Abstract

AIM:

To determine the prevalence, aetiology and clinical outcome in children with surgically treated hydrocephalus.

METHODS:

A population-based study of all 208 liveborn children with hydrocephalus, 124 with infantile hydrocephalus and 84 with hydrocephalus associated with myelomeningocoele, born during 1989-1998 in western Sweden. Aetiological and clinical information was collected from records.

RESULTS:

The prevalence of hydrocephalus was 0.82 per 1000 live births, 0.49 for children with infantile hydrocephalus and 0.33 for children with myelomeningocoele. The prevalence of infantile hydrocephalus decreased during the period from 0.55 to 0.43 per 1000. In this group, the aetiology was prenatal in 55% and peri-postnatal in 44% of the children. The origin was perinatal haemorrhage in all cases born very preterm. The mortality rate was 5% for children with either infantile hydrocephalus or myelomeningocoele. Mental retardation, cerebral palsy and epilepsy were significantly more frequent in the group with infantile hydrocephalus: 46% vs 16%, 31% vs 4% and 31% vs 10%, respectively. All children with infantile hydrocephalus born very preterm had at least one of these impairments, as did 80% of those with overt hydrocephalus at birth.

CONCLUSION:

A slightly decreasing trend for infantile hydrocephalus was observed during the 10-y period. Children with infantile hydrocephalus had a worse outcome than those with myelomeningocoele. The need for neurosurgical revisions for two-thirds of the children indicates the need for further development of prevention and treatment strategies.
