Anatomical patterns in the asymmetry of the diameter of the vertebral arteries according to the results of magnetic resonance imaging

Individual anatomical and functional features of the structure of the main arteries are important in identifying the causes of blood supply disorders in the vertebrobasilar basin, and the successful solution of clinical problems is based on the choice of optimal treatment and personalized prevention methods. Materials and methods. The data were provided by 305 volunteers. The material was collected on an MRI machine with a magnetic field strength of 1.5 T and the possibility of three-dimensional visualization of anatomical structures. The processing of the research results was carried out using the Evorad RIS-PACK Workstation 2.1 program and the Microsoft Excel 2007 application. Results and discussion. In most cases, the smaller diameter of the vessels on the right was determined, accounting for 68 % of all observations. When a smaller diameter of the vertebral artery was detected on the right, the difference between men and women in the absence of signs of concomitant changes in the spinal column was 7 %. Up to 33 % of cases were accompanied by moderate changes, and the number of significantly pronounced manifestations reached 20–25 %, diagnosed mainly among men. The non-linear nature of the move was 21–24 %. Conclusions. These features are related to the assessment of the anatomical variability of the vertebral arteries and allow for a more detailed clinical assessment of the reserve capabilities of the vessels of the vertebrobasilar basin.
