DIAGNOSTIC VALUE OF STRUCTURAL AND FUNCTIONAL CHANGES IN THE CAROTID AND VERTEBRAL ARTERIES IN ARTERIAL HYPERTENSION, ASSOCIATED WITH BENIGN PAROXYSMAL POSITIONAL VERTIGO
Objective of the study was to assess the diagnostic significance of hemodynamic disorders in the area of carotid and vertebral arteries in patients with hypertension combined with benign paroxysmal positional vertigo (DPPG) using ultrasound duplex scanning of neck vessels. Material and methods. Thirty eight patients of the clinic of Federal Research Center for Fundamental and Translational Medicine with hypertension and concomitant dizziness were examined. The state of carotid and vertebral arteries, blood flow in the arteries were assessed by duplex ultrasound scanning using the Vivid E9 apparatus. Results and discussion. The influence of the blood flow at the level of carotid and vertebral arteries on the severity of clinical symptoms of dizziness in patients with hypertension with concomitant DPPG was shown. The clinical significance of atherosclerotic changes in carotid arteries, tortuosity of carotid and vertebral arteries of the effectiveness of treatment and prevention of dizziness in patients with hypertension and DPPG was revealed. It is shown that in patients with hypertension and comorbid DPP, the severity of the relationship of hemodynamically significant changes in the carotid and vertebral arteries with clinical manifestations of dizziness is greater than in patients with hypertension without DPP. The use of ultrasound duplex scanning of brachiocephalic arteries in hypertension with comorbid vertigo allows for differential diagnosis of benign paroxysmal positional vertigo and cerebrovascular dyscirculatory disorders, the degree of their participation in clinical manifestations of dizziness. A new medical technology for the diagnosis of pathogenic mechanisms of dizziness in patients with hypertension, using ultrasound duplex scanning of carotid and vertebral arteries, allows to personalize treatment and prevention in such patients.
