Materials and methods: The study involved 249 male patients, aged from 21 to 60 years who worked as locomotive drivers. We used Doppler examination and studied Doppler Indexes of cerebral vessels. Results: Results of examination showed that with increasing length of work of workers of locomotive crews (together with increasing of their age) we have established: 1) Reduction the elasticity of blood vessels (77.6% of the patients); 2) Increased violation of venous circulation (86.4%); 3) Reduced blood flow in the basilar artery (64%); 4) Reduced blood flow in the right and left vertebral arteries (65.6% and 65.5% respectively); 5) Increase in the thickness of intimate / media complex more than 1.1 in 62 % of drivers. All of that also connected with length of their work. Conclusions: we founded that speed of blood flow and elasticity in intra- and extra cranial vessels reduced with increase the length of service of workers of locomotive crews. Also we received such results: increasing violation of venous circulation, reducing blood flow in the basilar artery and reducing of blood flow in right and left vertebral arteries, increase intima / media thicknesses greater than 1,1 in locomotive drivers. popup.nrat_date 2026-04-22 Close
