Insights
This study followed 243 children with shunted hydrocephalus, identifying complications like meningitis and shunt failure. Key risks included motor deficits, cognitive issues, and epilepsy, with higher risks linked to meningitis and tumor presence.
Area of Science:
- Pediatric Neurosurgery
- Neurology
- Epidemiology
Context:
- Shunted hydrocephalus affects numerous children, necessitating long-term monitoring.
- Understanding complications and long-term outcomes is crucial for patient management.
- This study analyzes data from 243 children over 1 to 27 years.
Purpose:
- To evaluate epidemiological and clinical data in children with shunted hydrocephalus.
- To identify risk factors for psychomotor disturbances, epilepsy, and death.
- To analyze shunt-related complications and their impact on neurological development.
Summary:
- Postoperative meningitis (22.3%) and mechanical shunt problems (30.7%) were frequent complications, with an average of 1.47 shunts per patient.
- Severe motor disturbances (34.3%), cognitive deficits (58.5%), and epilepsy (43.6%) were prevalent.
- Motor disturbances correlated with hydrocephalus severity; meningitis-associated hydrocephalus increased cognitive deficits and epilepsy risk.
Impact:
- Findings highlight significant neurological sequelae in children with shunted hydrocephalus.
- Identifies specific risk factors, including meningitis and shunt malfunctions, for adverse outcomes.
- Informs clinical practice and future research for improved management of pediatric hydrocephalus.
Abstract:
This study aimed to evaluate the epidemiological and clinical data of 243 children with shunted hydrocephalus, followed-up during 1 to 27 years, as well as to identify the risk factors for psychomotor disturbances, epilepsy and death. Postoperative meningitis and mechanical problems were the most frequent complications (22.3% and 30.7%, respectively). There was an average of 1.47 shunt per patient. Severe motor disturbances occurred in 34.3%, cognitive deficits in 58.5% and epilepsy in 43.6%. Motor disturbances correlated positively with the degree of hydrocephalus. The majority of patients with hydrocephalus due to meningitis presented cognitive deficits and a significant incidence of epilepsy. Death occurred in 52 patients and there was a higher percentage of brain tumours in this group, as well as the replacement of the first shunt device due to precocious postoperative meningitis.
