Blood flow in cerebral vessels and main vessels of the neck in newborns from healthy mothers: exploring the parameters

Objective. To analyse of blood flow in the cerebral and main vessels of the neck in newborns whose mothers had no complications during pregnancy using Doppler ultrasound.

Materials and methods. 123 newborns were examined. The parameters included gender distribution, anthropometry, and health. Ultrasound examination included neurosonography with dopplerography of brain vessels and examination of the main vessels of the neck using microconvex and linear sensors.

Results. Neurosonography did not reveal any brain pathologies. Dopplerometry of cerebral vessels: in the anterior cerebral artery, the resistance index is 0.62±0.07, the pulsation index is 1.08±0.17; in the middle cerebral artery, the resistance index is 0.66 ± 0.09, the pulsation index is 1.14 ± 0.32. Ultrasound examination of the main vessels of the neck: in the common carotid artery, the resistance index is 0.64 ± 0.05 (left) and 0.66 ± 0.04 (right), the pulsation index is 1.34 ± 0.16 (left) and 1.37 ± 0.13 (right); in the internal carotid artery, the resistance index is 0.54 ± 0.04 (left) and 0.56 ± 0.05 (right), the pulsation index is 1.19 ± 0.11 (left) and 1.21 ± 0.12 (right); in the external carotid artery, the resistance index is 0.74 ± 0.04 (left) and 0.76 ± 0.05 (right), the pulsation index is 1.39 ± 0.09 (left) and 1.41 ± 0.12 (right). The values indicate good vascular elasticity and low resistance to blood flow; the differences between the left and right sides of the vessels are explained by anatomy and are insignificant.

Conclusion. The study emphasizes the importance of timely diagnosis of disorders and monitoring of the state of blood supply to the central nervous system in the neonatal period. The data can serve as a reference for further research and development of standards for the diagnosis and treatment of pathologies associated with impaired cerebral hemodynamics.
