[Detection of increased intracranial pressure by transcranial Doppler sonography in infants]
Insights
Transcranial Doppler sonography effectively monitors elevated intracranial pressure (ICP) in infants. This non-invasive method tracks blood flow changes, aiding in treatment assessment for conditions like hydrocephalus and brain edema.
Area of Science:
- Pediatric Neurology
- Neurocritical Care
- Medical Imaging
Context:
- Elevated intracranial pressure (ICP) is a critical concern in infants, often leading to severe neurological complications.
- Monitoring ICP is crucial for timely intervention and management of pediatric neurological emergencies.
Purpose:
- To evaluate the utility of transcranial Doppler sonography (TCD) in assessing elevated intracranial pressure (ICP) in infants.
- To demonstrate the correlation between TCD parameters and ICP levels in pediatric patients.
Summary:
- Transcranial Doppler sonography revealed decreased cerebral blood flow (CBF) velocity and increased Pourcelot index in the middle cerebral artery in two infants with elevated ICP.
- ICP reduction correlated with increased CBF velocity and decreased Pourcelot index, validating TCD's responsiveness to treatment.
Impact:
- Transcranial Doppler sonography is a valuable, non-invasive tool for verifying elevated ICP in infants.
- Its ability to be repeated frequently makes it ideal for monitoring ICP dynamics and treatment efficacy in pediatric neurocritical care.
Abstract:
The value of transcranial Doppler sonography is demonstrated in two infants with an elevation of intracranial pressure (ICP). One of them suffered from hydrocephalus and ICP increased because of her VP shunt-insufficiency. In the other case status epilepticus caused brain oedema and a rise in intracranial pressure. In both cases, transcranial Doppler sonography showed a decrease in blood flow (CBF) velocity and an increase in the Pourcelot index in the middle cerebral artery. Quick or gradual reduction of the ICP led to an increase in CBF velocity and a decrease in the Pourcelot index. On the basis of experiences of the authors, transcranial Doppler sonography is a valuable method of verifying the elevation of ICP. It is suitable for measuring the effect of treatment necessitated by the elevation of ICP. The method is non-invasive, quick and it can be freely repeated. Therefore it is applicable for monitoring the dynamic of ICP.
