“…The results of the study [319] targeted at children with hydrocephalus confirmed that asymmetric dilatation of cerebral ventricles had significantly influenced values of basal RI-ACA before drainage procedure and compressive RI-ACA after it. Statistical analysis showed that values of basal RI-ACA after drainage procedure and compressive RI-ACA before drainage procedure was not influenced by asymmetric dilatation of cerebral ventricles.…”

“…Therefore, the authors of the study assume that Doppler parameters of the cerebral arteries are influenced by combination of increased intracranial pressure and dilatation of cerebral ventricles. Additionally, the results of the study confirmed that not only progressive but also stable dilatation of cerebral ventricles with increased intracranial pressure has a negative effect on cerebral circulation [319]. On the contrary, in neonates with stable dilatation of cerebral ventricles, in which drainage procedure was not necessary, basal Doppler parameters of blood flow in ACA reached normal values [400].…”

“…After drainage procedure, the clinical signs of intracranial hypertension had disappeared in the early postsurgical period. However, in 22.5% of cases, stable dilatation of the cerebral ventricles had been present after the surgery [319]. Also, other studies on pediatric hydrocephalus [28,320,321] confirmed decrease of size of the cerebral ventricles due to cerebrospinal fluid derivation when it was assessed by ultrasonography.…”

“…The results of studies showed that increased cerebrovascular resistance before drainage procedure was determined by increased intracranial pressure, which is reversible after drainage procedure. Positive impact of drainage procedure on Doppler parameters of the cerebral arteries is based on postsurgical change of cerebrovascular resistance and regulation of cerebral circulation due to decrease of intracranial pressure [319,320,384,[387][388][389][390].…”

“…month and 18 years, and these studies occurred in settings outside the pediatric intensive care unit (PICU) [1][2][3][4][5][6][7]. Thus, the main issue with either technique is that there are few data in the PICU population, and the clinical meaning of transcranial Doppler findings in this population remains unclear.…”
