Insights
The lumbar infusion test (LIT) is effective for diagnosing pediatric CSF disorders like hydrocephalus and IIH, aiding shunt management. Further research is needed to standardize protocols and improve diagnostic accuracy in children.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Diagnostic Imaging
Background:
- The lumbar infusion test (LIT) is standard for adult CSF dynamics disorders.
- Its use in pediatrics is limited by insufficient evidence on efficacy and indications.
Purpose of the Study:
- To review the efficacy and indications of the lumbar infusion test (LIT) in pediatric populations.
- To assess the diagnostic value of LIT for CSF dynamics disorders in children.
Main Methods:
- Systematic review of studies involving pediatric cohorts (≤18 years) using LIT.
- PRISMA guidelines and Newcastle-Ottawa Scale were employed for study selection and bias assessment.
Main Results:
- 15 studies including 441 patients were reviewed.
- LIT is primarily used to predict shunt responsiveness in hydrocephalus and idiopathic intracranial hypertension (IIH).
- LIT effectively predicts shunt responsiveness and detects malfunctions in IIH and hydrocephalus.
Conclusions:
- Limited and outdated data exist on pediatric LIT usage.
- Interpreting resistance to outflow (Rout) requires caution; focus on CSF pressure and venous coupling in IIH is recommended.
- Standardizing LIT protocols and fostering interdisciplinary collaboration are crucial for optimizing pediatric diagnostic accuracy.
Background:
The lumbar infusion test (LIT) is a routine part of the diagnostic process of various CSF dynamics disorders in adults. However, it is rarely used in the paediatric population due to a lack of evidence substantiating its efficacy and overall indications.
Methods:
Articles utilizing the LIT in a paediatric cohort (≤ 18 years) were included according to the PRISMA guidelines with the Newcastle-Ottawa Scale to assess the risk of bias. This review was registered at PROSPERO database under number: CRD42024625857.
Results:
A total of 15 studies, yielding 441 patients, were included in the review. The most common indications for LIT were to predict shunt responsiveness in hydrocephalus and idiopathic intracranial hypertension (IIH). In IIH, the interaction between cerebrospinal fluid pressure (CSFp) and sagittal sinus pressure (SSp) may offer valuable diagnostic insights and present a novel assessment approach. The LIT is a validated tool, especially effective for predicting shunt responsiveness and detecting malfunctions in both IIH and hydrocephalus.
Conclusions:
Data surrounding LIT usage in children is lacking and most studies are outdated. Caution is needed when interpreting resistance to outflow (Rout) due to potential overestimation, with more attention directed to CSFp and the pressure within the venous system coupling in IIH. Future studies should focus on standardizing LIT protocols across age groups with focusing more on signal characteristics rather than individual parameters and fostering interdisciplinary collaboration to optimize diagnostic accuracy.
