Introduction: Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain. Methods: We provide consensus guidelines for the LP procedure to minimize the risk of complications. The recommendations are based on (1) data from a large multicenter LP feasibility study (evidence level II-2), (2) systematic literature review on LP needle characteristics and post-LP complications (evidence level II-2), (3) discussion of best practice within the Joint Programme Neurodegenerative Disease Research Biomarkers for Alzheimer's disease and Parkinson's Disease and Biomarkers for Multiple Sclerosis consortia (evidence level III). Results: Our consensus guidelines address contraindications, as well as patient-related and procedure-related risk factors that can influence the development of post-LP complications. Discussion: When an LP is performed correctly, the procedure is well tolerated and accepted with a low complication rate.

Low cerebrospinal fluid volume and the risk for post-lumbar puncture headaches
Journal of the Neurological Sciences, 2020
Background: Cerebrospinal fluid (CSF) is essential for the medical workup of patients with neurological conditions and for disease-modifying clinical trials. Post-lumbar puncture (LP) headache is influenced by both operator and patient-related factors, including needle type and gauge, age, and gender. Objectives: We aimed to assess whether CSF volume measured based on pre-procedural brain MRI is associated with the risk of developing a post-LP headache. Methods: In total, n = 117 participants (n = 58 Parkinson's disease patients, and n = 59 healthy controls) underwent an LP and CSF collection. Of those, n = 89 underwent MRI scans prior to the LP procedure acquiring high-resolution 3D magnetization-prepared rapid gradient echo (MP-RAGE) T1-weighted images using a 3 T MR scanner. Clinical and behavioral assessments were performed for all participants, and CSF was assessed for content. The T1-weighted images were segmented producing gray matter, white matter, and CSF probability maps. Results: Thirteen participants (11.1%) experienced post-LP headache. They were younger (p = .033) and had lower CSF volumes (p = .040) compared to participants that did not develop a post LP headache. Conclusions: The results of this pilot study suggest that low CSF volumes might increase the risk for the occurrence of post-LP adverse events and should be taken into consideration when planning LP's.
Cerebrospinal fluid opening pressure in clinical practice – a prospective study
Journal of Neurology, 2020
Background Measurement of CSF opening pressure (CSFOP) is valuable and much used in the investigation of several neurological conditions. However, there are different opinions regarding reference values and influence of age, gender and body mass index (BMI). We have, in a previous study, noted possible differences in CSFOP between gender and age groups. Here the aim was to collect information regarding normal distribution of CSFOP in an out-patient sample and also include BMI. Methods We collected CSFOP from a lumbar puncture, following a standardized procedure, performed in an ordinary neurological out-patient sample. Age, gender and BMI was also registered. Descriptive statistics and linear regression was used. Results 339 patients with a normal distribution of age and BMI were included consecutively (60% females). We found a mean CSFOP of 17.5 H2O (range 4.0–30.0). In multivariable linear regression, age, gender and BMI all independently affected CSFOP. Male gender (β = 1.5, p = ...
CSF pressure assessed by lumbar puncture agrees with intracranial pressure
Neurology, 2007
The accuracy of estimating intracranial pressure in brain tissue (ICP BT) via lumbar space was investigated using preset pressure levels in the interval 0 to 600 mm H 2 O in patients with communicating hydrocephalus. Lumbar space ICP correlated excellently to ICP BT , demonstrated by a measured mean difference of 10 mm H 2 O (0.75 mm Hg) and a regression coefficient of 0.98. The concurrence supports the lumbar puncture as an accurate technique to determine ICP in patients with communicating CSF systems.
The clinical effect of lumbar puncture in normal pressure hydrocephalus
Journal of Neurology, Neurosurgery & Psychiatry, 1982
Owing to all the difficulties involved in selecting patients with normal pressure hydrocephalus for shunt-operation, a cerebrospinal fluid-tap-test (CSF-TT) is introduced. Psychometric and motor capacities of the patients are measured before and after lumbar puncture and removal of 40-50 ml CSF. Patients fulfilling criteria for normal pressure hydrocephalus were compared to patients with dementia and atrophy shown by computed tomography. Normal pressure hydrocephaluspatients showed temporary improvement after lumbar puncture. The extent of the temporary improvement appeared to be well correlated with the improvement after shunt operation. Accordingly, the CSF-TT seems to be of value when selecting those patients who will probably benefit from a shunt operation.

Background: Tap test improves symptoms of idiopathic normal pressure hydrocephalus (iNPH); hence, it is widely used as a diagnostic procedure. However, it has a low sensitivity and there is no consensus on the parameters that should be used nor the volume to be extracted. We propose draining cerebrospinal fluid (CSF) during tap test until a closing pressure of 0 cm H2O is reached as a standard practice. We use this method with all our patients at our clinic. Methods: This is a descriptive cross-sectional study where all patients with presumptive diagnosis of iNPH from January 2014 to December 2019 were included in the study. We used a univariate descriptive analysis and stratified analysis to compare the opening pressure and the volume of CSF extracted during the lumbar puncture, between patients in whom a diagnosis of iNPH was confirmed and those in which it was discarded. Results: A total of 92 patients were included in the study. The mean age at the time of presentation was 79.4 ...

Analysis of cerebrospinal fluid (CSF) obtained by lumbar puncture (LP) is an essential step for the diagnostic approach of neurological disorders, in particular neuro-infections. In low-resource settings, it is even often the only available diagnostic method. Despite its key contribution, little is known on the risks and benefits of LP in the large tropical areas where hospital-based neuroimaging is not available. The objectives of this study were to assess the safety and diagnostic yield of LP in a rural hospital of central Africa and to identify predictors of CSF pleocytosis (white blood cell count >5/μL) as surrogate marker of neuro-infections. From 2012 to 2015, 351 patients admitted for neurological disorders in the rural hospital of Mosango, Kwilu province, Democratic Republic of Congo, were evaluated using a systematic clinical and laboratory workup and a standard operating procedure for LP. An LP was successfully performed in 307 patients (87.5%). Serious post-LP adverse ...

Background: Post-dural puncture headache (PDPH) due to excessive cerebrospinal fluid (CSF) leakage is a well-known complication of lumbar puncture. Although various factors, especially the type of spinal needle, have been demonstrated to be associated with PDPH, the clinical implications of CSF leakage detected on magnetic resonance myelography (MRM) images remain unclear. The objective of this case-control study was to evaluate the association between radiologically visualized CSF leakage and PDPH. Methods: Clinical data including patients' age and gender, types of spinal needle, duration of bed rest, interval between lumbar puncture procedures and MRM studies, and incidence of PDPH were compared between patients who were radiologically-positive and-negative for CSF leakage. Results: Of the 22 patients with definite CSF leakage on MRM images, most were asymptomatic (86%, 19/22). The remaining three patients, who were suffering from PDPH, only complained of headaches and were treated conservatively. In a review of patients' clinical data, there were no significant differences in any parameter including the incidence of PDPH between the 22 patients who were radiologically-positive for CSF leakage and the 31 radiologically-negative patients. Conclusion: The significance of radiologically visualized CSF leakage should not be overestimated, as most such incidents are not associated with PDPH and do not require any treatment.
