Germinal Matrix-Intraventricular Hemorrhage Gradings WebBleeding occurs initially in the immediate periventricular areas causing a "periventricular" hemorrhage or "PVH." If the bleeding persists, the expanding volume of blood dissects into the adjacent lateral ventricles leading to an "intraventricular" hemorrhage or "IVH."
