Insights

Ventriculoperitoneal (VP) shunt insertion, particularly occipital shunts, significantly increases the risk of contralateral positional plagiocephaly in infants. Careful monitoring and head positioning advice are recommended post-surgery.

Area of Science:

  • Pediatric Neurosurgery
  • Craniofacial Development
  • Neurology

Background:

  • Positional plagiocephaly is a common condition in infants.
  • Ventriculoperitoneal (VP) shunts are frequently used to treat hydrocephalus in children.
  • The relationship between VP shunt placement and plagiocephaly requires further investigation.

Purpose of the Study:

  • To test the hypothesis that ventriculoperitoneal (VP) shunt insertion increases contralateral positional plagiocephaly.
  • To identify risk factors associated with VP shunt placement and positional plagiocephaly.

Main Methods:

  • Retrospective review of 339 children undergoing VP shunt insertion.
  • Assessment of positional plagiocephaly using the cranial vault asymmetry index.
  • Multinomial logistic regression to analyze relationships between plagiocephaly, shunt position, gender, and age.

Main Results:

  • Occipital VP shunts are significantly associated with an increased risk of contralateral positional plagiocephaly.
  • This risk is particularly pronounced within the first 12 months of life.

Conclusions:

  • Post-operative head positioning advice and careful follow-up are crucial for infants with VP shunts.
  • Consideration of active monitoring, physiotherapy, and health visitor interventions may help prevent plagiocephaly.
  • Alternative surgical approaches like endoscopic third ventriculostomy or anterior shunt placement may be beneficial in select cases.
