Definition
'Intraventricular' means 'within the ventricles' of the brain. These ventricles are interconnected cavities filled with cerebrospinal fluid (CSF). CSF cushions the brain and spinal cord, removing waste products. 'Intraventricular' refers to something located or occurring inside these cavities. Think of it like something happening inside the brain's swimming pools. Intraventricular hemorrhage is bleeding into these ventricles.
