Abstract
Spontaneous intracranial hypotension is characterized by an orthostatic headache and audiovestibular symptoms alongside a myriad of other non-specific symptoms. It is caused by an unregulated loss of cerebrospinal fluid at the spinal level. Indirect features of CSF leaks are seen on brain imaging as signs of intracranial hypotension and/or CSF hypovolaemia as well as a low opening pressure on lumbar puncture. Direct evidence of CSF leaks can frequently, but not invariably, be observed on spinal imaging. The condition is frequently misdiagnosed due to its vague symptoms and a lack of awareness of the condition amongst the non-neurological specialities. There is also a distinct lack of consensus on which of the many investigative and treatment options available to use when managing suspected CSF leaks. The aim of this article is to review the current literature on spontaneous intracranial hypotension and its clinical presentation, preferred investigation modalities, and most efficacious treatment options. By doing so, we hope to provide a framework on how to approach a patient with suspected spontaneous intracranial hypotension and help minimize diagnostic and treatment delays in order to improve clinical outcomes.

Abstract
BACKGROUND To develop and validate an easy-to-use scoring system to predict the response to the first epidural blood patching in patients with spontaneous intracranial hypotension. METHODS This study recruited consecutive patients with spontaneous intracranial hypotension receiving epidural blood patching in a tertiary medical center, which were chronologically divided into a derivation cohort and a validation cohort. In the derivation cohort, factors associated with the first epidural blood patching response were identified by using multivariable logistic regression modeling. A scoring system was developed, and the cutoff score was determined by using the receiver operating characteristic curve. The findings were verified in an independent validation cohort. RESULTS The study involved 280 patients in the derivation cohort and 78 patients in the validation cohort. The spontaneous intracranial hypotension-epidural blood patching score (range 0-5) included two clinical variables (sex and age) and two radiological variables (midbrain-pons angle and anterior epidural cerebrospinal fluid collections). A score of ≥3 was predictive of the first epidural blood patching response, which was consistent in the validation cohort. Overall, patients who scored ≥3 were more likely to respond to the first epidural blood patching (odds ratio = 10.3). CONCLUSION For patients with spontaneous intracranial hypotension-epidural blood patching score ≥3, it is prudent to attempt at least one targeted epidural blood patching before considering more invasive interventions.

Treatment Patterns and Health Care Resource Utilization of Iatrogenic Spinal Cerebrospinal Fluid Leaks in the United States. Clin Spine Surg 2022; 35:E725-E730. [PMID: 35858207 PMCID: PMC9633342 DOI: 10.1097/bsd.0000000000001363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 05/18/2022] [Indexed: 01/25/2023]
Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE We aimed to characterize the treatment patterns and the associated costs in patients with cerebrospinal fluid (CSF) leak after spine procedures in the United States. BACKGROUND CSF leak is a common complication after spinal procedures. However, there is a little data regarding the national patterns of treatment choice and the associated health care resource utilization. METHODS We utilized the IBM MarketScan Research databases to retrospectively analyze adult US patients diagnosed with CSF leak within 30 days of spine procedures between 2001 and 2018. Treatment prevalence, treatment failure, and health care resource utilization data within 30 days of the CSF leak were collected. A subanalysis was performed on patients who received epidural blood patches (EBP) to better understand health care utilization attributable to this treatment modality. RESULTS Twenty one thousand four hundred fourteen patients were identified. The most common causes of CSF leak were diagnostic spinal tap (59.2%) and laminectomy/discectomy (18.7%). With regard to treatment prevalence, 40.4% of the patients (n=8651) had conservative medical management, 46.6% (n=9987) received epidural blood patch repair, 9.6% required surgical repair (n=2066), and 3.3% (n=710) had lumbar drain/puncture. Nine hundred sixty-seven (9.7%), 150 (21.1%), and 280 (13.5%) patients failed initial EBP, lumbar drain, and surgery, respectively, and the overall failure rate was 10.9% (n=1397). The median 30-day total cost across all groups was $5,101. Patients who received lumbar drain ($22,341) and surgical repair ($30,199) had higher 30-day median total costs than EBP ($8,140) or conservative management ($17,012). The median 30-day total cost for patients whose EBP failed ($8,179) was substantially greater than those with a successful EBP repair ($3,439). CONCLUSIONS National treatment patterns and costs for CSF leaks were described. When used in the correct patient cohort, EBP has the lower failure rates and costs than comparable alternatives. EBP may be considered more often in situations where conservative management or lumbar drains are currently being used.

