Intraventricular haemorrhage and posthaemorrhagic ventricular dilatation: moving beyond CSF diversion

Area of Science:

• Neonatal neurosurgery
• Pediatric neurology
• Developmental neuroscience

Background:

• Advances in neonatal care increase survival rates for premature infants.
• Germinal matrix haemorrhage (GMH), intraventricular haemorrhage (IVH), and posthaemorrhagic ventricular dilatation (PHVD) significantly impact long-term cognitive and developmental outcomes in these infants.

Purpose of the Study:

• To review current neurosurgical management strategies for IVH and PHVD in premature infants.
• To discuss the importance of early PHVD diagnosis and intervention thresholds.
• To explore evolving treatment paradigms for intraventricular blood and its byproducts.

Main Methods:

• Review of current neurosurgical interventions for IVH and PHVD.
• Discussion of temporizing measures and definitive cerebrospinal fluid (CSF) diversion techniques.
• Evaluation of evidence for techniques like drainage, irrigation, fibrinolytic therapy (DRIFT), and neuroendoscopic lavage.

Main Results:

• Early diagnosis and intervention for PHVD are crucial.
• Various management options exist, including temporizing measures and CSF diversion.
• Emerging therapies aim to manage intraventricular blood and optimize infant outcomes.

Conclusions:

• Neurosurgical management of IVH and PHVD is critical for improving cognitive and developmental outcomes in premature infants.
• Optimizing treatment strategies for intraventricular blood can enhance neurodevelopmental and quality of life outcomes.
• Evidence-based review of techniques like DRIFT and neuroendoscopic lavage informs current practice.
