Objective: To raise awareness that patients with persistent post-dural puncture headache should be considered for evaluation of spontaneous cerebrospinal fluid (CSF) leak., Background: Spontaneous intracranial hypotension (SIH) due to a spinal CSF leak may occur following more-or-less trivial traumatic events. We report our experience with spontaneous spinal CSF leaks that occur following percutaneous or open spine procedures, a potential source of diagnostic confusion., Methods: In a retrospective cohort study, using a prospectively maintained database of patients with SIH, we identified all new patients evaluated between January 1, 2022, and June 30, 2023, who were referred for evaluation of an iatrogenic spinal CSF leak but were found to have a spontaneous spinal CSF leak., Results: Nine (4%) of the 248 patients with SIH were originally referred for evaluation of an iatrogenic spinal CSF leak. The spinal procedures included epidural steroid injections, laminectomies, epidural anesthesia, and lumbar puncture. Brain magnetic resonance imaging (MRI) showed changes in intracranial hypotension in seven of the nine patients (78%). The spontaneous CSF leak was found to be at least five levels removed from the spinal procedure in all patients., Conclusions: A spontaneous spinal CSF leak should be suspected in patients with recalcitrant orthostatic headaches following a spinal procedure, even if symptoms of the leak occur within hours of the spinal procedure and especially if brain MRI is abnormal., (© 2024 American Headache Society.)

Background: Post-dural puncture headache (PDPH) is a frequent complication following lumbar puncture, epidural analgesia, or neuraxial anesthesia. The International Classification of Headache Disorders, third edition categorizes PDPH as a self-limiting condition; however, emerging evidence, including our findings, suggests that PDPH can have a prolonged course, challenging this traditional view., Objectives: To elucidate the diagnostic characteristics and treatment outcomes of persistent PDPH (pPDPH), offering insights into its demographic profiles and diagnostic features., Methods: We executed an anonymous, web-based survey targeting individuals aged ≥18 years diagnosed with or suspected of having pPDPH. Recruitment occurred through self-help groups on Facebook. The survey comprised questions regarding diagnostic procedures, treatment regimens, outcomes, and healthcare consultation., Results: The survey achieved a response rate of 179/347 (51.6%) individuals completing the questionnaire. Cerebrospinal fluid (CSF) leaks were confirmed in nine of 179 (5.0%) cases. Signs of intracranial hypotension without a CSF leak were observed in 70/179 (39.1%) individuals. All participants underwent magnetic resonance imaging scans of the brain and spine, with computed tomography myelography performed in 113/179 (63.1%) cases. Medications, including analgesics, theophylline, and gabapentin, provided minimal short-term relief. Epidural blood patch treatments resulted in slight-to-moderate short-term improvement in 136/179 (76.0%), significant improvement in 22/179 (12.3%), and complete effectiveness in eight of 179 (4.5%) individuals. For long-term outcomes, slight-to-moderate improvement was reported by 118/179 (66.0%) individuals. Surgical interventions were carried out in 42/179 (23.5%) patients, revealing pseudomeningoceles intraoperatively in 20/42 (47.6%) individuals. After surgery, 21/42 (50.0%) of the participants experienced slight-to-moderate improvement, 12/42 (28.6%) showed more pronounced improvement, and five of the 42 (11.9%) achieved complete effectiveness., Conclusion: This study underscores the complexities of managing pPDPH. The delay in diagnosis can impact the effectiveness of treatments, including epidural blood patch and surgical interventions, resulting in ongoing symptoms. This underscores the importance of tailored and adaptable treatment strategies. The findings advocate for additional research to deepen the understanding of pPDPH and improve long-term patient outcomes., (© 2024 The Author(s).

Objective: This narrative literature review examines the long-term impact of postdural puncture headache (PDPH) in postpartum women following an unintended dural puncture (UDP) with a large bore needle commonly used for epidural catheter placement. It seeks to bridge the knowledge gap for the neurologist as to the mounting body of obstetric anesthesia literature on the development of chronic headache after PDPH with this unique needle., Background: Headache is the most common complication of dural puncture, and the risk is greatest in the parturient population. Preexisting risk factors for this population include youth and sex, and after UDP with a large bore needle, almost 70%-80% report a headache. Additionally, there appears to be a significant cohort who experience long-term, persistent headache after UDP., Methods: We performed a narrative review of literature using PubMed, searching terms that included long-term follow-up after UDP with a large bore needle in the postpartum population., Results: In women who had UDP with a large bore needle used for epidural catheter placement at delivery, the rate of chronic debilitating headache is around 30% in the months following delivery and may persist for up to a year or longer., Conclusion: Based on the existing literature, we have mounting evidence that UDP with the large bore needle used to place an epidural catheter should be understood as a high-risk inciting event for the development of long-term headaches not simply a high risk of acute PDPH. Additionally, consideration should be given to stratifying the etiology of PDPH, based on needle type, and recognizing the entity of chronic PDPH, thus allowing for improvements in research and diagnosis., (© 2021 American Headache Society.)

