Abstract
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.
