Insights

Infective causes, including TORCH infections and meningitis, are a significant factor in childhood hydrocephalus. Post-infective hydrocephalus often leads to developmental delays and necessitates frequent shunt revisions.

Area of Science:

  • Pediatric Neurosurgery
  • Neurology
  • Infectious Diseases

Background:

  • Hydrocephalus affects children worldwide, with varying etiologies and outcomes compared to Western populations.
  • Understanding the specific causes and complications in a local context is crucial for effective management.

Purpose of the Study:

  • To analyze the etiology, clinical features, complications, and outcomes of hydrocephalus in 50 children.
  • To determine the incidence of shunt revisions and compare findings with Western counterparts.

Main Methods:

  • Retrospective analysis of 50 hydrocephalic children with a minimum 6-month follow-up.
  • Data collected from discharge summaries, including clinical features, imaging, treatment, and shunt revision records.

Main Results:

  • The most common etiologies were aqueductal stenosis (36%) and post-infective hydrocephalus (36%), including post-tubercular and bacterial meningitis, and TORCH infections.
  • Fifteen children (30%) required shunt revision due to infection (16%) or obstruction (14%).
  • Intra-fourth ventricular neurocysticercus cysts were identified as a rare cause of CSF pathway obstruction.

Conclusions:

  • Infective etiology is a major contributor to hydrocephalus in this cohort, emphasizing the need to consider TORCH infections.
  • Post-infective hydrocephalus is linked to developmental delays and mental retardation.
  • A high incidence of shunt revisions was observed, particularly with medium-pressure shunts, highlighting potential challenges in long-term management.
