An intraventricular hemorrhage (or "IVH") is a bleeding of the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhaging in stroke.

In infants

This type of hemorrhage is particularly common in infants, especially premature infants or those of very low birth weight.Annibale DJ and Hill J. 2006. [http://www.emedicine.com/ped/topic2595.htm Periventricular Hemorrhage-Intraventricular Hemorrhage] . Emedicine.com. Retrieved on June 19, 2007.] The cause of IVH in premature infants, unlike that in older infants, children or adults, is rarely due to trauma. Instead it is thought to result from changes in perfusion of the delicate cellular structures that are present in the growing brain. The lack of blood flow results in cell death and subsequent breakdown of the blood vessel walls, leading to bleeding. While this bleeding can result in further injury, it is itself a marker for injury that has already occurred. Most intraventricular hemorrhages occur in the first 72 hours after birth.

In adults

Intraventricular hemorrhage is rare in adultsMayfrank L, Kissler J, Raoofi R, Delsing P, Weis J, Kuker W, and Gilsbach JM. 1997. [http://stroke.ahajournals.org/cgi/content/full/28/1/141 Ventricular Dilatation in Experimental Intraventricular Hemorrhage in Pigs: Characterization of Cerebrospinal Fluid Dynamics and the Effects of Fibrinolytic Treatment] . "Stroke", 28:141–148. Retrieved on June 19, 2007.] and requires a great deal of force to cause. Thus the hemorrhage usually does not occur without extensive associated damage, and so the outcome is rarely good.Dawodu S. 2007.

Prognosis is also dismal when IVH results from intracerebral hemorrhage related to high blood pressure and is even worse when hydrocephalus follows. It can result in dangerous increases in intracranial pressure and can cause potentially fatal brain herniation.

Associated conditions

Brain contusions and subarachnoid hemorrhages are commonly associated with IVH.LeRoux PD, Haglund MM, Newell DW, Grady MS, and Winn HR. 1992. [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=1407453&dopt=Abstract "Intraventricular hemorrhage in blunt head trauma: an analysis of 43 cases."] "Neurosurgery". Volume 4, pp. 678-84. PMID 1407453. Retrieved on June 19, 2007.] The bleeding can involve the middle communicating artery or the posterior communicating artery.

In both adults and infants, IVH can cause dangerous increases in intracranial pressure, damage to the brain tissue, and hydrocephalus.