Abstract
Background An epidural blood patch (EBP) is a procedure to treat intracranial hypotension that does not respond to conservative treatment. EBPs are commonly repeated when the symptoms persist. In this study, we used a large single-center retrospective cohort and evaluated the factors associated with repeated EBPs. Methods From January 2010 to December 2020, a total of 596 patients were treated with EBPs for intracranial hypotension. We evaluated the factors associated with repeated EBPs in the entire population, in patients with spontaneous intracranial hypotension (SIH), and in those with available myelographies. Results In a total of 596 patients, 125 (21.1%) patients required repeated EBPs, and 96/278 (34.5%) in SIH and 29/314 (9.2%) in iatrogenic population. In patients with SIH, international normalized ratio (INR) and cerebrospinal fluid (CSF) leakage on myelographies consistently exhibited significant associations (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.02-1.87; P = 0.043 and OR, 2.18; 95% CI, 1.28-3.69; P = 0.004). In patients with iatrogenic injury, INR and CSF leakage on myelogram did not show difference in repeated EBPs. Conclusions Repeated EBPs may be more frequently required in patients with SIH. Prolonged INR and CSF leakage were associated with repeated EBPs in patient with SIH. Further studies are needed to determine factors associated with repeated EBP requirements.

Abstract
Background Spontaneous intracranial hypotension (SIH) is a highly misdiagnosed and underdiagnosed disorder. Objective Update evaluation and treatment of spontaneous intracranial hypotension. Methods and Material Narrative review. Results Traditionally, SIH is diagnosed when a headache has developed spontaneously and in temporal relation to a CSF leak (evident on imaging) and/or CSF hypotension (lumbar puncture opening pressure <60 mm CSF). However, lumbar puncture is not mandatorily required to diagnose SIH. Besides headache, other symptoms such as nausea/vomiting in 50.6%, neck pain/stiffness in 33%, tinnitus in 19%, dizziness in 14%, hearing disturbances in 10.7%, followed by visual disturbances, vertigo, back pain, and cognitive symptoms may be present. In suspected cases of SIH, brain and spine should be evaluated with MRI. Dynamic computerized tomographic myelography is required to demonstrate the site of spinal CSF leak. Epidural blood patch (EBP) is a minimally invasive treatment for spontaneous intracranial hypotension (SIH) refractory to medical management and provides symptomatic relief in up to 90% of patients even in patients with bilateral subdural hematomas. The CSF-venous fistulas do not respond well to EBP, and the most definitive curative treatment is the surgical closure of the fistula. Conclusions The SIH is a distinct entity and requires a high index of suspicion for diagnosis. A post-contrast MRI should be included for evaluation of headaches. Spinal MRI should be done to demonstrate the site of leak. Epidural blood patch therapy is the most effective treatment of SIH. Most SDHs associated with SIH do not require treatment.

Abstract
Spontaneous intracranial hypotension (SIH) is characterised by postural headache and a cerebrospinal fluid (CSF) pressure of ≤6 cmH20 measured with the patient in the lateral decubitus position. Other symptoms include tinnitus, altered hearing, diplopia, photophobia, nausea and neck stiffness, and must not have occurred within a month of dural puncture. Symptoms typically remit after normalisation of CSF pressure or successful sealing of the CSF leak. An epidural blood patch (EBP) is a treatment option in those who have not responded to bed rest, fluids, non-steroidal anti-inflammatories or caffeine. We present a case of SIH successfully treated with both conservative measures and EBP. We compare our case with similar cases in the literature and summarise what is known about EBP for SIH to help clinicians take a more informed approach to managing such patients.
