Abstract
Forty newborns with hydrocephalus were evaluated before and after the drainage procedure The morphological parameters of brain ventricular index width of ventricles haemorrhagic lesions asymmetric ventricular dilatation and dynamics of ventricles were measured by transcranial ultrasonography The haemodynamic parameters of ACA peak systolic blood flow velocity enddiastolic blood flow velocity and resistance index/RI/ were evaluated by Doppler ultrasonography The correlation between morphological and haemodynamic parameters was analysedWe found significant decrease of ventricular dilatation which was accompanied with significant decrease of basal and compressive RIACA after drainage procedure The correlation between basal RIACA compressive RIACA and the dynamics of ventricular dilatation was not significant before and after drainage operation as well The significant correlation between preoperative basal RIACA postoperative compressive RIACA and asymmetry of cerebral ventricles was confirmed Statistical analysis showed significant correlation between basal RIACA compressive RIACA and haemorrhagic lesions after drainage operationThe results of our study showed the alteration of Doppler parameters of cerebral circulation in newborns with hydrocephalus before the drainage procedure The successful drainage operation leads to the improvement of haemodynamic parameters of cerebral circulation However the statistical analysis showed the influence of some intracranial factors—the asymmetry of dilatation of lateral cerebral ventricles and periventricular haemorrhagic lesions on the Doppler parameters of cerebral circulation
