Intraventricular hemorrhage

Intraventricular hemorrhage (IVH) is bleeding inside or around the ventricles—spaces in the brain that contain the protective cerebral spinal fluid.

• IVH is most common in premature babies, especially babies weighing less than three pounds, five ounces.
• Nearly all IVH occurs within the first three days of life.
• It's not clear why IVH occurs.
