Plasma Ultrafiltrate

Cerebrospinal fluid (CSF) is largely (70-80%) produced by the choroids plexus of the ventricles and is considered as the plasma ultrafiltrate. While CSF formation, circulation, and composition appear to be physiological and physical, its absorption appears to be mainly physical. The formation, composition, circulation, absorption, and changes in pathological conditions of CSF are discussed briefly in this review article. The CSF pressure dynamics studies provide information about the tightness, elastance, or outflow resistance of the CSF in the CNS. We believe that the present study shall help to provide essential details of CSF physiology which are important to many disciplines including radiology, neurology, and neurosurgery.

Background ― Posthemorrhagic hydrocephalus in newborns with occlusion of cerebrospinal fluid leads to decompensation of cerebrospinal fluid dynamics. There is no single method that meets all the criteria for the effectiveness and safety of treatment. The study goal was to investigate the use of coronary translambdoid subarachnoid ventriculostomy (CTSV) and ventricular subarachnoid stenting (VSS) in the treatment of neonatal hydrocephalus. Material and Methods ― The analysis of the posthemorrhagic hydrocephalus treatment in 327 newborns for the period of 2000-2018 in Crimea. Two groups have been identified. In the Group 1, 184 children underwent standard treatment according to the ‘LVV protocol’ with lumbar and ventricular punctures with 20-22G needles, while with progression of hydrocephalus, with ventriculosubgaleal drainage and ventriculoperitoneal shunt. In 143 children with occlusion and ventricular block, the treatment complex included CTSV – RF Patent No. 2715535, and ventricular drainage by the ventricular subarachnoid stenting (VSS) – RF Patent No. 2721455. Results ― An increase in the treatment radicality under CTSV is achieved through the use of the cerebral needles of a larger diameter (14G) and puncture access zones, elimination of occlusion, while under VSS, restoration of intracranial circulation and absorption of cerebrospinal fluid is ensured by prolonged sanitation with a saline solution of cerebrospinal fluid spaces. A positive outcome with compensation for hydrocephalus was achieved in 75.4% of cases versus 28.2% under the conventional protocol (p<0.001). In other cases, the imbalance of production and absorption of cerebrospinal fluid remained, which required the integration of the VSS with the peritoneal segment of the shunt, without further replacement and reinstallation of the system. Conclusion ― Our results allow us to consider the effectiveness of CTSV and VSS inclusion in the contemporary algorithm for the treatment of decompensated posthemorrhagic hydrocephalus in newborns.
