Specific features of cerebral hemodynamics in children under school age with natal injury consequences depending on the presence and level of cervical spine involvement

The children who suffer from the subclinical natal injuries of the cervical spine develop delayed complications that are caused by cerebro-vascular disorders and vertebrogenic changes. The instability of the cervical spine in some children results in the development of ischemia of the cerebral structures while in other children the cervical trauma itself leads to regional hemodynamic disorders. In children, even small amounts of stretching or compression of the vertebral artery is sufficient for cerebral circulation disorders to occur. Besides, due to rich sympathetic innervation of these arteries, the spasm of the whole arterial bed in the vertebrobasilar pool takes place. Clinically, these consequences manifest themselves in cervical insufficiency or myatonic syndrome. Cerebral hemodynamics in children with natal injuries of the cervical spine has its own specific features which have not been studied properly, and therefore deserve special attention as they contribute to diagnosing the disease and provide for early adequate therapy in the period when the disease clinical signs are minimal.
