Posthemorrhagic hydrocephalus is defined as progressive ventricular dilatation after an IVH, either acute (caused by either a blood clot that impairs the normal flow of cerebral spinal fluid [CSF], or obstruction to the absorption of CSF at the level of the arachnoid villi), or chronic (due to obliterative arachnoiditis or blockage from necrotic debris, reactive gliosis, or disrupted ependyma that interferes with flow of the CSF).
