Lumbar epidural blood patch: An effective treatment for intracranial hypotension

Abstract

Background: The literature has demonstrated the efficacy of lumbar epidural blood patch (LEBP) in the management of spontaneous intracranial hypotension (SIH). However, the underlying pathophysiology of such management remains unclear. In this study, we aim to evaluate the utility of LEBP injections in the management of SIH and develop a potential management algorithm used in the triage and management of SIH patients. Methods: We retrospectively examined the clinical case notes of 14 patients with SIH (age: 25–69 years) who were managed with LEBP injections during the year of 2016–2021. We evaluated the presenting symptoms of each selected patient and radiological findings as well as treatment outcomes. Our aim is to evaluate the effectiveness of LEBP in the treatment of SIH patients through follow-up clinical and imaging assessment. Results: About 93% of patients describe the presence of headache at presentation, while 43% describe it as being of an orthostatic nature. All patients demonstrated typical findings on magnetic resonance imaging brain. Treatment success assessed through symptomatic improvement and radiological resolution was found in 85% of our patients at a 2-month interval. Conclusion: LEBP injection is an effective method of management in patients with a diagnosis of SIH. It should be considered in all SIH patients irrespective of whether a “dural leak” can be localized through radiological investigations.

“…A limited-scale investigation involving the retrospective review of medical records from 14 patients diagnosed with SIH (aged 25-69 years) revealed that a single EBP injection resulted in symptom and radiological resolution in 85% of cases. Notably, 85% of patients experienced symptomatic improvement, with 64% achieving complete symptom resolution and 21% showing moderate improvement [31].…”
