“…After drainage procedure, RI-ACA values dropped down to the normal range because of increased values of Ved. Change of Doppler parameters before and after drainage procedure confirmed positive effect of the drainage procedure to cerebral circulation in children with hydrocephalus [319,320,387]. 3.…”

“…The values of PI-MCA correlated with intracranial pressure of children with shunt obstruction [431]. Increased resistance index of the cerebral arteries was also confirmed in children with dysfunction of drainage systems [319,320,432]. In addition to increased resistance index of the cerebral arteries, vascular reactivity malfunction to p a CO 2 change was detected in children with active hydrocephalus before drainage system insertion and in dysfunction of drainage system.…”

“…On the other hand, the values of RI-ACA increased in the shunt-dependent children with dysfunctional drainage system and ETV, even though the cerebral ventricles enlarged slightly or maintained the same size. After successful revision surgery, the value of RI-ACA dropped down to normal range [319,320,387]. To sum up, it can be said that including assessment of cerebral circulation by transcranial Doppler ultrasonography into management of children with hydrocephalus provides additional information to clinical manifestation and morphological results of imaging techniques.…”

“…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].…”

Elevated renal tissue oxygenation in premature fetal growth restricted neonates: An observational study

et al. 2018

View full text Add to dashboard Cite

BackgroundFetal growth restriction (FGR) is associated with an increased risk for kidney disease in later life. Studies reporting on early signs of renal disturbances in FGR are sparse and mostly include invasive measurements, which limit the possibility for early identification and prevention. We aim to investigate whether renal tissue oxygen saturation (rSO2) measured with near-infrared spectroscopy (NIRS) and the derived value fractional tissue oxygen extraction (FTOE) differ between premature FGR and control neonates in the first three days after birth.MethodsNine FGR and seven control neonates born <32 weeks of gestation were included. FGR was defined as biometry

Assessment of renal circulation in small for gestational age and appropriate for gestational age term newborns: A prospective study

Abstract: Based on our findings, we suggest that renal circulation is not negatively influenced by intrauterine growth restriction in SGA neonates compared with AGA newborns.
