Does the neurologic prognosis correlate with the different IVHs?
Generally, grades I and II IVH are relatively benign with some studies showing no long-term adverse developmental consequences.
Grade III and periventricular hemorrhagic infarction (formerly grade IV) are consistently associated with adverse outcomes, with grade IV having by far the greatest likelihood of severe neurologic sequelae such as spastic quadriparesis, blindness, and cognitive impairment.
Unilateral hemorrhages are associated with better neurodevelopmental outcomes than bilateral hemorrhages.
