Is a ventriculosubgaleal shunt safe for premature babies with posthemorrhagic hydrocephalus?
A ventriculosubgaleal shunt (VSGS) is a type of medical device used to drain excess cerebrospinal fluid (CSF) in infants. It is often used as a temporary measure for premature babies who develop posthemorrhagic hydrocephalus, which occurs after an intraventricular hemorrhage (IVH).
What the research says
Research indicates that VSGS is a safe and effective treatment for neonatal posthemorrhagic hydrocephalus (PHH) 35. This type of shunt uses the subgaleal space to drain fluid, which helps manage the condition while reducing the risk of infection compared to other methods 36. It allows doctors to control hydrocephalus until a baby reaches an appropriate weight and the cerebrospinal fluid becomes clear enough for a permanent ventriculoperitoneal (VP) shunt 36.
A systematic review and meta-analysis of 19 studies involving 562 neonates found that the risk of complications with VSGS is low. The study reported a 9% infection rate, a 4% need for revision, a 2% catheter obstruction rate, and a 1% migration rate 36. Other clinical reports also describe VSG as an effective way to manage hydrocephalus while minimizing risks like CSF leaks or infections 7. In some cases, the use of a VSGS may even allow a baby to avoid needing a permanent shunt altogether 57.
What to ask your doctor
- What are the specific benefits of using a ventriculosubgaleal shunt for my baby's condition?
- What is the expected timeline for transitioning from a temporary shunt to a permanent one?
- What are the risks of infection or catheter migration with this type of shunt?
- How does a ventriculosubgaleal shunt compare to other types of drainage for premature infants?
