The cause of recurrent vertigo is vascular compression of the vestibular cochlear nerve (VC PUN) often. The pathogenesis of recurrent vertigo caused by VC PUN in the adult population did not specified.The aim: to assess the condition of the brachiocephalic vessels in patients with vertigo caused by vascular compression of the vestibular nerve.Materials and methods: We examined 80 patients with recurrent vertigo caused by VC VN according to neuroimaging, average age (43,09±13,47 years) and 71 healthy subjects, average age (45,85 ± 12,98 years). There were performed clinical and neurological examination, magnetic resonance imaging of the brain, ultrasound duplex scanning of the carotid and vertebral arteries, vestibulometry. We compared the diameter of the right and left, as well as the peak systolic blood flow rate (Vps) for the extracranial segments of the right and left vertebral artery (VA), the intima-media complex (IMC), the presence of extravasal compression, stenotic (>20,0%) and non-stenotic (<20,0%) atherosclerotic lesions of the brachiocephalic arteries.Results: In patients with VC VN (on MRI) and signs of latent vestibular dysfunction (VD) in the interictal period is significantly dominated by the tortuosity of VA (χ2 =22,16, p 40 cm/s probability of identification due to VC VN is 73,1%, the Vps VA left >44 cm/s the probability of detecting VD is 75,0%, indicating high diagnostic value of this indicator in the differential diagnosis of VD, due to the VC VN.
