However, more severe IVH can result in hydrocephalus, a potentially fatal condition in which too much fluid collects in the ventricles, exerting increased pressure on the brain and causing the baby's head to expand abnormally.
Many children with congenital brain anomalies, such as Chiari I malformation and nearly 50 percent of those affected by hydrocephalus, have normal intellectual functioning, and some have unimpaired physical mobility.
Children with a hemorrhagic stroke may be transferred to a center with neurosurgical facilities so the proper treatment, such as decompression or hydrocephalus drainage, can be provided by skilled specialists.
Approximately 80-90 percent of children with Chiari malformation Type II also have hydrocephalus, a condition in which one or more of the ventricles becomes enlarged due to an accumulation of CSF.
Dandy-Walker malformation: Symptoms of hydrocephalus, lack of muscle tone or floppiness, seizures, spasticity, deafness, irritability, visual impairment, deterioration of consciousness, paralysis.
Some severely mentally impaired children who also have hydrocephalus or Williams syndrome may acquire exceptional conversational language skills, sometimes called the "chatterbox syndrome."
People who experience seizures, for example, may be given anticonvulsant drugs, and people who develop fluid on the brain (hydrocephalus) may have a shunt inserted to drain the fluid.
Malformations associated with hydrocephalus (Dandy-Walker, Chiari II, and some cases of hydranencephaly) may be treated by installation of a drainage shunt for cerebrospinal fluid.
However, babies who survive the surgery appear to be 33 to 50 percent less likely to have hydrocephalus, a condition that requires surgically implanted tubes or shunts to remove fluid from the ventricles (cavities of the brain).
Where the dropsical condition is more or less general the term " anasarca " is applied to it; if the tissues are infiltrated locally the term " oedema " is employed; and various names are applied, with a local significance, to dropsies of individual parts or cavities, such as " hydrothorax," " hydroperitoneum " or " ascites," " hydrocephalus," and so on.
