intraventricular hemorrhage
Bleeding into the brain's ventricular system, most commonly seen in premature infants.
Full Definition
Intraventricular hemorrhage (IVH) is bleeding into the ventricular system of the brain, predominantly affecting premature infants under 32 weeks gestation. The hemorrhage typically originates from the fragile germinal matrix and is graded I-IV based on extent and presence of ventricular dilation. Risk factors include prematurity, birth asphyxia, and rapid changes in cerebral blood flow. Severe IVH can lead to post-hemorrhagic hydrocephalus, cerebral palsy, and developmental delays. Prevention strategies focus on gentle handling, maintaining cerebral perfusion pressure, and avoiding rapid volume or pressure changes.
Usage
Usage note: Always specify grade (I-IV) when known. IVH acceptable after first use.
