler junction stenosis in 3 subjects, stenosis of either one or both sides of vertebral artery in 9 subjects, stenosis of basilar artery in 7 subjects, stenosis at ostium of vertebral artery in 2 subjects, and hypoplasia of vertebral artery in 3 subjects. Eighteen subjects of central type of vertigo group showed abnormality result in head CT angiography while 6 subjects of peripheral type of vertigo group did. CONCLUSIONS/RELEVANCE: Abnormality of vertebrobasiler circulation system often occurs in people with vertigo; either central or peripheral type. In future, this study will be continued with a larger sample and using of cerebral DSA (digital subtracted angiography) as a diagnostic procedure to evaluate cerebral circulation system.
