haemorrhage have severe cerebral palsy. An estimated 15% of preterm infants who survive develop cerebral palsy and 27% of the infants who survive experience moderate to severe neurosensory deficits by the time they reach 18–24 months old. Prognosis is very poor 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 ICP and can cause potentially fatal brain herniation. Even independently, IVH can cause morbidity and mortality. First, intraventricular blood can lead to a clot in the CSF conduits blocking its flow and leading to obstructive hydrocephalus which may quickly result in increased intracranial pressure and death. Second, the breakdown products from the blood clot may generate an inflammatory response that damages the arachnoid granulations, inhibiting the regular reabsorption of CSF and resulting in permanent communicating hydrocephalus. Associated conditions Brain contusions and subarachnoid hemorrhages are commonly associated with IVH. The bleeding can involve the anterior communicating artery or the posterior communicating artery. In both adults and infants, IVH can cause dangerous increases in ICP, damage to the brain tissue, and hydrocephalus. Epidemiology IVH has been reported to occur in approximately 25% of infants who are born with a very low birth weight. In preterm infants, intraventricular haemorrhage and germinal matrix haemorrhage are the most widely reported neurological disorders. Approximately 12,000 infants each year are diagnosed with germinal matrix haemorrhage or intraventricular haemorrhage in the United States. Research In 2002, a Dutch retrospective study analysed cases where neonatologists had intervened and drained CSF by lumbar or ventricular punctures if ventricular width (as shown on ultrasound) exceeded the 97th centile as opposed to the 97th centile plus 4 mm. Professors Whitelaw's original Cochrane review published in 2001 as well as evidence from previous randomised control trials indicated that interventions should be based on clinical signs and symptoms of ventricular dilatation. An international trial has instead looked an early (97th centile) versus late (97th centile plus 4 mm) for intervening and draining CSF. DRIFT has been tested in an international randomised clinical trial; although it did not significantly lower the need for shunt surgery, severe cognitive disability at two years Bayley (MDI <55) was significantly reduced. Repeated lumbar punctures are used widely to reduce the effects in increased intracranial pressure and an alternative to ventriculoperitoneal (VP) shunt surgery that cannot be performed in case of intraventricular haemorrhage.
