Posthemorrhagic hydrocephalus in the preterm infant
Insights
Delayed onset posthemorrhagic hydrocephalus in low birth weight infants has a poor long-term outlook. Medical therapy alone may arrest hydrocephalus in some cases, but shunt placement is often required.
Area of Science:
- Neonatal Neurology
- Pediatric Neurosurgery
- Developmental Pediatrics
Background:
- Delayed onset posthemorrhagic hydrocephalus is a serious complication in low birth weight infants following intracranial bleeding.
- Clinical signs of hydrocephalus typically manifest after two weeks of age in affected infants.
Purpose of the Study:
- To evaluate the long-term outcomes of low birth weight infants treated for delayed onset posthemorrhagic hydrocephalus.
- To compare the efficacy of surgical shunt placement versus medical management (lumbar puncture and diuretics) for this condition.
Main Methods:
- Retrospective analysis of 22 low birth weight infants treated between 1969 and 1978.
- Group 1 (n=12): Treated with surgical shunt placement before August 1974.
- Group 2 (n=10): Received medical therapy (lumbar puncture, diuretics) before shunt placement after September 1974.
Main Results:
- Seven of ten infants in Group 2 had hydrocephalus arrested with medical therapy alone.
- Long-term follow-up (1-8 years) in 18 infants showed poor intellectual outcomes.
- Only 2/12 shunt-treated and 3/6 medically-treated infants achieved an IQ score of 85 or greater.
Conclusions:
- Low birth weight infants developing clinically overt hydrocephalus after intracranial bleeding face a poor long-term prognosis.
- While medical management can be successful in some cases, overall developmental outcomes remain a significant concern.
- Further research is needed to improve management strategies and long-term neurodevelopmental outcomes for this vulnerable population.
Abstract:
Between 1969 and 1978 we treated 22 low birth weight infants for delayed onset posthemorrhagic hydrocephalus. All developed clinical signs of hydrocephalus after 2 weeks of age. The diagnosis was determined in 12 infants before August 1974, and they were treated by surgical placement of a shunt. In the ten infants born after September 1974, an attempt was first made to control the hydrocephalus with repeated lumbar puncture and diuretics prior to placing a shunt. In seven of the ten the hydrocephalus was successfully arrested by medical therapy alone. Follow-up assessments at 1 to 8 years of age were done on 18 infants. Two of the 12 treated by permanent shunts and three of six treated medically had an IQ score of 85 or greater. These results indicate a poor long-term outlook for the low birth weight infant who develops clinically overt hydrocephalus after intracranial bleeding.
