Diagnostic features of vertebrobasilar insufficiency with signs of a tortuous V1 segment of the vertebral artery

Abstract

Of the total number of circulatory disorders in the vertebrobasilar basin (VBB), which reaches 30 % of all diagnosed disorders of cerebral circulation, transient forms acquire the character of stable in 25–30 % and progress to the stage of complete stroke in 25–50 out of 100 patients within 2–5 years of the disease. The level of disability at the same time reaches 80 %. To date, there are no recommendations and developments for the management of patients with combined lesions of the extracranial arteries occurring against the background of the syndrome. The known methods of diagnosis of VSN are based on the assessment of clinical and hemodynamic, structural and morphological features and the results of dynamic observation. These methods allow using expensive equipment and repeated long-term examinations to objectify the condition of HA, and with the help of rotational samples to determine the probable genesis of VSN. However, the disadvantage is the low level of availability to attract expensive equipment and a dichotomically qualitative approach to the diagnostic process. Therefore, a diagnostic algorithm was developed, on the basis of which it is possible not only to determine the indications for reconstructive operations on V1 PA arteries with the VDN clinic, but also to predict the clinical effectiveness of the operation, but also to predict the effectiveness of surgical treatment.
