What is the infection rate for ventriculosubgaleal shunts after an intraventricular hemorrhage?
Ventriculosubgaleal shunts (VSGS) are temporary drains used in premature infants with posthemorrhagic hydrocephalus (PHH) after intraventricular hemorrhage (IVH). They divert excess cerebrospinal fluid into a pocket under the scalp to reduce infection risk compared to other temporary methods. The infection rate is a key safety measure. A recent meta-analysis reports a pooled infection rate of 9%, while older studies show rates around 14%.
What the research says
A 2024 systematic review and meta-analysis of 19 studies including 562 neonates found a pooled VSGS-related infection rate of 9% (95% CI: 5% to 12%) 3. This is the most comprehensive estimate available. An older multicenter study from 2009 reported a higher infection rate of 14% (5 of 36 patients) during temporary VSGS use 7. The difference may reflect improvements in technique or patient selection over time. For comparison, other temporary methods like ventricular reservoirs had similar infection rates (13%) in the same older study 7, and antibiotic-impregnated external ventricular drains showed a 7.7% infection rate in a small 2022 study 8. Overall, VSGS infection rates are relatively low and comparable to other temporary CSF diversion methods.
What to ask your doctor
- What is the infection rate for ventriculosubgaleal shunts at this hospital?
- How does the infection risk of VSGS compare to other temporary drainage options for my baby?
- What signs of infection should I watch for after VSGS placement?
- How long is the VSGS typically left in place, and does longer duration increase infection risk?
- What steps are taken to prevent infection during and after VSGS surgery?
