This article includes discussion of neonatal intraventricular hemorrhage and post-hemorrhagic hydrocephalus. The foregoing terms may include synonyms, similar disorders, variations in usage, and abbreviations.


In this article, the authors review intraventricular hemorrhage in the neonate with respect to its clinical setting, cause, course, and management. Although the occurrence rate of INTRAVENTRICULAR HEMORRHAGE is lessening, the incidence is maintained due to improved survival of very low birth weight infants. Therefore, our continued understanding of the condition is still important for the clinician.

Key points


• Intraventricular hemorrhage originates in the germinal matrix of the infant born at less than 34 weeks gestation.


• Intraventricular hemorrhage results from brain blood flow perturbations brought on by defective cerebral autoregulation in association with the medical problems of prematurity.


• Management of intraventricular hemorrhage consists of monitoring for ventricular dilation and drainage of cerebrospinal fluid (CSF) by one of several possible methods.


• Neurologic sequelae are significant and related to the severity of the hemorrhage.