Objective and Background: Post-dural puncture headache is the most common significant adverse event following lumbar puncture. In this study, we investigated the possible systemic factors associated with risk for post-dural puncture headache (PDPH)., Methods: We performed a retrospective cohort study in 969 patients who underwent diagnostic lumbar puncture following a standardized protocol. We compared the clinical and laboratory profiles of the post-dural puncture headache group and non-headache group. We also identified independent factors associated with the incidence of post-dural puncture headache., Results: A total of 48 patients (5%) reported headache; 12 of these patients (25%) received a therapeutic epidural blood patch and the remaining 36 patients improved with conservative treatment. After adjusting for other variables that could be related to PDPH, we found that the development of post lumbar puncture headache was independently associated with age (OR: 0.97, 95% CI: 0.95-0.99, P = .001) and serum glucose levels (OR: 0.98, 95% CI: 0.97-0.99, P = .008).When the patients were classified by age, serum glucose levels were persistently lower in patients with PDPH vs those patients without PDPH in all age groups, with more clearly significant differences observed in the elderly (age <30 years, 103.4 mg/dL vs 106.3 mg/dL, P = .716; >60 years, 111.8 mg/dL vs 137.3 mg/dL, P = .023)., Conclusions: Low glucose levels were inversely associated with risk for post-dural puncture headache. Patients with low serum glucose should be carefully monitored for headache after lumbar puncture., (© 2020 American Headache Society.)

Lumbar puncture (LP) is associated with complications that include post-LP orthostatic headache, local bleeding, and subdural hematoma. We report a unique case of a spontaneous frontal epidural hematoma following a therapeutic lumbar puncture in a patient with a history of idiopathic intracranial hypertension. This case highlights the importance of symptomatology in patients following LPs by revealing a rare intracranial presentation that would be devastating if not discovered promptly and appropriately managed., (© 2013 American Headache Society.)

Objective: To determine the frequency and risk factors of post-dural puncture headache (PDPH) in research volunteers., Background: Despite increasing interest in measuring cerebrospinal fluid (CSF) biomarkers to investigate disease pathogenesis and diagnosis, previous case series have evaluated lumbar puncture (LP) safety only in clinical care. PDPH is a common complication after LP., Methods: We determined the frequency of PDPH in neurologically unselected HIV seropositive and seronegative adults volunteering for research, as well as the variables associated with the development of PDPH. Variables studied were body mass index (BMI), HIV serostatus, volume of CSF removed, number of previous LPs, use of pre-medication, LP position, lumbar space, number of needle passes, whether or not aspiration was used, CSF white blood cell counts, CSF red blood cell counts, CD4 count, CD4 nadir, CSF HIV viral load, plasma HIV viral load, and race., Results: Of 675 LPs performed over 1 year, headache developed in 38 (5.6%; 95% CI 4.2, 7.1). Most PDPH (92%) resolved spontaneously or with conservative medical management; 3 required epidural blood patch. Greater headache risk was associated with lower BMI (BMI ≤25 vs >25) (OR 3.3; CI 95% 1.5, 7.0; P = .001) and less prior LP experience (previous LPs ≤2 vs >2) (OR 2.1; CI 95% 1.1, 4.1; P = .03). PDPH was not significantly (P > .05) related to HIV serostatus, CSF volume, or gender., Conclusion: In this study, where tolerance to risk was low because LPs were done for research rather than clinical purposes and healthy controls were included, adverse effects were mild and self-limited., (© 2011 American Headache Society.)

Post-dural puncture headache (PDPH) is a frequent complication of lumbar puncture, performed for diagnostic or therapeutic purposes or accidentally, as a complication of epidural anesthesia. As PDPH can be disabling, clinicians who perform these procedures should be familiar with strategies for preventing this disorder. Since the best preventative measures sometimes fail, clinicians should also be familiar with the therapeutic approaches for PDPH. Herein, we review the procedure-related risk factors for PDPH, the prognosis of PDPH and the studies of PDPH treatment. We divide the therapeutic approach to PDPH into 4 stages: conservative management, aggressive medical management, conventional invasive treatments, and the very rarely employed less conventional invasive treatments and provide management algorithm to facilitate treatment., (© 2010 American Headache Society.)
