[Posthemorrhagic hydrocephalus in the preterm infant: current evidence in diagnosis and treatment]
Insights
Intraventricular haemorrhage and posthemorrhagic hydrocephalus are serious neurological issues in preterm infants. This review summarizes key diagnostic and therapeutic evidence for managing these complications in neonates.
Area of Science:
- Neonatal Neurology
- Pediatric Neurosurgery
Context:
- Intraventricular haemorrhage (IVH) and posthemorrhagic hydrocephalus (PHH) are significant neurological complications in preterm infants.
- Increasing incidence due to preterm births and improved survival rates necessitates updated clinical understanding.
- Existing evidence is often fragmented, highlighting a need for consolidated information.
Purpose:
- To summarize current diagnostic and therapeutic evidence for preterm-related PHH.
- To provide a foundation for developing clinical guidelines for managing periventricular hemorrhage complications.
Summary:
- This review consolidates essential clinical evidence on diagnosing and treating posthemorrhagic hydrocephalus in preterm infants.
- Recommendations were developed by a working group in Pediatric Neurosurgery of the Spanish Society of Neurosurgery.
Impact:
- Aims to improve the management of neurological complications in preterm neonates.
- Serves as a foundational step towards establishing standardized clinical practice guidelines.
Abstract:
Intraventricular haemorrhage and posthemorrhagic hydrocephalus are the most important neurological complications in preterm infants during the neonatal period. The prevalence of germinal matrix intraventricular haemorrhage widely varies depending on the population of study, but it is in any case increasing due both to the higher incidence of multiple and preterm deliveries as well as the longer survival of preterm infants favoured by recent advances in perinatal care. It is therefore of the utmost convenience to be familiar with the most important clinical evidence regarding this entity. However, the available evidence is often incomplete and piecemeal. The objective of the present review is to summarise the main diagnostic and therapeutic points regarding preterm related posthemorrhagic hydrocephalus. The participants of the working-group in Pediatric Neurosurgery of the Spanish Society of Neurosurgery were asked to write these recommendations down. This hopefully represents the first step towards the definition of a clinical guide in the treatment of complications related to periventricular hemorrhage of the preterm infants.
