The investigation of cerebral hemodynamics in 318 pilots with the use of ultrasonic dopplerography and transcranial dopplerography has shown that the earliest and most frequent manifestations of cerebrovascular disorders are observed in the vertebrobasilar zone (VBZ). The significant indices characterizing the morphofunctional condition of cerebral arteries are the results of triplex scanning of the main vessels. The pathologic changes in VBZ arteries, the variants of abnormal disposition of vertebral arteries, the secondary changes connected with extravasal effect are often detected during the early cerebrovascular disorders. According to the results of cervical vertebra roentgenography the degenerative-and-dystrophic changes, the congenital anomaly and traumatic injuries could play a certain role in the development of early cerebrovascular disorders in VBZ. Most frequently the symptoms of vertebrobasilar vascular insufficiency develop due to the cervical vertebral dislocation, uncovertebral arthrosis, Kimmerle's anomaly and other changes. |
