Diagnosis & Imaging
Ventricular index
The ventricular index is a measurement of ventricle size, including forms used in premature infants on ultrasound.
In short: Ventricular index
- It measures ventricle width, often on ultrasound in infants.
- It is used to monitor ventricular enlargement in premature babies.
- Specific reference charts exist for premature infants.
- It helps guide decisions about intervention.
What it is
The ventricular index is a measurement of ventricle width, used to assess ventricular enlargement. A widely used form, measured on cranial ultrasound in premature infants, compares ventricle width to reference values for the baby's age.
Understanding Ventricular index
In premature infants at risk for post-hemorrhagic ventricular dilation, the ventricular index is measured on serial cranial ultrasounds and plotted against reference charts (such as age-specific percentile charts). This allows the team to monitor whether the ventricles are enlarging and by how much, which helps guide decisions about whether and when to intervene (for example, with temporizing measures or a shunt). The ventricular index is one of the standardized measurements used to track ventricle size, particularly valuable in the close monitoring of premature babies. As with other indices, the trend over time is key.
Why it matters
Understanding the ventricular index helps families see how ventricle size is measured and tracked in premature infants, and how these measurements help guide decisions about intervention for developing hydrocephalus.
Common questions
